Just replace the buffer tube with a milspec and bamn! I ordered saturday and arrived today ( monday) . pretty solid for $72. Only draw back is no rubber butt pad. Its solid. For me however i don't need one. 308 this heavy has manageable recoil.

Its adjustable butt, length, and Comb. Came up perfect for me. Now i am just waiting on my new Vortex Viper to mount up and i am rolling.
