Poseidon CSI XG8 Close Combat Tactical Gas Blowback Airsoft Pistol, Black/Tan

Poseidon's CSI XG8 Close Combat Tactical GBB is a gas blowback airsoft pistol built for realistic manual of arms and compact carry. It runs on green gas or CO2, delivering 380–410 FPS with 0.20g BBs. The metal alloy slide, outer barrel and blowback internals pair with a high-impact polymer frame for durability. A slide-concealed fire selector lets you switch between semi and full-auto without removing your hand from the grip.

The proprietary GBB internal system differs from standard Tokyo Marui or WE designs, so internal components like gears and pistons are not interchangeable with those platforms. It does accept standard GBB inner barrels and buckings for hop-up tuning. The pistol ships with a 25-round gas magazine, an aluminum muzzle protector, an 11mm CW to 14mm CCW thread adapter for flash hiders or mock suppressors, and a removable top Picatinny rail mount kit. An under-barrel rail takes tactical lights, and the RMR-footprint optic mount allows red dot sights without a separate plate. This model is Canada compliant and features a two-tone finish.
