Have a stock BM lower, trigger, tube, BCG (w/ 4000rds) and all. Except I put in a wolff extra power recoil spring. It is made a noticable improvement in recoil and feel. However, out of the last 1000rds with it on, I have had three slam fires. With one pull of the trigger - it shoots a round, quickly loads another shoots that and loads another and stops. Could this be the spring? Everything else seemd to be fine. Any ideas I should look at? |

sounds like your trigger may be too light rather than the buffer spring....When you pull that trigger make sure you pull it all the way and dont release it too fast...I used to have this same problem with the jewel trigger when set too light....assuming I am understanding your problem. What you descibed is not a slam fire...it is a trigger doubling up. |
I had this happen shooting WWB ammo with a generic M4 stock. I replaced the buffer with an H-buffer and the problem stopped. Tex78 |
I wondered about this as well, but it sounds as if he has a stock single stage trigger, so nothing to "set" to light there, unless he's bending springs, etc. which he doesn't allude to. I did wonder if he was starting to have disco problems. I wondered if he did the standard disco test, pull the trigger, push the hammer all the way back, release trigger, and see if disco catches the hammer, etc. More importantly in this case trying to pull the hammer forward with his hand after the disco catches it. Although he didn't say, I assumed the bolt was clean, and free of gunk in the firing pin hole. Also wondered if his firing pin could be bent ever so slightly, causing it to jam in either the forward or back position within the bolt. Rollling the pin on a flat table will answer that one right quick. All that aside, after he answered that the last shot would hold the bolt open, my first thought was some kind of trigger problem, so I'm in agreement with you based on the facts so far. |
