After putting together a measly 16 rifles my favorite caliber in the AR platform is the 5.7x28. A real eye catcher at the range and with a 20round magazine inserted after the top has been cut and the guts removed, there is no moving parts on the outside and the empty mag acts as a brass catcher. The real problem is I keep thinking I am going to set up an upper but find myself building it into a complete rifle before it is all over.

How do you feed from and eject to the same mag? I want pictures of this and a video of it in operation. Cause I just don't believe it.

I picked up a 338 fed AR-10 Armalite last year. Listed for 1900, i got it from local gun shop for 1650. Super heavy compared to stag 6.8, but we (family members) killed 3 moose, several caribou, and a couple bear with it over the last 6 months and happy enough with the gun for hunting within 500 yards. Gun dead on at 100 yards, one of the moose was 400 yards, aimed at backbone, hit in kill zone, so I figure it dropped 8-10 inches as a rough estimate with 210 nosler partitions. AR-10 has 21 inch barrel, but they are offering a shorter barrel, 18 inches; thinking about another purchase.

AIG has a nice AR-10 video, I think it's on the AR-15 dvd as an extra, but well worth getting, at least it was for me.

I'd like to get a 338 lapua myself, just don't know enough about what's the best way to go, so I keep using my 30-378 which I think is comparable.

well i want to keep you guys updated. the same place i "rented" the 338 from got another one in .308 with a very similar setup that they let me test out. the scope on the .338 cost over $1500 and was a leupold something or another. i dont know what the magnification was on that thing but it was up there. the .308 that i tested had some old bushnell 12x scope on it. i still made 3 inch groups which is pretty darn good considering that i could only just barely see the target at that range with the scope that was on it. im thinking the .308 will be plenty accurate enough. it will be plenty light on my wallet to shoot comparable to the .338 as well as easier on my shoulder. that damn lapua packs a wallop! in my honest opinion i believe that if both the .308 and .338 had the same scopes that i could shoot almost exactly the same with both because its aweful hard to hit a target that you can barely see.
