Midwest Industries AK Alpha Series Krink Railed Top Cover Features The Midwest Industries AK Alpha Series Krink Railed Top Cover solves one of the AK platform s longest standing shortcomings by delivering a genuinely accurate return to zero. Two aluminum struts create an extremely rigid lockup when the cover is closed holding the Picatinny rail steady enough that an optic mounted on top maintains zero even after repeated removal and reinstallation. That rigid lockup also seals the action more tightly keeping dust and dirt from entering the firearm during hard use in the field. A dedicated recoil spring button engineered specifically for this top cover ensures smooth reliable function with every cycle. Construction and compatibility are built around long-term durability and reversibility. The top cover and main stability struts are machined from hard coat anodized 6061 aluminum while the steel locking block is made from 4140 steel giving the part the strength to handle sustained use. No permanent modifications are needed for installation so shooters can return the handguard or firearm to its stock configuration at any time. This top cover is designed only for use with MI AK Alpha Series Krink handguards and is not compatible with other generations or manufacturers products. Made in the USA and backed by a lifetime warranty the Midwest Industries AK Alpha Series Krink Railed Top Cover is available for sale at GrabAGun.
