Mech Tech Glock Telestock
One of these is the starting point to design your customized Glock Carbine Conversion Unit (CCU). Each base model comes with a 6" Standard Rail and Molded Fore Grip. If you have your own M4 stock, buffer tube, castle nut and lock ring, this M4 Adapter will accept both commercial and Mil-Spec tubes. Every unit is test fired before it ships. All of these rails are Picatinny.
