Get the soft recoil impulse and quick sight recovery you’re looking for in your ultimate competition PCC AR15. The RB5020SS buffer provides longer length and more weight for those who desire a short stroke competition action. With a length of 5.3”, this buffer will shorten the stroke of the bolt by 1.3” compared to our standard 9mm buffer when installed in a standard AR15 carbine buffer tube1. When installed in an AR10/A5 carbine buffer tube this buffer will shorten the stroke of the bolt by .5”, which can be increased by the addition of spacers2. The damping level of this buffer is intended for lighter, competition type 9mm ammunition loadings for best performance and longest service life.
