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.

Manufacturer: WE-Tech

FPS Range: 300-330

The Best Brand for GBB Beginners; WE-Tech Airsoft!

*GBB 101: It is a good idea to let your magazine return to regular temperature before using it again for optimized performance. We recommend spare magazines for best performance on all GBB's.

"Got this at a airsoft auction for very cheap and it is so unbelievably reliable and effective, as well as also just being bad ass. The only downside is with the actual green gas, as sometimes green gas is not the most reliable, but that doesn't take away from the actual pistol. Very great gun would recommend a lot especially for first time airsofters, to have a reliable, effective, and just genuinely badass gun.

"this is my very first pistol and it works great my only issue is the website doesnt say what thread size the barrel is but the actual pistol IS AMAZING the amount of mods you can put on this is great the reliability is even better and i can say its probably the best pistol i own (i own about 5-7 now)
