Tokarev TBP-12

I’d probably use one of those notches,…you’re going to try and “punch” it counterclockwise (would probably work best with the receiver chucked in a vise).

I'll definitely try that out. Counterclockwise as if you were holding the gun and shooting correct? Surely they (Tokarev) wouldn't mean clockwise from staring down the barrel, right?
 
I went back and read every post. So I have to ask, why not try to call the company that either produced or distributed them to FFLs to see if they have a solution or even ask if you can ship it back for a factory repair. Because once you bang on it any warrenty that's available will be voided and you are likely to end up with an expensive paper weight! Just my 2 cents.
 
Spanner wrench sets are pretty cheap on places like Amazon. 15 bucks .

Hello gentlemen,
I'm revisiting this thread in an attempt to help the next poor soul that faces with this stuck barrel locking nut/weird spanner wrench size issue. I purchased a Tokarev TBP-12 on sale recently and totally stripped the gun down to parts to sand and paint the gun (it was a truly hideous paint job- black with technicolor paint splatter and white/gold honeycomb. YIKES. And to learn the inner working of the bullpup setup. The gun tore apart super easy until I got to that cursed barrel locking nut. As everyone else stated- in the youtube disassembly video published by Tokarev USA they only mention one hex head set screw. Mine had two. I tried to loosen the nut to no avail. it was TIGHT. The spanner wrench they give you is cheap stamped steel. The thing bent and the hooks snapped off first use.
My fix-
  1. Placed the barrel and receiver in a vice (obviously use wood or cardboard on the jaws so you don't damage the aluminum upper and don't tighten down too much).
  2. Used Rem Oil liberally around the barrel nut where it meets the receiver. Let sit for an hour then reapplied more oil. I'd imagine penetrating oil would have worked even better. Gently tapped around the nut for a minute or so with a soft mallet to work the lube down into the threads.
  3. Set the barrel and receiver in the vice horizontally and used a block of wood to stabilize underneath where the barrel meets the receiver.
  4. I used a Klein 1-1/4" Telescoping Basin Wrench (68232) and positioned so as to grab the opposite sides of the nut for the most even distribution of force. The long handle was a huge help as far as leverage. Slowly turned and the nut broke free!
After removing the nut, I found the culprit- overspray from that hideous paintjob got in the small threads of the receiver and acted like glue for the nut. Such a small oversight caused such a big headache!
Needless to say, I lubed the threads and didn't tighten quite so much upon reassembly. I've attached pics of the process and evidence of the carnage.

Anyways, I sent this to SDS Arms about the Tokarev TBP-12. When you go to TokarevUSA's website, the support link takes you to SDS Arms page for information and warranty.

In late October 2024, I bought my Tokarev TBP-12. I purchased it brand new in the Tokarev cardboard box, so never been fired. I took it to the range in early November just to put a couple rounds through it. With no round in chamber, I loaded the factory 5 round magazine. First round fired off fine, but the second round was a failure to feed. I unloaded the shotgun, reloaded the magazine back to 5 rounds, reinserted the magazine, and tried again. This time, I got two rounds off before the third ended in a failure to feed. I repeated the unloading and loading process again and was finally able to get off all 5 rounds without hiccups. I shot somewhere around 15 rounds total from the shotgun that trip and brought it home to clean and put in my safe. Upon cleaning, I had read that occasionally the barrel locking nut can be torqued too tightly from the factory. I figured it wouldn't be a problem since Tokarev sends a spanner wrench from the factory for this purpose. However, when I started the disassembly (great video by the way...on Tokarev's official youtube page really helped out), the barrel locking nut broke the tooth on the spanner wrench. Without a proper tool, I couldn't get it off, so I cleaned what I could and then I put it away. Fast forward to April 2025, I started looking to sell it to purchase the TAR-12 (the mag release was a little too far back to be able to keep the weapon trained on target and change mags unless you're a lefty). My dad (a lefty) offered to buy it for the cost of the TAR-12 and came into town to test it out. We took it back to the range and were only able to fire off 2 rounds total. Both were failures to extract. He told me once it's fixed, he'll still purchase it, but it's got me wondering if there's something more serious going on with the shotgun. I'm averaging 1 malfunction every 4 shots, and I don't really want to take it back to the range just for another subpar performance. That said, I have a few questions.

1) The ammo I used was Sellier & Ballot SB12BSF 2-3/4" Buckshot 1214fps, from the same box both range trips. Is there an issue with the ammo type I'm using as far as velocity or size? I know ammo can lead to a lot of unwanted malfunctions.

2) Is there any way you all could send another spanner wrench since it broke on first use or tell me where I can buy one so I can full breakdown the shotgun to clean? I know there shouldn't be a huge issue with cleaning at this point considering only 18 rounds have been fired from the shotgun, but I'd still like the ability to clean the whole shotgun and not just the exterior components.

3) What are the odds the shotgun is just a lemon? I really do enjoy the shotgun. It looks great, and when it works, it feels great to shoot and is easy on the shoulder.

Thank you for your time. I really do want to like the performance of this "product", but at this point, it just looks nice in pictures and it's a nice "talking point".


Has anyone had any similar experiences with this gun? Any helpful thoughts or insight would be greatly appreciated. Thank you.

All these 12ga shotguns working blow back semi-autos need 1300 fps or more to feed properly. I have several AR12, Panzer Bull Pup and I just ordered one like yours on sale, minutes ago.

I had the same issues you did with my first Panzer, failure to feed, all I shoot is 00 or slugs, I shoot Sellier & Ballot, reliable stuff, but it has to be 1300 or more to feed reliably. ;)
