MasterPiece Arms MPA 5.7x28mm 20-Rd Black Polymer Pistol Magazine

The MasterPiece Arms MPA5770 magazine is a factory 20-round replacement magazine purpose-built for the MPA Defender pistol chambered in 5.7x28mm. Whether you need a spare for the range bag or a fresh replacement for a worn mag, this unit drops in and feeds the same way the original equipment does.

Constructed from durable black polymer, the MPA5770 keeps carry weight down while standing up to regular range sessions. The generous 20-round capacity extends time between reloads, and the factory profile ensures proper seating and reliable feeding with any MasterPiece Arms Defender-pattern pistol. If you run an MPA Defender, this is the magazine that matches the gun it ships with.
