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"...

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 Bushmaste...

Remember the Colt MARS project from back in the late 80's and early 90's? Why not cutdown an AR15 lower to fit the FN FiveseveN magazines? Those mags can be converted into 30 rounders pretty easily. You could then miniaturize the upper and gas piston system. Use a pistol length system and SBR the ri...

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 di...

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 ca...

Isn't the upper the registered part?

srt-4_jon,
Yes, the upper is the registered part. Why do you ask?

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,...

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, ...

If you guys are still looking at ARs, you need to be looking at Noveske. Add a piston kit and you've got something. I just bought a matched Noveske upper and lower and I'm putting it together myself. There's no better way to do it. The Noveske stuff is very well made.

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...

My ACR barrel has been shortened (14.5"), reprofiled and dimpled to reduce weight by ADCO Firearms. A Blackout flash hider has also been added along with a Geissele SSA-E trigger. Just waiting on my ELCAN Specter DR to arrive to finish it up. Awesome rifle! It's a little on the heavy side but nothin...

The trick as others have stated is using the Glock 9mm and Glock Maritime Spring Cups. The Glock 9mm will shoot underwater. It's not big deal and I have done it numerous times. Mostly just to show others that it will work reliably and function properly, after they told me that it was impossible. The...

I think people are under the impression that Magpul has nothing to do with this rifle. That is not the case. My ACR has Magpul logos all over it, as all the plastic is manufactured by Magpul suppliers. Remington makes the military version with an aluminum lower receiver. I believe Bushmasters involv...

So, the conversion barrels and bolts will never become available? Honestly, I don't need the conversion parts today. I'm patient enough to wait while they workout the bugs, to get them right. The 6.8SPC barrels were supposed to be available in Nov. 2011. Apparently Bushmaster has pushed that back to...

My experience with Bushmaster rifles has been the opposite of what has been reported here and I have carried them for many, MANY years. I've been a fan of the Bushmaster AR since I carried one in Army Basic Training many years ago. Not sure how it ended up in FT. Jackson, SC but I did carry one ther...

It actually shot very well. Too bad the 556 didn't. They both are gone now. Sold them today.

As is turns out, my SIG522 is far more accurate than my SIG556 ended up being. After taking it to the range and putting it on paper, I couldn't believe how badly this thing shot. 3 and 4" groups at 100 yds are not acceptible to me in a weapon this expensive. I've owned AKs that were more accurate th...

I have both the SIG556 Classic and the SIG522. Both are great weapons and very accurate. As far as them being too heavy. Really! :laugh:
