Get the soft recoil impulse and quick sight recovery you are looking for in your ultimate competition PCC AR-15. The KynSHOT
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” when installed in a standard AR-15 carbine buffer tube
1. 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 spacers
The damping level of this buffer is intended for lighter, competition type 9mm ammunition loadings for best performance and longest
service life.

Please Note:

“Kynshot recommend using an A5/AR10 buffer tube with this buffer for optimal short stroke configuration setup”

This may require a modified bolt to properly reset the trigger. This method is recommended when using an unmodified bolt.

    This buffer is worth every dollar. You will need a A5 buffer tube if you plan on running it on a PCC.

    Hydraulic buffer

    Here's the deal. I wanted to build the softest shooting 9mm PCC possible. If you use the KynSHot RB5020SS buffer, JRC 8.75" long buffer tube and Sprinco green buffer spring you will get the softest shooting PCC around. KynSHot makes the only viable hydraulic buffers and Botach sells them cheaper than anywhere else.
