REX Alpha – Competition Ready Pistol

Vepr 12 Shotguns – Get ’em before they’re gone!

Tactical Compact – Available in Black, FDE, and Grey

Rex Firearms has expanded its existing line of high-quality pistols by introducing the REX Zero 1 Tactical Compact. The standard REX Zero 1 Tactical pistol has been a favorite amongst consumers due to its renowned reliability and the fact that it comes from the factory ROR (Rex Optics Ready). The new REX Zero 1 Tactical Compact offers the convenience of a smaller handgun without compromising firepower, reliability or the popular ROR features. By combining all of the benefits of the REX Zero 1 Tactical in a smaller, compact package, Rex Firearms have once again hit the mark.


The REX Zero 1 Tactical Compact comes loaded with features such as a hard anodized aluminum frame, nitrocarburized steel slide made from a solid bar stock, forward cocking serrations, 1 piece cold hammer forged barrel, a short accessory picatinny rail, an ambidextrous safety and magazine release, de-cocker, 1/2×28 threaded barrel, suppressor height sights, 4 plates for optics mounting, a hard polymer case, (1) 15 round and (1) 17 round magazine, and more.

The Tactical Compact is currently available in three different colors. Please see below and click on each photo to learn more.
