In this video we replace the Sheridan bolt orings on a Pgp pump paintball gun.
As I mention in the video, this PGP has a quick strip notch cut which makes bolt removal infinitely easier. Find the video on how to cut the PGP Quick strip notch here:

Besides the PGP, these Sheridan bolt orings will also be compatible on the PMI 1, KP2, PG, P-68 SC, Magnum, Long and Short Barrels and many other PMI and Sheridan .68 caliber brass pumps.
You will really need to add some type or oil or lubrication to the oring before reinstalling the bolt, otherwise there will be too much friction and your stroke will not be smooth.
