Armed Eye Doc Posted April 13, 2023 Report Posted April 13, 2023 Welcome to the forum. While the rifle is still apart, measure the gas port. It is a frequent issue with reliability in these rifles.

Thank you to Albroswift for the direction! Welcome aboard, man - any friend of Albo's is a friend of ours. You mentioned UBR Gen 2 stock. Buy an AR15 Carbine H3 buffer for that thing. Very first. Not an H2, not an H1, the H3 AR15 Carbine buffer, 5.4oz. You'll need either the Armalite EA-1095 recoil spring or the Sprinco Red recoil spring for it. Those two items, combined with the stock you're running, will bullet-proof your recoil system. For good. After that, we move on. Welcome here. Edited April 14, 2023 by 98Z5V
