KWA factory original standard H&K USP 25-round gas magazine, for the KWA H&K USP gas blowback pistol. Durable metal construction with reinforced feed nozzle. Please note that the USP Tactical, Compact, Match, and SOCOM all use UNIQUE MAGAZINES. However, this standard USP magazine WILL fit and function with KWA USP, MATCH, and SOCOM models (although the base of the mag will look different from the original MATCH/SOCOM mags). This magazine is the OEM mag for the standard H&K USP (KWA PART #101-00521).
NOTE: DO NOT USE PROPANE, RED GAS, or HFC 134a Gas with this KWA product. Using propane with this KWA Gas Blowback will void the manufacturer's warranty, and can cause irreparable damage to the rifle.
