WE-Tech's REX models of GBB pistols brings new innovation to an already established line of Hi-CAPA style designs. The REX line features a more ergonomic, redesigned grip with simulated stippling, improving the shooter's grip. The REX line utilizes CNC finishing to ensure reliable fitment and improved performance. The REX line also utilizes a stronger recoil spring and short stroke buffer to give the guns a more realistic recoil and improved cyclic rate. With a variety of designs and barrel lengths, the REX line of GBB pistols will perform greatly and look to part in any Airsoft scenario.
