The Tokarev TAR-12MP AR platform semi-automatic shotgun uses a conventional gas-operated action which is located around the support tube that runs below the barrel. The return spring is also located around the same support tube which is concealed by an enlarged polymer handguard. The AR12 barrel can be very easily removed from the upper receiver. The upper receiver is manufactured from an aluminum alloy while the lower receiver, pistol grip, and stock are manufactured as one piece from impact-resistant polymer. The AR-12 comes with one 5-round metal detachable magazine. The magazine release button mimics the M16 rifle location. The manual safety also duplicates the M16 style being located on the left side of the receiver above the pistol grip. The top of the receiver has an integral Picatinny rail for mounting rear sights or any optical accessories. The AR-12 12-gauge shotgun is appropriate for all levels of hunting and sporting enthusiasts. Comes packaged in a nice commercial box with 1 mag and a manual as seen above. Includes removable front and rear flip-up sights. Chambered for 2 3/4" or 3" Magnum loads. These are just really cool. Note - The Tokarev TAR12P accepts all standard AR-12 / MKA-12 - FR-99 pattern shotgun mags and drums. This is the MP model meaning that is features the highly popular marine grade nickel finish.
