I put together an 16" mid-gas upper using a BA 'modern series' barrel. No complaints, I'd buy BA again.
100 yards, M855 equivalent from PMC.
Absolutely nothing wrong with that with M855.
Great shooting MontanaMarine...
My buddies old school Bushmaster 20" HBAR loves the stuff. He'll routinely shoot 1.5" 10 shot groups with that rifle and the old green tips...
He'd be a contender if he could just get his group centered on the damn target.. Ha ha.. Takes the fun out of it in competition...
