[QUOTE="TR1Hemi, post: 2609381, member: 122752"] If the maker of the bolt catch is not Aero. Look at interference between the bolt catch and the inside of the upper when it is installed on the lower with an empty mag. If the bolt catch moves further without the upper on, the bolt catch is hitting the inside of the upper. This crap happens when "building" AR10's as there is NO MILSPEC. The trigger group is AR15 mil-spec much much of the LPK is AR10 specific, and since there is no MILSPEC parts differ based on the UPPER. I had this exact issue with an 80% lower and PSA upper, I ground the bolt catch a bit where it was hitting the inside of the upper. [/QUOTE]
