The SLR-104FR is a Bulgarian 5.45 x 39 side folder. It’s unique in that it is the first Bulgarian factory made rifle to be offered in the United States.
The 5.45×39.5mm caliber SLR-104FR rifles feature a mil-spec stamped receiver, hammer-forged and chrome-lined barrel, and left-side folding polymer stock. The stock set is manufactured to the true original design and utilizes mil-spec reinforced polymer. The buttstock uses the standard 4.5mm pin that is interchangeable with other standard side-folding stocks with 4.5mm diameter pin holes. The side-mounted scope rail allows usage of many attachments that are designed for this type of rail, including Arsenal’s latest SM-13 scope mount. Arsenal uses its own US made fire control group with two-stage hammer and trigger that completely eliminates trigger slap and increases accuracy. The SLR-104FR has the standard 24×1.5mm right-hand threads with a removable muzzle brake. The stainless steel heat shield keeps your hand cool from the heat of the barrel. This rifle also features both a bayonet and accessory lugs on the front sight block and gas block. The SLR-104FR will be available in black stock set, desert sand stock set, and with left-side folding metal stock. Included in the rifle are one 30-round Bulgarian Arsenal Circle 10 magazine, sling, oil bottle, cleaning kit, and cleaning rod.
