BKF M4 MOD-0 A5C 4.5lb Two Stage Combat Control Lower Build Kit

Description

New for 2020 is our BKF m4 mod-0 buffer tube assembly’s that is part of our new premium series. The premium series will offer a vast number of bkf components that have been made with the ar builder in mind. Not only does the premium series offer extremely high quality products, but it also offers very competitive pricing. They are available in standard, intermediate or extra power configurations.  These are manufactured for heavy duty use in mind. This buffer tube assembly is the perfect starting place for any high quality build.

This is standard in all rifle length gas system premium 5.56mm weapon systems ranging from 18″ to 20″. Also in all pistol length 300 Blackout weapon systems ranging from 6″ to 16″ weapon systems. 

The BKF A5 9 position buffer tube assembly’s are intermediate in length. The buffer and the tube are both 3/4 of an inch longer than a standard carbine buffer tube assembly’s. It also uses a rifle length buffer spring instead of the standard carbine spring. The summary is that it helps control carrier speed, modulates felt recoil and most importantly opens up the entire operating range of the gun. This allows the gun to operate correctly under a much broader range of inputs and variables. This typically translates to greater overall reliability.
