The Zhukov-U handguard shaves off 1.5 inches from the original Zhukov AK handguard 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, so you don't have to give that up to get the benefits of the Zhukov anymore. The Zhukov-U shares the same type of sturdy aluminum chassis as the longer standard Zhukov for strength and heat mitigation sheathed 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. Made in USA hand guard counts as one US compliance part for 922(r). Features: 1-1/2 inches shorter than standard Zhukov hand guard Fits stamped and milled AK-47/AK-74 rifles with standard-length gas systems Optimized for short barrel rifles such as AK-102, AK-104, and AK-105 Full length aluminum chassis for strength and rigidity Heat shield relieved to accept standard AK cleaning rod Durable polymer outer handguard M-Lok slots for accessory attachment Extended length for modern shooting techniques Vented gas tube cover UltiMAK compatible
