Perhaps more will be revealed about the ACR at the SHOT Show in January. Remington Defense makes the military version of the ACR which isn't for sale to civilians. You can't get a Remington ACR yet. Hopefully, that will change. Bushmaster has recently announced first quarter sales of conversion kits and shorter barrels :lmao: ...but they have said that before, so I'm not holding my breath.

It seems natural to me that Remington would sell a civilian version of the ACR, as that is what they do. Remington Defense could handle military sales and Bushmaster could be done away with. In this economy, I would think that would streamline the company a good bit. Honestly, I think of my ACR as a Magpul Masada anyway, as it has Magpul logos all over it but doesn't say Bushmaster anywhere on it. There is one B.F.I. stamp on it but it doesn't say Bushmaster and there is no snake logo on it either.

The rifle does shoot very nice. Much better than an AR does. I've shot 1-1.5" groups with mine at 100 yards. I looked at the SCAR but it has even less parts availability than the ACR. If you can believe that. Nothing is available for the SCAR from FN.

1.5 MOA is pretty standard with the ACR and SCAR. Definitely good. Nowhere as good as a custom billet AR, but as good or better than any forged production AR for sure.

And Remington will sell the civi version of the ACR. It won't change at all from what is being sold now I am told, other than the Remington labeling.

This being an FN Forum, I can't imagine too many ACR purchasers, considering that the SCAR and ACR are basically in identical categories with somewhat identical capabilities.

ACRs around here are cheaper than SCARs. That would be the only reason I could see. I don't own either.

Can the SCAR interchange calibers? IF the ACR ever gets the other barrels/assemblies (which is the whole point of the "Adaptive" ain't it?) out I will probably get one.

SCARS handle better than ACR's. I'm not speaking on ergonomics as it is different per person.

I am referring to the shooting of the firearm.

Re: Bushmaster ACR

Post by SamM » 24 Feb 2012, 11:33

Here is my much modified Bushmaster ACR. It now has a Geissele SSA-E trigger and an ELCAN Specter DR sight. The rifle has been lightened to 7.5lbs. With the ELCAN sight as pictured it's 8.7lbs. Almost 1lb has been cut from the handguard and buttstock by doing some creative sculpting with a hacksaw, a rasp and some light sanding. I have a few more places on the rifle, that I would like to thin down but will wait for now.

Some parts have finally started to trickle out of Bushmaster/Remington. I have purchased 2 extra sets of gas system components but a few of the barrel parts are not available yet. So far, I have purchased a chrome-lined FN 5.56 NATO 1/7 barrel, 5.45X39, 6.8ARP and .223 Wylde melonite barrels. Still waiting on a 7.62X39 barrel, but I have purchased a new 7.62X39 bolt and a magazine.

The SCAR is an excellent weapon. I don't want to take anything away from it. The ACR has a couple of nice features that it doesn't though. AR triggers will work in the ACR. Geissele does make a trigger for the SCAR but it's a little more pricey. A standard Geissele AR15 SSA-E trigger can be picked up for $179 and some change. The ACR also uses a standard type M4 barrel. With a little machinework, they'll fit the ACR and are available in a wide range of calibers. The barrel needs to have a mid-length gas sytem and a gas block mount that's .750".

Not trying to change anyone's opinion about the ACR. Just trying to get some information out there.

Great work, Sam.

I like the purposeful cuts you have done to your ACR platform.

That's a lot of calibers and a lot of keeping up with different mags. I'm sure you'll make an easy-to-use labeling system for the magazines.

Having AR compatibility is a big pro to the ACR. The G trigg for the SCAR goes for $400~. That's laughable, as any experienced person can do a very safe trigger job to most carbines; I'm pretty sure the SCAR is no exception.

G triggers are great, though. I use them very frequently, from the 2-stages to the S3G triggers for long matches and they have done well.

Re: Bushmaster ACR

Post by SamM » 25 Feb 2012, 05:21

Thanks blueorison!

The cuts make the weapon look a little more spaceage to me. In the end, it was well worth the effort. Cutting into a $2100 weapon made me a little nervous. I looked at it for about a week, before gathering up the nerve for the first cut. In my early life, I was a bit of an artist, so my attention to detail is sometimes over the top. More cutting is planned. I'm all in on the ACR weapon platform, so I don't expect the ACR to go anywhere soon. Besides, I've cut it up. It's a very nice shooting weapon. Recoil is smooth and the trigger pull is the best! Taking it to the range is a very interesting experience as everyone that sees it wants to shoot it. They all want to see how it comes apart too. Numerous times as they go and get their buddies, to come over to see it. I'll usually let anyone shoot it, if they have .223 rounds. I don't like to supply both the ammo and the rifle. :D One guy had some steel case that I had never ran through it. The ACR ate it. At first, I was concerned but it ran fine. I'll soon be doing some testing to see how well the ELCAN reticle tracks with the recommended 62Gr XM855 ammo. Recently picked up a 1200rd case of that from Cabela's.

All of my other rifles, have been sold off or given away. Last week, a Rem 700 and Marlin 1895 went down the road. I do have a custom Noveske N4 (M4) that I'm building up but even my hunting rifles have all been sold off. My daughter got the last of it. A Chinese AK, Bushmaster M4 and Rem 700 in .308. I'm trading another Bushmaster AR for some work on a motorcycle. My new Noveske will be a training rifle and backup to the ACR. I believe everyone should have at least one M4. I'm not a fan of DI guns, so it will be piston driven. My plan is to just have two primary multi-caliber rifles. The ACR and a new DTA SRS Covert bullpup rifle that I am saving up for. My plan is for just one higher end long-range optic that will be swapped from the ACR to the SRS. It will sit in a LaRue mount. It will probably be a Schmidt & Bender PMII or a Horus scope. The ACR has the ELCAN and I'll likely get an Aimpoint T1 for it, that will also be used on the Noveske. The DTA calibers will be: .243Win, .308Win, .300Win Mag and later a .338LM. All the barrels will be either 18 or 20".

The most important calibers to me, for the ACR are: 5.56X45, 5.45X39, 7.62X39 and the 6.8ARP. Anything else will be gravy. Many more calibers are possible. Everything from the .17 Remington and .204 Ruger to the .300 Whisper and maybe even the .458 SOCOM. The caliber selection that I'm looking at should give me good options for any shooting or hunting that I have planned. My big game hunting is limited to whitetail deer on my property. The 6.8 can handle that. The 5.56 and 5.45 are very similar but I'd like the option of shooting any 5.45 that I may come across. My 5.45 barrel is melonite coated. I have always be a fan of multi-caliber weapons. We've never before had the options that will soon be possible. There is still a long way to go with the ACR but Bushmaster has a July release date for the 6.8 bolt and the 7.62X39 bolt will soon be available from an aftermarket source. The magazines should be fairly easy to keep track of. For 5.56, I will use the Lancer L5 AWM, the 6.8 will use PRI or Barrett mags and the 5.45 will use regular aluminum GI type mags with modified followers. I just bought a 7.62X39 mag from PWS. It has a very noticeable curve and looks like nothing else. You're right though, they will all be marked to avoid confusion along with the bolts. The Noveske will get 7 Magpul M3 magazines.

I was the first person that was able to score gas system parts from Bushmaster. My call just happened to be on the release date for those parts. The barrel parts will be available as soon as they catch up with the demand for the new 5.56 barrel conversions. Meaning, all of those parts are being held for 5.56 barrel production. Bushmaster/Remington will be releasing those barrels in late March. That's what we have been told but we've all heard that before, with nothing happening. I remain confident that Bushmaster will support the platform. If not, the aftermarket will step up. It would be very easy to produce ACR bolts. Only one machining process is different. The cam pin is at a different angle.

As I go forward, I will post about the rifle and caliber conversions.

Gotta hand it to you, Sam, you know what to do.

I do not have the option to be a gun collector, so I've arrived at your path before I even took it.

I plan to have only one long range system and one or two short-medium range system in different calibers.

As of yet, I'm not worried about getting a carbine or long-range rifle. I find it impractical to CCW most carbines, and when I do go hunting, I hunt with handguns. For multigun and 3Gun, my friends allow me to use their guns, or I would not be able to shoot at all.

I actually used the same sight setup and trigger setup in matches before; Elcans with G triggers. If you watched the last video I posted, you would be able to see two of the carbines I used, topped with different Elcans. One is owned by my good friend in the video, who is also a member of our forum. Today at 3Gun I was using (or RUNNING, because I feel that I'm tacticool..not :lmao: ) a LaRue 18in with Swar. 1-6x and G trigg. It RAN very well. I also did RUN with it and there was a stage wherein I did run and shoot while RUNNING (actually RUNNING my gun). Anyway, said that to say that I can empathize with your mindset, going into this form of firearm setup. :thumb:

I do like Aimpoints; the T1 has a very small footprint and takes up very little real-estate (operator talk). It's small and compact (regular talk). Though overpriced?/expensive.

I appreciate the fact that you are allowing for many calibers, though I feel it excessive. But that's none of my business, because it is your money!

The LaRue optic mounts are very good. I have only seen one that didn't work correctly, but it was a used one and I don't know what the previous owner did to it.

I was hanging out with Mr. LaRue's son today, coincidentally.

Anyway, cool beans. Sorry for the tangents, my brain is everywhere. I saw two guns blow up today, and am very sunburnt and tired.

Re: Bushmaster ACR

Post by SamM » 26 Feb 2012, 00:29

I appreciate the input blueorison!

There were just too many guns sitting here in my safe unused.Multi-cal is the way to go. That is a lot of calibers and it could easily change. I have already commited to the .223 Wylde, 5.56 NATO, 5.45X39, 7.62X39 and the 6.8 as I have purchased barrels in these calibers for the ACR. Like most, the 5.56 will be my 'go to' caliber of choice. The .223 Wylde barrel was purchased on a whim, before I found the 5.56 machinegun barrel from Spike's Tactical. That barrel is very thin and turns my cutdown ACR into a 7lb rifle. In a worse case scenario, the 5.45 and 7.62 Russian calibers let me shoot any of that ammo, that I may happen upon. Those let the ACR replace both my AK rifles. Which I felt was important. The 6.8 gets me in on pig hunting, deer hunting and medium range precision shooting with a better optic. With the exception of the .223 Wylde, I feel these are the minium in the ACR. A SBR .300BLK gets me a CQB platform from the same weapon. I may spring for a can later on.

The DTA Covert will be needed in .243 for coyotes, small varmit hunting and possibly deer. That rifle is very modular and very versatile. It would be a great ranch rifle in .243 with a smaller optic and then a precision tool in .300 Win Mag and a long-range optic. The .300WM was my regular deer caliber of choice (with heavier bullets) and after shooting .308 rifles for years, I really enjoy it for long-range shooting. I can hunt anything with that caliber. Those may be the only two calibers that I need. The .338LM is not really necessary and only on my wishlist at this point. The .308 may or may not happen. A .338 caliber DTA can lets me suppress this weapon platform in all the available calibers. It could happen as well.

I've also sold or given away all my Glock pistols. The wife got my G26. The G19 and G17 went down the road. My FiveseveN is my only current pistol. At some point, I'll need another CCW pistol. May go with a Gen 4 G19. Don't like the .40. Stuck on the 9mm since my GSSF and IDPA days.

The Vortex optics appeal to me but I'd rather step up to european glass for the DTA. There is a Vortex SPARC on my daughter's M4 and I have a Vortex Viper PST 1-4X24, that I just added (read: gave) to her Rem 700 (.308) with a Vortex QD Cantilver mount. It will also go right over onto the M4. The Aimpoint is pricey but with having far fewer rifles, I can afford it. Same with the ELCAN. It was very pricey but worth it in the end. I see two highend riflescopes for the DTA, in LaRue QD mounts. A 1-8X short range scope and a 5-25X for long range. Both with matching HORUS reticles. They would also work on the ACR. Just one man's, two gun plan! Well, three if you count the FiveseveN. I'll never get rid of it! Best weapon I have ever purchased!

Buying more and more, no longer appeals to me. As I get older, I feel that less is more! I'm in the process of building my wife a huge new house. It's taken much longer than I planned, due to her losing her job and a worsening economy. Soon there will only be the two of us and it's way too much for us. We'll probably give it to the daughter and move into my mom's little cottage that my father built her. It just makes more sense!

Thanks!

Re: Bushmaster ACR 1/7" twist 5.56x45 NATO conversion done!

Post by SamM » 10 Jun 2012, 22:47

Here is the first caliber conversion done on my Bushmaster ACR. The barrel pictured on the rifle is a 1/7" twist chrome-lined barrel in 5.56x45 NATO and made by FN for the M4. It's from Spike's Tactical and is 16" long. The barrel cost me $249. Yes, the .223 Remington has the same basic cartridge dimensions as the 5.56 NATO, but they are very different due to pressure differences. The ACR shoots very well in this caliber but is overgassed due to the larger gas port in the 16" FN 1/7" M4 barrel. Bushmaster does not offer the 1/7" twist barrel for the ACR yet. The only way to get this is to do it yourself. This barrel works very well with the M855 round that my ELCAN sight is calibrated for. A friend and I are planning to make an adjustable gas block to remedy the over-gassing problem. We will add a set screw to the gas block that will allow the amount of gas going into the system to be regulated. This has been done before and works great. It's ironic that my ACR now uses an FN barrel and the same PWS flash suppressor found on the FN SCAR. This is the way the ACR should have come from the factory.

Image

I have also just finished a 5.45x39 Russian conversion for my ACR. It shoots fine but is over-gassed too. The gas block on that barrel will also be drilled for a set screw. The 5.45x39 conversion uses a melonite coated barrel from Spike's Tactical and bolt that was machined to fit the 5.45x39 cartridge. The new 5.45 bolt is just a stock Bushmaster ACR bolt that has been machined by Arctic Arms. My next move is to have both barrels cryo-treated by 300 Below Inc. All of my parts were recently sent to Argonauts ReInc in Colorado to be used in a 7.62x39 Russian barrel that I purchased from AR15 Performance. I'm sorry that I don't have an pictures of the 5.45x39. Didn't take any when I tested it and it's apart now for the cyro-treatment.

When everything is finished I plan to do some bench tested to see if the groups tightened up any from the cryo-treatment. I'll post pictures then. Once Bushmaster releases barrel parts, I will be able to shoot the 5.56x45 NATO, 5.45x39 Russian and 7.62x39 Russian. My next conversions are the 6.8ARP (an improved 6.8SPC) and the 6.5Grendel. After that we are going for the .204 Ruger and the .300 Blackout. These last two cartridges use standard .223 Rem magazines and bolts.

Thanks for looking!

Re: ACR 7.62x39 Russian caliber conversion

Post by SamM » 04 Jul 2012, 19:48

Here it is. The 7.62x39 Russian caliber conversion is finished. The bolt is from Argonauts ReInc. and the barrel is from AR15 Performance. This thing shoots nice. We are taking it to the range tomorrow for some testing. The magazines are from ASC. I'm forced to keep it this caliber because Bushmaster has not released barrel parts yet. Once they do, I'll be shooting the 5.56 NATO and 5.45x39 Russian calibers too. Next on the list is 6.8ARP. That barrel is getting ready to be machined to fit.

Don't you have to re-zero every time you change calibers though? I notice, in the pics, your optics come & go.

Re: Changing calibers!

Post by SamM » 06 Jul 2012, 01:34

As I said, it is not really possible to change calibers yet. Remington has not released the required parts. It would required me buying extra rifles and parting them out to get what I need. I'm not quite ready to do that yet. Once they release the parts, I will have the 7.62x39, 5.45x39 and the 1/7" 5.56x45 NATO. Still in the works is the 6.8ARP (an improved Gen 3 SPC), 6x45, 300BLK and possibly the 6.5 Grendel. I'd also like to have the .204 Ruger later on for Coyotes.

The ELCAN does not loose zero when removed as long as the caliber remains the same. I've done this numerous times and it retains zero. When switching calibers the plan is to change back to the previous zero settings. The ELCAN uses external adjustments rather than internal adjustments. It only requires each caliber to be zeroed once. Write the settings down and then return to them as needed. Basically, you mark a starting point (somewhere in the middle) and all the settings for each caliber are measured from there. Simple and easy.
