Description
The Tokarev TBP 12 Bullpup puts a full length 18.5 inch 12 gauge barrel into a gun twenty eight and a half inches long. That is the whole argument for the layout and this is one of the least expensive ways to buy it. Tokarev USA part number 21000128, flat dark earth, semi-automatic, magazine fed, five rounds plus one.
It arrives better equipped than the price suggests. Polymer flip-up back-up sights, Picatinny rail for an optic, a cheek riser compatible stock, three choke tubes and a five round magazine. The Tokarev TBP 12 Bullpup is a defensive and utility shotgun rather than a field gun, and it is built and priced accordingly.

What a semi auto bullpup 12 gauge layout actually buys you
The Tokarev TBP 12 Bullpup puts the action behind the trigger, which lets a full 18.5 inch barrel live inside a gun that is 28.5 inches long overall. A conventional semi-auto with the same barrel runs closer to 38 inches. That difference is the entire reason to own one: the same ballistics in something that turns inside a hallway, fits behind a seat and swings across a doorway without catching.
The trade is weight distribution. On an FDE bullpup shotgun 18.5 inch long in the barrel, seven pounds eleven ounces sits toward the shooter, which makes the gun feel heavier in the shoulder and lighter at the muzzle than you expect. Some people love it immediately and some never adjust. It is worth handling one before you commit, and we would rather you did.
Sights, rail and the cheek riser on an FDE bullpup shotgun 18.5 inch barrel
Polymer flip-up back-up iron sights are fitted, and there is Picatinny rail along the top for an optic. Sports South records the Tokarev TBP 12 Bullpup stock as cheek riser compatible, which matters on a bullpup more than on a conventional gun: get the optic height and the cheek height wrong and nothing lines up. Sort that out on day one rather than at the range.
Chokes and ammunition
Three choke tubes come with the Tokarev TBP 12 Bullpup, in the Benelli and Mobil pattern, so replacements are easy to source. Buckshot is where a gun like this lives. STARS 00 buckshot, nine pellets is the volume load and we hold it in enormous depth, Hornady Black eight-pellet 00 patterns tighter, and Winchester Super Match rifled slug covers anything that needs one projectile. The chamber takes 2-3/4 and 3 inch shells.
A magazine fed 12 gauge shotgun, and one thing to ask us about
A magazine fed 12 gauge shotgun needs magazines, and one five round magazine comes in the box. Tokarev states that the gun uses the industry standard T-1919 shotgun magazine pattern with capacities up to twenty rounds available. We would rather you asked us to confirm fitment on a specific magazine than take that on trust and buy the wrong thing, so ask before you order spares.
The rest of the Tokarev shotgun line
The TBP in urban camo is the same gun as the Tokarev TBP 12 Bullpup in a different finish. If the bullpup layout is not for you, the TSA12 and the TTS12 are conventional magazine fed semi-autos with the same 18.5 inch barrel, and the TSP12 is the pump action version for anyone who wants nothing that can fail to cycle.
Worth knowing before you buy
- 12 gauge is a SAAMI standardized chambering, so factory shells are consistent across brands. See the SAAMI published standards.
- A bullpup puts the ejection port beside your face. Left handed shooters should handle one before buying.
- The magazine standard is a manufacturer claim, not something our distributors document. Ask us before buying spares.
- Magazine fed semi-auto shotguns can be fussy about light target loads. Buy full power buckshot for anything that matters.
Buy the Tokarev TBP 12 Bullpup if you want a short, magazine fed 12 gauge for a hallway, a truck or a boat and you do not want to spend four figures getting one. It is not a clays gun and it is not a bird gun. It is a compact defensive shotgun that costs less than most people expect a bullpup to cost.
