Do the following check with the lower separate. You might want to use a drop block or something to make sure you don't ding things up. Cock the hammer and pull the trigger. With the hammer still back re-cock the hammer, and observer the hook on the disconnector catching and holding the hammer back. Release the hammer. The disconnector should be holding the hammer in the "cocked" position. Release the trigger. The disconnector should release the hammer which is know caught by the sear. The hammer must not move forward beyond sear engagement. If it does you have a serious problem. Check to see if your disconnector spring is installed properly. The above check should allow you to see exactly what's catching/not catching as the case may be. |

I had the same problem with a DPMS parts kit in my lower. The trigger engagement surfaces seemed just a little too soft and were getting chewed up by the hammer. I got it to work by trading out parts from other ARs until all of them functioned. I would definitely stay away from DPMS in the future. Tyrone |
| OK I did that and the hammer is not being held by the sear. When I let the trigger go and the disconnector releases the hammer, it falls. I am going to see if I can't find a different hammer to try. I'm pretty sure the sear/ spring is correct.hinking.gif |
| Thanks Tyrone, but I don't want to give DPMS a bad rap. The parts I'm using are just spares that have been laying around in my junk drawer for years (some for 20 years or more) . I also have a couple of uppers laying around that I haven't been using and thought I would build up an inexpensive lower and use the combo as a knock about gun for my UTV. Thanks for the imput though. hy.gif |
