The Firing Line Forums - View Single Post - Perhaps a silly question. Practical accurate range of a AR10?

I have experience with 2 Armalite AR-10T rifles.

Both of them were purchased in .308,then a .300 RSUM upper was added as an accessory.Off the top of my head,I think you will find the .300 will get 2900 fps with a 180 gr match bullet.,How far can you hit something?

Accuracy? Scary.A free float,heavy bbl AR-10 is not afraid of any production bolt action repeater. We mostly shoot 3 shot groups(spare me,you can shoot 5,I can shoot 3,use less ammo,and my bbl lasts longer)

Both rifles,some days,1 1/2in groups,and my brothers grumble.Some days,a quarter,maybe a nickle size groups.On a bad day,wondering what is wrong???Maybe 2,2 1/2 inThats not so special,till I tell you this is at 300 yds.Don't believe me? I don't blame you, wouldn't believe it,either.I'd call BS,myself.

Anybody else shoot an Armalite AR-10 T?? Go talk to them.
