These complete stock sets, manufactured from high-strength reinforced polymer, enhance the look of AK-pattern rifles, while providing the rugged performance, extreme weather resistance and solid feel that are all hallmarks of the Arsenal, Inc. rifle lineup. They meet and exceed all mil-spec requirements. They are available in matte black, plum, OD green, and desert sand colors. The Warsaw (short) length buttstock (12.625" length of pull) includes a trapdoor for a compartment for an AK-pattern cleaning kit, high-strength hardened steel ribbed butt plate, as well as a steel, anti-bind sling swivel. The pistol grip follows the original Russian AK-74 pattern and includes a metal reinforcement. The lower handguard incorporates a stainless steel heat shield and metal insert, resulting in decreased heat transfer and maximum user comfort during long shooting sessions. This stock set fits all stamped receiver rifles of AKM and AK-74 variants, including SGL21, SGL31, and SLR-105 rifles. These are the only US made mil-spec stock sets in the market that are also 922r compliant.
