i got my 6.8 upper all put together and head spaced.
now i am working on the lower.
for the upper i used questars 6.8mm spc ACR SS barrel with matching bolt sold by them on an STI A3 upper from easy guns. i used an adjustable gas block since i'm not sure how the 6.8mm is on gas if it needs addjustment. and free float mid forend.
i cant wait to shoot it. i will prob put it on an older lower i have here just so i can use it soon.
