Blitzkrieg Mil-Spec Carbine Buffer Tube

The Blitzkrieg Carbine Buffer Tube is a Mil-Spec buffer tube/receiver extension for any AR-15 and LR-308 rifle that the user wishes to mount an adjustable stock onto. This tube is designed for adjustable stock setups, but will work with a stock-locking device if you wish to fix your stock in place in order to be state compliant. This buffer tube will NOT work with rifle-style stocks. If you would like to set up your rifle with a rifle stock, you may want to check out our Blitzkrieg Rifle Buffer Tube.

The Blitzkrieg Carbine Buffer Tube is perfect for those who want adjustability, yet also want the option of making their weapon fixed-stock compliant (with additional hardware), in order to comply with their state’s laws.
