My rifle is in the aw-8xxx range of possibly having a bad trunnion according to the ptr-91 website.
Out of the box brand new I used my feeler gauge and found it had a .014 bolt gap out of the box.
I finally got a chance to shoot the rifle on Saturday to see if I had a bad trunnion. I shot 240 rounds of
federal 150 grain fmj to test it out. I didn't have one problem with the rifle, however; when I got home
I checked my bolt gap and it had diminished to .007 on my feeler gauge. I inspected the trunnion and it
didn't look like it had any cracks, however; it must be a soft trunnion. Only 240 rounds through the rifle and my
bolt gap shrunk from .014 to .007 in one day. I'm hoping PTR-91 will uphold their
side of the warranty and fix this issue. It sucks that we have to go through this considering the amount of
money we invested in buying their product. I'm not sure if I have to pay out of my own pocket to ship and
they refund me or not.
Side notes, the metal handguard gets really hot to touch after 60-80 rounds. I'll make a note to wear gloves next time.
Also, the rifle is really heavy to shoot unsupported/offhand. I would get to about 5 rounds and I felt my arm starting to
shake a lot. This might be my technique, however; I could definately feel the weight.

I know it sucks but from what I have heard, PTR will stand behind their product.

I decided not to buy a couple of PTR PDWs when the trunion fiasco came about. I changed my mind when I saw that they publicly acknowledged the issue and stated they will fix any defective rifles.

If the trunnion isn't cracked, try Replacing the BOLT HEAD ASSEMBLY.
My GI dropped from .018"to below .006" in a couple hundred rounds. Turns out the US/PTR made Bolt Head Assembly was made too soft.
They HAVE had heat treating troubles in the past and, obviously, continue to have them. The guns are nice once good parts are put in.
You could see severe wear on the Locking Piece without any magnification. Quite obvious when compared with a GOOD, German/Contract built set.
I put a HK Bolt Head and Locking Piece in and after 1300 rounds it is STILL above .018".
Go with a German OR Contractor built set, NOT the US/PTR stuff/parts. Just for good measure, I also put a German Semi-Auto trigger pack in from RTG.
Gun is now doing GREAT!! (It ALWAYS shot really well and was above average in accuracy IMO).

+1 allday long in agreement with BANGER. Unfortunately,I have known this for some time now. I have to JLD built weapons with german/euro bolt parts and bolt gap has not budged after 2,000 rnds, not to mention they run FLAWLESS and super accurate with the Wilson & TC barrels. Try to find an older JLD built rifle if you can.

PTR offers a warranty which you have indicated you know about. Don't muck it up by working on the gun on your own. You'll be potentially wasting money and voiding the warranty at the same time without fixing anything. My advice is to leave it be and send it directly to PTR.

Ya, thats a very significant BG loss. I,m sure they will either fix or probably send you a NEW rifle.

Very good to hear, I'm glad you made this choice. We will be watching to see how it turns out for you. Do us all a favor, when you update about your rifle, do it in this thread instead of starting another. Go advanced and update the subject line to include the word "update". Makes things easier to track and all the history of your gun will be in one place for searchers to find.

My faith level in PTR was really NOT GOOD and I wasn't too happy with their attitude on phone calls either.
I have since revamped my thinking and would readily send rifle(S) back for them to repair since their return policy/warranty is so good (and Grandfathers, too)!!
Thank you for listening to your customer base, PTR!!
LONG MAY YOU PROSPER!!

I got back my rifle today from PTR. The letter in the box said they replaced the bolt head and the buffer. I checked the bolt gap and it is up to .015 now. Earlier in my post I mentioned the bolt gap fell from NIB .014 to .007 after 240 rounds. I'll update again as soon as I can put another 200 rounds through. Lastly, PTR does honor their lifetime warranty and was prompt on answering my e-mails to get this expedited.
