Now, what is the best strap system for walking with an Ar15!!!!!!......and the list goes on

top-mounted M60 sling (the one with the pad) served me well patrolling in Bosnia. There's not much difference between the most expensive and the cheapest slings. Comfort is second only to ability to present.

I found an illustration of that set up. My ar has a free floating barrel so I believe a sling has to be attached to the hand guard (Yankee Hill). I have never carried a rifle but I know the sling must be comfortable.
I am open to more suggestions.

In case anyone is interested I decided on the ammo to stock up with. I am going with the 60gr Hornady V Max.

Mk262 Mod 1 would be my vote.

I was going to stay away from this thread but...

many think that the more frangible rounds, at closer distances, are the best bet, or the MIL AP rounds.

However, back when MIL first started searching for their SOPMOD Mk 12 round, later designated Mk262 Mod 0/1, they went to the CMP Highpower shooters; long story short, they used their info and the same round loaded to MILSPEC (probably the only time I've used this word LOL!). Highpower shooters load the round past safe pressures, as they have different chambers than MIL rifles.

They were aiming to maximize lethality at longer ranges, with the Mk 12 platform. The round performed brilliantly. What most don't know is that at closer ranges, like 100 yds and under, the round is extremely devastating.

So yes, I would go with that round. I don't believe in "do-alls", but one reason, I think, that Tactical Fanboys drool over the round (other than it's a SOPMOD special round), is because it works for close and long distances, extremely effectively.

You can't. It's not sold and was never sold to the public. Blackhills released only the "Seconds" to the public that did not meet MIL standards, and it was very limited and not announced, and only found in Cabelas sporadically for a very short amount of time. Even within MIL, it was a round restricted to those who were trained and carried the Mk 12's.

Obviously, AR15 members went ballistic over this, and prices on Gunbroker was quite high, just for the "Seconds".

The only way you can source it is from MIL that is part of the Mk 12 program, which isn't many.

If you're very serious about getting your hands on some, I have a few authentic Mk262 Mod rounds, still in their package. I did a test with them with my Highpower HBAR rifle that I posted on the member's area of the forum. I think I have removed it since, though. I'm not sure I want to let them go :)

Since I can ask you instead of just googling, can one buy the projectiles and load them ourselves?

@Pain:

Yes, since this is what the Highpower competitors have done, before the MIL got ahold of it and tweaked it for MIL use. You won't get the powder blends and the formula.

I can tell you for a fact, staring at the casing of the Mk262 Mod right now, that it's LC brass, they use the same rounds we do, 77grainers. If you're really serious about reloading it, you can shoot me a PM and I'll share what I know. We use LC brass for Hipower; not all brass are on the level, and only a few mfg's make them good enough to stand up to the high standards and pressures of long range 77grainer loadings. The pressures are extremely high for Highpower (though, not everyone loads to the same formula as my Coach and I do).

I'll give you an idea; when I was shooting the Mk 262's in my testing, I utilized a flatwire, increased lb'age spring in the test platform. The recoil was substantial for a 5.56 round. So much so that it actually took me a bit off guard. It wasn't .308, but perhaps .300 Blackout with a nice comp., and snappier.

When I shoot the hotter Highpower loadings, it's a lot more kick (still not .308, obv.). It's the only time I've ever felt the 5.56 AR kick. Even SBR's don't kick like that.

Mk262 Mod 1 77gr SMK OTM is the most destructive 5.56mm round in tissue.

It has an awesome combat reputation in 3 wars plus.

It is a great round for sure. Excellent out of a Mk12. Blackhills is not making it with a Nosler HPBT for the military. Not much different from the old SMK. Apparently Sierra got in a tiff over the mil contract and refused to supply or something. Still can get the SMKs on the civi ammo, and the loading is identical I am told.

FYI when ever I get caught up with T6 I plan on doing a run of Virgin LC brass .223 loaded with the 28gr PFP. That should do some damage.

It can be, since they got their formulas based off of the CMP shooters' loadings.

But it still won't be the Mk262 Mod because it didn't come from MIL! :laugh:

Apparently the super duper death ray round is available to us civilians now?

It has been out for a while;

you can readily reload to your rifle with the 77 SMK and achieve tighter groups than with the "super death ray round".

There are several companies that offer a Mk262 Mod1 equivalent, but it's good to see Blackhills themselves selling the round to the public now.

When i had an AR i used Doubletap 77gr OTM. It was loaded to even higher advertised velocity than Mk262, and like the Mod 0 version of Mk262, it used the Nosler 77gr OTM. Supposedly it is a little shoter than a SMK 77gr bullet, so is easier to stabilize in a 1:9 gun.

From all that i'm told, the 77gr SMK bullet does not like 1:9 twists.

Mod 0 uses Nosler? That's news to me.

I never listen to what gun people say... you can't blame me... how many times has that guy behind the counter told you ss190 is banned to the public? :lmao:

Being not an avid listener to "truth" people mill on forums, I took a 1/9 twist carbine and shot Mk262 Mod 0 out of it. Mostly just to spite the all-knowing internet commandos who thought they even knew what they were talking about when they had never even seen the round in person.
