| Picked up a barely used PTR-91 and am having trouble getting the bolt to fully close. Finally got it to fire by manually loading the breech, slapping the bolt closed then inserting a loaded mag. Fired about 5 rounds then another failure to go into battery. So do I need a new recoil spring or what? |

Not super familiar with those kinds of rifles but i'd start by giving it a good cleaning, especially the chamber. I think you could use a .45 caliber brush in the chamber.
Next thing I'd look into is getting new mags. These are cheap right now so buy as many as you can afford. |

| Not all PTR 91s are the same. I have 2 PTR 91 GIs and they run great. I have seen older PTR 91s with issues - newer ones since they went to deeper flutes - not so much. The only issues I have had is low bolt gap .013" on a new rifle and loading a mag with bolt closed and not having it strip the 1st round when cocking it, but that might be the system. I have notice my trigger pull is not heavy as older PTR91s, SAR 8s, and HKs I have shot at the range. Also, the 1st thing I do when getting a G3 type rifle is install a new HK locking piece from Robert RTG and I notice the bolt gap improves and the gradual loss over the next 1000 rounds is .002" or less. |
