As Original As it gets - This SLR-107UR rifle is an Arsenal, Inc. factory SBR in an authentic Krinkov configuration. Commanding all the benefits of a factory SBR such as holding a premium value, no additional markings, and factory warranty – the SLR-107UR rifle, chambered in 7.62x39mm, utilizes a short gas system and features a short-length 8.5-inch barrel. Built on a Bulgarian stamped receiver rifle that is built from all original brand new factory parts and premium quality US made components.

The furniture consists of black polymer ribbed handguards with a stainless steel heatshield that help protect your hands as well as 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.

This rifle has a 2 stage trigger and a scope rail for optics attachment and ships with a cleaning rod and one 30-round mil-spec Bulgarian Arsenal magazine.

Enjoy shooting at night with this rifle as it sports an authentic Krinkov Cone Design flash hider.

The SLR107UR 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 922r parts-source restrictions.

The SLR-107UR accepts any Bulgarian mil-spec double stack 7.62x39mm caliber magazine (M-47W, and M-47W40).

FIME Group Enhanced Fire Control Group
Includes FM-922EUS, the Enhanced Fire Control Group (FCG) for AK- and RPK-based rifles with stamped receivers. FIME's Enhanced FCG includes a single-hook trigger, hammer, disconnector, disconnector springs.
FIME’s Enhanced Fire Control Group delivers shortened trigger travel with an extremely smooth and light trigger pull. To prevent lever misfires, the disconnector face makes full contact with the hammer. Further, the disconnector is engineered with an elongated tail, which makes a full stop on the rear trigger guard rivet and the hammer stop prevents the hammer from slamming on the trigger. With these two designs functioning together, it eliminates the “trigger slap” found in competing products.

Note: All BATFE and NFA and Other Federal and Local Rules and Regulations Apply. NFA and Local Authority Approval may be Required Before any Modification can be made. Consult with NFA and Your Local Authorities before any Modification. Any SBR Modification Must Be Done By Class II Gunsmith. Any Modification to the Rifle Voids the factory warranty.
