Direct replacement buttstock for AR-15/M16 carbines is designed to withstand the rigors of the modern battlefield. Slim stock features a sloping cheek weld for a firm fit and improved user comfort. The dual side latch release provides easy adjustments and is set up out of the way to remain snag free. Premium chrome-silicon locking spring ensures a positive long on the receiver extension tube and long service life for the stock. Internal anti-rattle feature provides a snug fit to minimize wobble on the receiver extension tube. Rolled toe and angular butt plate allows for easier shoulder transitions and better fit when using body armor. Non-slip rubber butt-pad helps keep the carbine on your shoulder and increases recoil absorption. Two sling mounts allow you to utilize different mounting options.
