BSA transfer port O Rings x2
These are replacement transfer port O rings for the BSA R-10, Ultra, Ultra SE, Scorpion, Scorpion SE, Ultramax, Hornet, Goldstar SE etc. Handy for when you are getting a puff of air from the side of the breech block when firing your rifle. It is good practice to replace the O rings when servicing/tuning your rifle.
Use a product like Abbey SM50 on the probe O rings to prolong their life.
They are black nitrile (rubber) O rings similar to the standard BSA version.
This is for 2 x O rings.
The picture is a generic picture of some O rings, not the actual O rings you are buying.
