My new 250 is very good! NO action rust! I already disassembled it, NO internal damage!Phew..
Gonna revise the internals, already ordered the breech seal, piston damper and spring.
About the damper seal, you still have a few Garvin?
I noticed theres a rubber behind the oildemper, in the endcap. This rubber should prevent the demper for hitting the endcap steel.
Did you replace this part? If so, with what?
Did you replace the steel pistonrings?
