Arsenal AK-140S Features The Arsenal AK-140S is a US-made muzzle brake built for AK-47 rifles chambered in 7.62 X 39 styled after the classic AK-74 muzzle device design. It attaches directly to the front sight block using 24x1.5mm right-hand threads matching the factory thread pattern found on AK-pattern rifles without requiring an adapter. The one-piece half-moon design redirects propellant gases to reduce felt recoil and control muzzle rise helping shooters stay on target through rapid strings of fire. This design closely mirrors the muzzle devices found on military AK-74 rifles giving the AK-140S an authentic look alongside its functional recoil reduction. Constructed from stainless steel and finished with a DLC coating the brake offers strong resistance against carbon buildup and the corrosive ammunition commonly used in AK-pattern rifles. This coating also protects against the heat and wear generated by sustained firing helping the brake maintain its finish and function over time. Made in the USA by Arsenal this brake reflects the company s commitment to producing authentic durable AK-platform components. For AK-47 owners looking for a genuine AK-74 style muzzle brake with reliable American manufacturing the Arsenal AK-140S delivers proven recoil control in a rugged stainless steel package.
