PTR44 Semi-Auto MP44

[Model]

This is my current PTR44 setup.
I am running a Stg44 op-rod/carrier with a new Recon bolt/ejector (top) my backup is the repaired op-rod/carrier with the original bolt and new Recon ejector.

44 bolt in PTR?

Pete, I thought an original Bolt would not fit in a PTR44 receiver? (to large)

Dave.

I was visiting with some guys at the Jefferson Barracks (Missouri) WW2 days last spring and had a chance to compare a rifle I built on a PTR44 rec. that's running original 44 parts with an unaltered PTR44 a guy had. He had his rifle field stripped and let me try my 44 carrier/bolt in his PTR. It dropped right in and locked up fine.
It's been said that PTR rec. have some metal added at the rear to preclude the use of a 44 bolt. The one I tried my parts in obviously did not.
Considering that neither a MP44 or PTR bolt have anything to do with the ability of a rifle to run full auto, I'd not worry about doing whatever I had to do to put an original MP44 bolt in a semi gun.
My rec. that came from Recon. had issues at the takedown pin area that required some repair/welding so I don't know if 44 pieces would have gone in it originally. That and the one I tried my parts in are the only 2 PTR rec. I have had a chance to examine. Could be some are different than others??

Hey, d dAY dOG

This question is for "d dAY dOG", I know you have fired many rounds through your PTR 44 with very few problems.
And I was curious to know, does your PTR 44 show the same wear as timdp`s and Mrfarb`s? (as pictured below)

 

[mrfarb]

I was thinking the same Rommel. I was thinking it may be associated with shooting blanks.

I don't believe so. I will look this weekend and post some pics - if I can find my camera. I would've notice that by now as I religiously clean the entire firearm after each days shooting session and soak it down all over with oil. I have only shot live ammo through it and mostly Prvi Partisan.

BTW: I DO NOT rapid fire this weapon. I've done that ONE time which was shortly after I bought it. I've notice an increase in jamming while rapid firing it. Don't know if that has helped me with longevity, but I only slow target shot this rifle. Just for interest, I'll see if I can post a video of me shooting it sometime and show you how the rifle functions better while pushing up on certain repro. mags. vs. not.

The mags. are repros. but have surface rust? Reenactor...? Dunno, but as always, it should be interesting to watch the results.


But this one being offered by Recon has been out for weeks and NO bites. Not surprising given the description though...

However, I did see a PTR44 sell for $9500 that was CA compliant with some good extras and work done on it by John Andrewski a while back...

Pump up the value !!!

Iv'e had the same issues with my Gun Rommel, after the Op-rod snapped it stretched the receiver in that very place, J.Andrewski and myself worked to get it back in shape. I do believe it is a weak point with all these (PTR44) rifles. Unfortunately the more one shoots it the more it will ware, its plane to see the steel is just too thin compared with an original Stg44.


p.s. I don't shoot blanks.

Just took it out shooting. Flawless!!!!

From looking at the pics of the issues with the PTR receiver and the carrier falling through the bottom, makes me think do the PTR receivers have the reinforcing steel in the bottom of the receivers like originals do? Seems that this would help keep the carrier from falling out the bottom.

Also anyone know where I can find a new MP44 barrel? US made preferred. Or know where I can get one made?
Thanks,
Kevin

Actually the area that is damaged is towards the front rather than the rear where the metal is doubled due to the overlap of the seam where it is spot welded.
If it would not create a interference problem with the trigger housing, the single thickness area could have a .063 thick piece welded over it and the clearance for the hammer milled to the minim to clear the hammer. Worth looking at maybe.

I made a MP44 barrel from a Mauser barrel. I wrote Tech Branch re that and a couple other MP44 related issues. Interestingly they deemed the much remachined Mauser barrel to still be a imported part. Good news was that they consider the piston, carrier and charging handle to be only ONE part re 922R.

Thanks Pete, was wondering about that "piston, carrier and charging handle to be only ONE part re 922R."

Updates.
Took the rifle out shortly after this discussion and it started jamming again after about two mags. Good thing I bring a G43 as a backup rifle...
The sides were not bulged, but it looks like the forward ears were worn more.

Got it home and hammered the forward ears quite a bit further down into the receiver so that the bottom of the bolt is skimming over the top of the ears and it worked well at a recent battle for at least 180 rounds. Will get a pic to see what is currently going on when I clean the rifle.

Tim

So we looked at the jamming problem a bit more and found that the problem is with metal deformation on the bottom of the receiver near the trigger group hinge point. Not visible in the photo are metal shavings from where the bolt was wearing on the receiver. Note the location of the bolt in the jammed position. From the top this corresponds to the front face of the bolt being halfway across the top of the mag with the round being halfway stripped from the mag.

In the photo below the side walls were bulged out a small amount at the points where the red arrows are. The bulge was flattened with a pair of angle jaw pliers with not serrated jaws. The two ears marked with green arrows here tapped down a bit with a brass punch. No idea how permanent this repair is but the gun did not jam once during a 30 round mag dump of blanks.

receiver problem

Like I posted earlier, welding a piece in then cutting out the area for the hammer to clear would probably be a permanent repair.

Yup, will probably end up doing that, but the next battle is two weeks away. Testing to destruction is always fun....;-)

WW2 weekend visit

I visited the WW2 weekend at Jefferson Barracks Saturday and had some good conversations with various participants. Gotta hand it to the guys bringing out all the vintage items for their fun and for us non reenactors to see. Good day Saturday with the 2 battles but really bad weather forcasts had many packing up late Saturday or early Sunday.

I sold the PTR44 with all the accessories and it was blank adapted with a bullet button to a guy near San Francisco who had to have it before January 1st. He was willing to pay almost anything for it so I just stopped at 9500 as I only paid 7500 for it.

Replacement Op Rod & Bolt

I purchased an original MP44 op rod and Recon Ord semi bolt from Jerry Prasser at Recon Ord. If everyone is correct, I hope to have little problems with my new PTR. I'll let everyone know what happens! Thank you all for your insight.

I would like to see an MKb42 and a first model FG42.

But, they need to be quality and they need to work. We also need spare parts, extractors etc.

I had my first PTR44 worked on 4 times by John Andrewski until Recon took it back. The second one, two times until, I put a modified original bolt and Oprod with compliant handle in it. Now it is perfect. But, it was two years of sending it off to gunsmiths to get it right.

They need to work and hold up to the demands of US shooters. I lived in Germany, hunted and shot at the German shooting clubs for 16 years when I was stationed there with the Army. I recall shooting my M1 Garand at the club, being required to load one round at a time. Well, not so in most places in the USA.

The guns need to function and be quality work.

Stg45 and make it work. Not something I have to send to the Gunsmith 3 or 4 times to work correctly.
