What ammo were you using? Not that I think it's the cause of your problem just curious

 

I was just thinking of that. Wal-Mart MKE 308 and LC 63.

 

I've fired 100 rounds through a virgin PTR-91 GI, all of it the MKE "ZQI" 7.62 NATO from Wal-Mart, with 100% reliability.

Not much of a test, but the rounds seemed to shoot well in my particular gun. I've got several hundred more rounds of the same ammo waiting to be shot through it as well.

 

I have a junk made parts kit that shot 80 rounds without a problem but this NEW RIFLE right of the box did not even shoot 2 rounds without misfiring. And that was after I cleaned the large amount of oil coating everything.

 

There have been a good deal of these threads lately that i hAve seen in the past few weeks. Maybe it is due to PTR moving manufacturing plants as there are always isues to be worked out. You mentioned marks on the bolt face, I would check to make sure there are no burs around or in the firing pin hole.

 

There on the right side of the bolt face there the corners that have have been rounded off and now are sharp.

 

Do you have any pictures of the bolt face?

I had light primer strikes for the first 100 rounds of my brand new PTR GI, but after the "break-in" period of around 100 rounds (brown bear 145gr .308 lol), it functions flawlessly now. At first, everything on the rifle was extremely tight fitting. Not sure what's going on with your bolt, but PTR customer service seems to be top notch.

Personally, I would just shoot the sh*t out of it up until the 100-150 round mark and see if the issues go away.

 

If you did the gap tests right then that amount of loss is, IMO excessive. Give us pics, please and definitely look for debris after breaking it down

 

My brain tells me to say that you should look close at the trunnion for signs of marks where the bolt face seats. A bolt gap difference of .004 could be something (brass shavings or something) at the trunnion preventing the bolt from coming forward enough. Could be a fleck of steel or some MFG slag that is marking the bolt face.

 

Well today I called PTR and they said for me to take a wire brush and solvent and clean the chamber really well. When I got home from work I did just that and then disassembled the bolt carrier group and cleaned it as well. I double checked and it was .020. So I grab a couple of mags and went out the back door. My rifle is now a single shot. I will try to get pics of the bolt. But on Monday I am going to call again and send it to them. I really want this to be reliable.

 

Did you purchase the gun online or the LGS? If you have to send it in let us know what PTR told you the turn around time would be.

 

With what ammo? That's a bummer that it's not running. Please keep us updated on your situation. If they give you the run around we would like to know.

 

The ammo is was using was Turkish mke, LC 63 and some hunting ammo.

 

I bought the rifle from atlantic firearms. They put it up for sale and I borrowed some money to buy it. They shipped pretty fast and I got it with a plastic rifle case and 3 mags. I can't complain about the rifle other than it does not shoot like it's intended to. I will let you know what PTR says about how long it takes.

 

I would check with ATLANTIC FIREARMS before doing anything drastic. The person to contact is Matt Busan. See if they can help or have any ideas. I had a similar problem and they jumped all over it!

 

I could try that as well but at PTR I talked to Chris P. and he gave me his extension if I had to call him back if I needed to send it to them for repair.

 

Check to make sure both the rollers aren't locking up when they shouldn't. I had my first hiccup while testing some steel case and noticed towards the end of my shooting session I was getting one or two rounds per mag with light primer strikes. I put about 160 rounds of zqi ammo down range fine then switched to tula steel case and after 60 or 70 rounds I'd get a light primer strike eject the round then get a few more rounds off then click nuthin. I dissembled it and found the right side of the bolt the roller was gummed up and locked up why the other side moved freely. I cleaned the rifle and found out i put to much oil on the bolt last time I cleaned it that the powder would gum up the roller so this time I had used little oil on the bolt and what do you know worked flawlessly for 100 or so rounds I had left of steel case. Ill be back out in a few weeks to try out some wolf steel first then back to shooting brass. The right side of the bolt meaning the opposite side of the charging handle the bolt roller wasn't rolling freely and had a hard time moving. Thought this might help but if not might help someone with the same issue.

 

When I sent my PTR in, they tell you the long wait just in case. Mine was repaired and turned around in 10 days start to finish.

None of this sounds right so personally I would just send it back and let it be handled under warranty.

 

Me to.

It might take a while, but they SHOULD fix it. If you get it back and it's still broken, demand a refund.

 

Well they might fix it before another legendary name change hopefully. Before you send it back, see if you can discreetly mark parts. That way you can tell what was replaced when you get it back. Not all companies include a copy of the work order.

 

I will do that. Thanks

 

I'm pretty sure they'll take care of you though.

 

Cool. Well all should be well then. I just don't understand why they had the original parts and knew they were going to run out one day, they didn't figure out how to make them identical. If everything was 100% in spec, the gun would run.

 

CAMMOSTUD , Please email our office about this , We will be more than glad to work with you & PTR to get you back up and shooting very quickly . Typically if there is a legitimate issue right out of the box we will simply send a emplacement gun out so you do not have to wait. Email >>> sales@atlanticfirearms.com

 

Class act.. have bought from you before, and will again

 

Bam! That is fantastic customer service right out the gate! You guys just got my business come tax season!

 

I feel your pain. My PTR is still failing me at an epic level. I cleaned the hell outta the gun and ran AE 150gr .308 and out of 40 rounds had 3 fails. After calling PTR they said to clean it and run steel cased in it.... Well seriously? I have cleaned the hell outta the gun each time and it has failed to run everything. 4 different types of ammo. Im about to just sell the dang thing and buy an AR10 type. It seems like there are 5 different people here with the same issues. Im just tired of it, 290 rounds with 43 failures.

 

I have similar problem. I bought a PTR91 GI from atlantic firearm and currently ran through 280 rounds. You have 290 rounds with 43 failures, but I have like 9 out of 20. Pretty much a single shot rifle.
I tried various kinds of ammo, including PMC and tula (.308); Federal American Eagle, Federal white box, and Winchester (7.62x51).
During last range visit, 3 boxes of 7.62x51 yielded 7, 7, 5 misfires out of 20 rounds; 3 boxes of PMC .308 yielded 9, 6, 4 misfires out of 20. It looks like my 91 is improving but still......I don't know if I should sent it back to PTR.

 

I'm sorry to hear that so many of you are having issues with your brand new GI models. This is now making me think that it's possibly a batch issue? It's a pretty simple platform/design so there couldn't be too many variables, right?

My failures were only limited to light primer strikes in the 1st 100 rounds. I stopped using so much TW25B and switched to a med oil and all my issues went away.

I don't mean to poke into the problems here, but what exactly is happening when you guys are saying that the rifle is single-shot?

Insert magazine > Chamber a round > fire.... does the action eject the spent casing and load a fresh cartridge? If it did strip a new round, was the bolt fully closed and into battery? Light primer strike? just curious...

 

Why doesn't PTR try to defend their product on this forum? They are the ones who built the guns. Why does ATLANTIC FIREARMS have to be the who always steps in to save the day? They just sell us the firearms. :wink:

 

My rifle has acted like a single shot a few times... Basically what i mean by single shot is that I load a magazine, chamber a round, fire the round, then CLICK!, I pull back the charging handle and eject the round that didnt fire then chamber a new round, gun fires new round and then again CLICK! Acting like a bolt gun cause i have to manually cycle the action each time haha.

It has got to be a bad batch problem, because most of the rifles are the GI-R, and it looks like most of them have been bought in the last month also and all from atlantic firearms. Also most of the people with issues have fired different types of ammo.

I wanna like the gun, but get pissed when I look like a jack ass in front of my buddies because my rifle wont operate properly. Especially after I told them It was supposed to be a "reliable HK clone".

 

Did you notice light primer strikes on the manually ejected rounds?

 

Really considering selling it and putting the money towards an actual HK.
