I have been piecing together the parts for a new AR build over the last 9-10 months, and finally decided I want a 18" 6.8 SPC build with an MLOK upper.
Who has the best complete BCG going for 6.8 SPC? I see FailZero has a Nickel Boron coated one, but I know nothing about them. Stag has one. Daniel Defense has one, and they're my first choice but a bit spendy.
Thoughts about my options? Also as to barrel for an 18" 6.8.
