Limited Edition

This SLR-104UR rifle is an Arsenal, Inc. exclusive, limited production item. We've created this custom configuration by combining a factory SLR-104UR SBR with the NEW Arsenal Gambit barrel extension!

The Arsenal SLR-104UR rifle, chambered in 5.45x39mm, utilizes a short gas system and features  a Bulgarian stamped receiver. This limited edition features the ALL NEW Gambit - which is a barrel extension featuring an aggressive profile and serves as a flash hider/muzzle brake. Chrome lined and made of hardened steel, the ALL NEW Gambit enhances your shooting experience by providing reduced recoil and muzzle rise.  

The furniture consists of a Soviet style pistol grip and left-side folding stock with a cleaning kit compartment. The stock also features a button that engages the front latch assembly, ensuring rapid deployment. 

The SLR104UR is constructed of all new manufactured parts made in both Bulgaria and the U.S. This firearm is fully compliant with Title 18 USC Section 922(r) parts-source restrictions.

Ships with one 30 round magazine.
