Hello all, got a question. Bought a DPMS Agency rifle. 556 chambered, went to the range and everything was gravy. Got home, cleaned, everything was gtg. Function check ok. Went t clean tonight and everything ok.......preformed a function check. Rack, pulled trigger, hammer fell, racked again while still holding trigger, let off trigger expecting the pop, no pop but the trigger fell. Repeated this and the same thing happend. It does this with the upper attached, but with the upper off , preformng the function check it works 50% of the time. What the hell is going on with my rifle? thanks in advance Irishrifleman |
Would be my guess as well and if a new rifle, either there is a bur or the FCG (disco in general) is binding up from fouling. Pull the FCG and give the whole mess a good cleaning outside the rifle. Confirm that the trigger will rotated on the pin, and the disco will rotate in the trigger on the pin installed outside the rifle (leave the disco spring out for this test). If they will not, check for edge of channels for burs and resolve them if needed. When you go to reinstall the CLP pre-lubed FCG parts, remember that the disco spring installs with the large coil downward into the back trigger slot. As for the hammer pin, install the side without the annular groove in first, since if you install the grooved side first, you will have to drive it past the hammer J spring (read easier to install the non-grooved side first). as for a direction of the pins, it doesn't matter since only one leg of the hammer spring rides/retains the trigger pin via the groove (read hammer spring legs ride on top of the trigger pin, not below it). www.ar15.com/content/guides/assembly/lower/ |
