Put together this "SPRish" build..quick rundown...
BCM VLTOR upper with a 18in. 1/8 twist,rifle length gas system
VLTOR VC1 flash hider
C3 defense lower
Magpul UBR and MOE grip
Larue SPR mount and a Luep. 2.5 -8 Mid-range scope, TMR reticle
Troy irons and a VLTOR/Tango down bipod
I have shot 69 grn match kings and it has shot well out to 400 yds. The only thing ,why did BCM use a 1/8 twist?Why not the 1/7?I am wanting to run some 77 grn fodder thrugh it at some point to see what it will do. Does anybody have a 1/8 barrel, how does the heavier bullets perform?Now for the gun porn..
