Perfect mags, perfect function.

I have a few of these in 20 and 32 rd. I also have quite a few of the holy grail metalform 32 rd mags. These are every bit as solid and function just as perfectly as the metalform. In fact, in my piece, using a KAK mag block, the ASC mags load with more authority and a bit easier than the metalform mags. Feed issues are nonesistant; M&P lower with mag block, Aero upper, BA 8.3" 9mm barrel and a CMMG bolt, about 1KK rounds through it now and I have never had a single feed issue. Using Speer lawman 147, Am Eagle 124 and 147, S&B 124 and Federal 115, all brass fmj. These are GREAT magazines, they may have had issues in the past or in other calibers but these are flawless. The polymer follower rocks less than the metal follower in the metalforms.

Bolt hold open fail

The back side of this magazine's follower does not stick up far enough to fully engaged the bolt hold open in my Spike's lower. The only point of me getting a colt-style lower is LRBHO. manually locking the bolt to the rear and inserting the mag revealed a ton of space between the follower and BHO. Don't

Excellent quality magazines

Work perfectly. I'm using these with a KAK mag block and CMMG bolt, ballistic advantage barrel. A 9mm AR platform is probably the most fun I've ever had and I would say that I've easily put 1000 rds + through it of all types of ammo (brass case, various projectile weights). I have not had a single jam or malfunction and the lrbo works perfectly. I have Metalform mags also which were a bit more expensive when I bought them, and in terms of function, I can not determine any difference between the two brands. If anything, the steel used in these ASC mags seems even sturdier than the metalform, although the exterior finish is not quite as "nice." Don't hesitate to use these!

Fit, Finish & function

I installed a new Ghost mag conversion block in my mil spec AR lower. So far the results have been spectacular using the ASC Colt style magazines and at these prices an excellent choice!

No Jams

Bought these for a 9mm pistol build, CCMG colt lower and a foxtrot-mike upper, solid fit , no jams, kind of stiff to load at first . but got easier with use
