Built on a stamped AK-pattern receiver with a smooth top cover, this KR-103 retains the proven long-stroke gas system and right-side charging handle. It uses standard AK-pattern iron sights with a front sight post and a tangent rear leaf. The 16.3 in barrel is chambered in 7.62x39 and is threaded 24x1.5 mm RH.
The rifle is outfitted with an extended aluminum M-LOK handguard and a railed gas tube, adding usable rail space and modern accessory mounting. The handguard assembly includes an integral bottom rail section with a small hand stop, and the handguard block bears the M-LOK "M" symbol along with a "1064" marking.
An AK Master Mount side-rail optic mount is installed and marked with Patent No. 10955221; it provides a full-length Picatinny rail that bridges over the receiver. An Echo Nine Three V3/QD sling plate is also installed for flexible sling attachment.
A skeletonized metal side-folding stock brings a compact storage profile with a listed length of pull of 13.0 in. At the muzzle, a cylindrical brake/booster is installed on the front-sight-base–mounted threads; the OEM muzzle brake is included. The package is rounded out with the original polymer furniture set, the factory case, manual, and one 20-round magazine.
