Umarex Glock 17 Gen5 MOS BB Gun

Set your sights on the GLOCK 17 Gen 5 MOS ready (Modular Optic System) blowback BB pistol. Optics ready to accept your favorite pistol-style reflex sight this MOS GLOCK 17 features the latest in GLOCK design innovation found in the Gen 5 iteration. Powered by a single 12 gram CO2 cartridge that easily loads into its drop free magazine that also holds 18 rounds of steel BBs this blowback action (moving slide) GLOCK sends BBs downrange at 370 FPS with or without an optic mounted to the slide. Likewise you can fit a light or laser to the accessory rail forward of the trigger guard. To keep your GLOCK CO2 pistols running smooth put a drop of silicone oil like RWS Chamber Lube on the tip of each CO2 cartridge when you install it. And remember to remove the cartridge after each shooting session. Leaving it with a charge in the magazine can drastically reduce the life of the seal.
