Relatively new to the Ar-15.......While shooting yesterday, (Carbine, RRA Lower/YHM Upper) second round would not eject. First round in each attempt works fine, second won't eject. I wasn't getting the good Sproing on the second. I had been shooting steel case Monarch, but only about 10rds when the problem started. I tore it down and checked for build-up in the chamber........clean. Nothing gummy or sticky. Then in handling the rifle, noticed that the Gas-block set-screws had backed out, and the block would slide forward on the allignment pin. Could this be causing the problem........allowing enough blow-bye to keep it from cycling the second round, and if so, why will the first round work perfectly?
Any advice Appreciated!!! |
