BOLT brings to the market the officially licensed Knight's Armament Co "KAC" SR16 URX3.1 Full Metal Airsoft Rifle along with BOLT's patented blowback Bolt Recoil Shock System (BRSS). It's shock system is one of the best non gas-powered blowback features for any airsoft rifle on the market, period. The BRSS is superior to fake blowback systems that bleed air out of the cylinder and move a small metal slide to give the appearance of blowback, but lack the much sought after kick many realism and milsim players look for. BOLT took painstaking efforts to make the recoil system as energy efficient as possible which keeps you in the game longer than less efficient blowback rifles.  Designed to be Tokyo Marui parts compatible, this gun is also over 90% internally upgradable for the hardcore airsoft techs out there. 

The Knight's Armament Licensed URX3.1 rail system offers a superior rail system for mounting any and all accessories an operator may need: Lights, lasers, grips, pressure switches, PEQ boxes, cameras, and more. With integrated QD sling mounts as well as removable and relocatable tri-panel handguards, this rail is extremely functional, comfortable, and lightweight. Whether you run is loaded with mission-critical accessories or completely slick, the URX3.1 rail system is designed to be the perfect all-around RIS system. Mounted atop the monolithic upper picatinny/weaver rail are a set of tip-up SCAR-style iron sights that can be easily detached or used in conjunction with other aftermarket optics such as red dots, holographics, or scopes. 

Internally, BOLT features it's TM-compatible gearbox and patented BOLT Recoil Shock System. This Version 2 gearbox houses a steel, powder metallurgy gearset and M120 spring. Thicker gauge wiring lends LiPO-ready compatibility to the gun as well. A BOLT BM300T long-type high-torque motor keeps the gun firing fast from the first shot to the last. Aluminum piston with full metal teeth as well as an aluminum piston head make for an extremely durable and long-lasting compression system.
