I gave my new build a good workout yesterday for the first time. All was well, but the trigger pin kept wandering out of the side of the lower. What is the fix? |

When the hammer and the spring are correclty installed the U shaped portion of the hammer spring is against the back of the hammer and the springs legs are on top of the trigger pin with one leg resting on top and in the groove in the trigger pin. As the hammer is pushed back into the firing postiion the spring tightens. Two common errors are to place the hammer spring legs under the trigger pin or to place the hammer spring backwards on the hammer. www.ar15.com/content/manuals/TM9-1005-319-23.pdf If you look at pdf page 190 the hammer identified as the M4A1 in the picture has the spring installed on the hammer correctly. |
