Army Armament R501 GBB Airsoft Pistol, Black

Topped with a CNC-machined metal slide, outer barrel, and ambidextrous safeties over a polymer lower frame, the Army Armament R501 GBB Airsoft Pistol uses a solid internal hammer system. Pre-stippled grips, a functional beavertail safety, and an under-barrel accessory rail ensure comfortable, secure control in the field. Clocking in at 222mm long and weighing 1.02kg, this semi-auto sidearm fires 0.20g 6mm BBs at 300–320 FPS using green gas. It comes standard with an adjustable hop-up chamber, a flush 28-round metal gas magazine, and a user manual.

Compatible with standard Tokyo Marui Hi-Capa parts, this airsoft sidearm takes drop-in TM-spec barrels, buckings, recoil springs, and triggers. Recommended performance upgrades include installing a 6.03mm tightbore inner barrel for tighter groupings, dropping in a soft 60-degree silicone hop-up bucking for extra range, and swapping to a lightweight aluminum blowback housing to boost cycle speed and gas efficiency.
