EXTAR EXP-556 Complete Specs and Full Gun Specifications

These pistols are a lot of fun to shoot and hold up extremely well. The polymer upper/lower make the gun light enough to shoot like a regular handgun, and the muzzle break mitigates any recoil/rise while releasing a hell of a ball of fire and a pretty damn big boom. It's an attention getter for sure. The Mk1 is the original pistol, the Mk2 adds a rear rail to mount an SBR stock or a pistol brace, and a full-length rail for optics.
