I have a problematic PSL that will double tap with a recoil buffer installed. What is going on? Trigger/disconnecter badness?
Easy solution - forget the buffer. But without it the bolt carrier will occasionally get off the rails and will be stuck back/open. Pulling back/manipulating the handle a bit will straighten it out for another shot or two. Hard to describe, I will have to take some pictures next time. I am not using heavy ammo - only light ball (and the occasional 7N1). Any suggestions? |

Mabye the buffer isn't letting the bolt come far enough back for the secondary sear/disconnector to engage the hammer.
I'd cycle the bolt by hand with the top cover off so I could see inside to find out what is going on, unloaded of course. Ao if I'm right, the buffer may be a tad too thick. |
| You could probably try to some how cut the buffer a bit thinner. That might work. However, that buffer is probably going to come apart at some point and cause a catastrophic malfunction with chunks of rubber all over the inside of your rifle, or maybe one of the many other awful things that recoil buffers can cause to happen. My vote is to just get rid of that rifle and get another PSL. With your current one, it seems like you're having to choose between a gun that has serious malfunctions now without the buffer, or is going to have serious malfunctions later with the buffer. |

Recoil spring guide in conjunction with recoil spring (when compressed) is what keeps the carrier from popping out on backstroke. You may have too much play between guide and guide slots in the rear trunnion. I don't know what type of recoil guide PSL uses. Try telescoping recoil spring guide if current guide is wire type.

| It would really help if we knew what brand of buffer you were using since some are thicker than others. You may want to try switching to a blackjack brand buffer, it's one of the thinnest ones I've found and the least likely to cause any issues with your rifle. The Buffertech units are a bit too thick and in some rifles can cause feeding issues.YMMV |

It is a telescoping spring. It feels easier to work than my AK (converted Saiga).
I think it's a black jack buffer (I remember ordering a 2 buffer combo deal), but it's been so long I'm not sure. The one in my AK works fine. My PSL is a TGI/TG Knox. I hear they are not the best (and mine is proof). Anyone know where I can get a new spring? KVar and TGI don't have any. |

Another difference between the PSL and my Ak was the PSL bolt was sticky when rotating/locking in and out when closing or opening the action. I polished the bolt a bit and now it's much smoother like my AK. Perhaps this stickiness was contributing.
Also, with the buffer in working the action with the cover off there is no problem with the trigger assemby. Both hooks still catch the hammer. |

My advice for your situation as a fellow PSL owner is to do the following:
Trim buffer down to about half of its size or to the point where it will still keep the carrier group on track but allow for the maximum travel of the bolt carrier. Also grease the receiver rails. |

How are you pressing the trigger ?? If slowly then the problem could be an out of spec. disconnector. Some have too much material at the bottom front and hold the disconnector back a little further on the hammer, which means that the trigger may not always catch the hammer when the FCG resets and you get doubles or more.
You can try to simulate it by cocking the rifle and then as slowly as possible releasing the trigger to reset. Watch how the disconnector is holding the hammer and see if it releases before the trigger catches the hammer. If your hammer is dropping during trigger reset you have found your problem (disconnector). This tends to happen when your trying your best to squeeze off a round for the most accuracy, sometimes it doesn't happen when quickly pressing the trigger. |
