A shotgun ammunition conversion system has a detachable magazine well having a sleeve defining a rectangular passage adapted to removably receive an ammunition magazine, a boss extending forward of the sleeve and at a level above at least a portion of the sleeve, the boss being adapted to be received in the rear aperture of the magazine tube, and a tang extending rearward of the sleeve and defining a tang aperture operable to receive a fastener associated with a shotgun frame to secure the magazine well to the shotgun with the sleeve proximate and aligned with the loading port when the boss is received in the rear aperture of the magazine tube. The boss may have a lower cylindrical surface portion operable to contact a lower portion of the magazine tube adjacent to the rear aperture. The boss may be a cylindrical body.

The disclosed magazine cap choke adapter allows a user to store an extra choke in place of the shotgun magazine cap. The magazine cap choke adapter is formed from a body that includes a first female threaded end, or proximal end, that threads onto the magazine adapter of the shotgun. Moving away from the proximal end, the magazine cap choke adapter tapers to a second female threaded end, or distal end, into which a choke is optionally threaded.

A semiautomatic shotgun comprising a receiver, a barrel, a forward gas block assembly attached to the barrel, a slider assembly rearward of the gas block assembly extending into the receiver. Upon firing a shotshell the explosive gases in the barrel are diverted through two ports into the gas block assembly, specifically into a pair of lateral pressure relief valves positioned on both sides of the barrel. The pressure relief valves further having a gas pathway from the barrel provided by clusters of holes less than a specific size and on-center with the barrel axis. A piston is forced rearwardly and engages a slider of the slider assembly that is linked to a breech block in the receiver. The breech block loads unfired shells and ejects the fired shells accomplishing the semiautomatic recycling. The dual pressure relief valves actuate to moderate and limit the gas pressure that enters the piston chamber when using shotshells of different power levels thereby providing consistency in the recycling operation. The shotgun assembled with a plurality of retention pins having uniformly sized O-rings.

The present invention relates to a magazine extension which has been developed for use in semi-automatic and pump-action hunting rifles and which increases the magazine capacity without losing spring force by easily connecting the end of the rifle to the magazine tube.
