Steyr Bolt O Rings x 2
These are replacement probe/bolt seals/O rings for the LG110, LG100 etc. They are fitted into the end of the bolt, to create a seal between the bolt and the breech (barrel).
Handy for when you get air blowing out the breach when you fire your rifle. It is also a good idea to keep spares in your gun bag in case one fails in the field.
They are black Viton O rings similar to the Steyr green O rings. Item 53 on the exploded parts diagram, part number 6390050.
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.
