JP Enterprises SCS System Buffer Retainer Pin & Spring Kit, 1 x Pin, 1 x Spring, Black/Silver, JPSCS-BRP

Your SCS will never drop unexpectedly out of your lower again. With our JPSCS-BRP the spaces between the masses can now ride over the ramp that has been created if the user does not want their SCS sliding out of their buffer tube when taking their rifle apart for servicing.
