The Heat-Treated Castle Nut screws onto the AR15/M4 lower receiver extension (buffer tube) and keeps the receiver extension and lower receiver end plate secured in place.  The large notches allow for positive engagement with a castle nut wrench for proper installation and torque.  The smaller notches provide a location for the end user to stake the castle nut to prevent accidental loosening.

Finished in a Mil-spec manganese phosphate.

The Zhukov-U Hand Guard shaves off 1.5” from the original Zhukov AK Hand Guard to accommodate shorter barreled rifles and pistols, and keeps the front end of full length rifles a little more lively. The shorter version also allows us to accommodate the military issue cleaning rods.

The Zhukov-U shares the same style of sturdy aluminum chassis as the longer standard Zhukov, providing strength and heat mitigation in a comfortable, injection molded exterior for superior ergonomics.

The Zhukov-U includes M-LOK slots for accessory attachment, and is fully compatible with the UltiMAK gas tube rail. Installation requires removing handguard retainer.

The Magpul Enhanced Receiver Extension is a 10-position, Mil-Spec sized, SR25 / M110 profile buffer tube optimized to fit with the full line of Magpul Mil-Spec Carbine Stocks.

The Magpul M-LOK Bipod Mount allows for the attachment of most Harris®-style stud mounted bipods to M-LOK compatible hand guards and forends. The M-LOK Bipod Mount offers a low-profile, robust, and elegant mounting solution for the most common bipods on the market.  By utilizing the direct-connect properties of the M-LOK system, the bipod sits closer to the mounting surface than other adapters while providing superior support to the bipod for strength and stability.
