Built in Bulgaria and imported by Arsenal Las Vegas, the SLR-104FR follows the AK-74 pattern with a 1 mm stamped sheet-steel receiver and smooth AK-74/100-series top cover. Import and origin markings include Arsenal LAS VEGAS, NEV U.S.A., and Made in Bulgaria. This model accepts standard AK-74-pattern 5.45x39 detachable box magazines.
The 16-inch barrel is cold hammer-forged, chrome-lined, and threaded 24x1.5 mm RH. It is fitted with the AK-74 pattern two-chamber muzzle brake with detent, and uses the 90-degree AK-74 gas block. The excellent bore condition with sharp rifling supports precise, consistent performance.
The left-side folding polymer stock uses the 4.5 mm hinge and features a release/locking button at the hinge on the left rear of the receiver, plus a left-side sling loop. Length of pull is 13.5 inches. Overall length is approximately 36.875 inches unfolded and 27.375 inches folded. Unloaded weight is about 7.4 pounds (no magazine), offering a balanced, handy configuration.
Sighting is via a protected post front sight and a sliding tangent leaf rear sight graduated to 1,000 meters. A factory left-side optic side rail on the receiver provides a solid mount interface for compatible side-rail optics. The rifle operates with a semi-automatic, long-stroke gas piston, rotating bolt system.
This example features an installed ALG trigger for a cleaner, quicker break. The lower handguard is US-marked and includes a stainless-steel heat shield. The SLR-104 series was introduced in 2014 and discontinued in 2017, making complete, well-kept rifles with quality upgrades and factory features like this one particularly notable.
