From the manufacturer


Identical in form, fit and function to our model RB5000, but with springs and damping optimized for use with light loads, including subsonic ammunition.  This model was designed to work with guns that for whatever reason do not have as much energy input into their recoil system.
RB5000L KynSHOT Marksman Recoil Buffer is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the US Armed Forces.  This buffer is designed to fit any AR-15 with a collapsible stock.  This buffer was designed for 5.56mm / .223 cal. rifles.
If your .223 carbine model bolt is not locking back after final round ejection, first check your gas system, then check your buffer spring.  If everything checks, replace your RB5000 buffer with the RB5000L KynSHOT Marksman Recoil Buffer to remove less energy from your recoil cycle.
