Will magpul mags function in the Armalite?
Yes, they fit the current production AR-10A but not the older AR-10B.
Bingo. The op is trying to decide between different brands. Mine is the older (pre 2011) Armalite AR10T. It will only take the proprietary Armalite mags. They are great magazines, but are expensive. The thing I like about my S&W performance center is it takes P mags. The same can be said about the Remington R25 and DMPS panther arms AR308. My old boss has a DPMS and it is a shooting sob, but it is heavy as hell. Probably one of the best shooting ar308 rifles I've personally seen. Mine shoots sub moa 3 shot groups all day long:
But don't count on that type of accuracy over a 10 shot string:
That's where my 6.5 cm really shines:
I'll stand behind the creedmoor as being the better choice. If guys are talking about finding ammo, sometimes its easier to find 6.5cm vs 308w. If you guys are having a hard time finding 6.5cm ammo, you just aren't looking for it.. Whats weird is I was at a country store way out in the middle of nowhere and right next to the 270 and 30-06 ammo was a box of creedmoor. Go figure....
