Great product
Great for free float rails. Use stainless pins, lubricant and roll pin punch (from other review.).

Nice piece... User error?
I'll give it 4 stars... Had an issue punching the roll pin thru easily. Actually had to order another roll pin. I'm guessing user error as it is my first ar build.

CNA gas block
Fit was excellent. Put it on my Anderson 16" RF-85 barrel . Very robust construction, fit barrel perfectly . will definitely use again for next upper build.
