TRG-22 Bolt removal problem

[ronas]

I was dry firing my TRG and it got to the point bolt is very difficult to cycle. Please see photos of bolt end with extractor. I'm thinking something is not right there.

Any help would be greatly appreciated.

Well I put in spare firing pin and it works fine. Could not tell old firing pin was bent.

So the question is does dry firing these rifle ruin firing pin?

Check the camming surface on the back/underside of the bolt housing and firing pin. Make sure there are no burrs or dirt and grime in there. I had the same issue and cleaning this area helped out a lot!

Have you recently adjusted your trigger?

+1 on the camping surface, when i first got mine i dry fired a bunch and the bolt lift started to get gritty and stiff, I cleaned and lube the camping surface and its smoothed right up.

Well it stopped cycling again with the new firing pin. Now what?

Yes, but I have the trigger group removed and I'm still having the problem.

To clarify I should say bolt slides to battery easiy, then bolt is hard to lift, once lifted it slides back with no problem.

I would not reccomed dry firing without a snap cap. I either read in the manual or on a thread hear many years ago that it causes problems with the firing pin.

Didn't find anything in the manual.

Ronas, +1 one on the camming surface. I had to smooth out the camming surface on mine as well too when it was new. take it apart and polish that area. Trust me I never had a problem again dry or firing the rifle again. You think you would not have to do that to a 3000.00 rifle but I did.

Re: TRG-22 Bolt removal problem

With some hesitation I can say I think I found the problem and fixed it. When I put in new firing pin it worked fine for a very little while, so I think the firing pin or it's associated assembly was the problem.

So I dissembled the entire fireing pin assembly and clean it with powder blast, then I oil the parts of the firing pin and assembly I could get to, for the part i could not get to I applied my favoriate lube and then blew it out with high pressure air leaving a light coating of lube inside.

For right now it works perfectly, how long not sure. Plan is to put trigger group in rifle and dry fire the heck out of it with a snap cap.

Glad you got it figured out!! The TRG is a great platform but like anything mechanical, it has it's issues.

Re: TRG-22 Bolt removal problem

I dry fired mine when I brought it home and found it was not lubed and made a burr. Took it apart, cleaned, polished and lubed. Thousands of dry fires later I have not had a single problem. I do inspect the firing after every 1k or so hammer drops just to check. Also the manual says dry firing is ok. From what I understand there have been rumors of brittle firing pins in the Sako's.... I plan on finding out if that is true or not, I dry fire/shoot in COLD and HOT weather (~10* F - 105*F).
