I got a smoking deal on 3 16" mid-weight "blems", normally over $300 for $125 each. Someone programmed the CNC wrong, putting the barrel's shoulder at carbine length on a mid-gassed barrel. I simply used Vltor clamp on gas blocks and gifted all three rifles to relatives. Each were well under moa with 24.5 grains of Varget and 69 grain SMK's seated at 2.250".
