I really don't want to leave bad review but I think its important that buyers know that installation was difficult and I build ARs weekly. I've never had this much trouble installing this roll pin. For some reason the roll pin wouldn't fit. I ruined two pins trying to install it. Tube hole must have been bad, not sure but thankful I had extras. Other than that everything else was great. Great company, great communication and will buy from again.
