Arsenal, Inc.'s upper and lower handguard set is constructed of high-strength reinforced polymer and offers a modern, weather resistant upgrade over typical AK-pattern wooden components. The lower handguard incorporates a stainless steel heat shield and metal insert, meeting and exceeding the mil-spec requirements. This results in decreased heat transfer and maximum user comfort during long shooting sessions. They come in matte black, plum, OD green, and desert sand colors, and will fit any stamped receiver rifles, including AKM, AK-74, AK-100 Series, SGL21, SGL31, SLR-104, SLR-106, and SLR-107 rifles. These are the only US made mil-spec handguards in the market that are also 922r compliant.
