Have a sharps done by Charles Haun the o ring I ordered from MC masters the part number is 2418t123 n the package it's only got 017 and 09125784 and a couple other numbers are they the right ones I can use them but the lever block is hard to open and close . it will shot a whole carbine match and the gun is shooting the best I ever shot a carbine.But this O ring seems to big
Thanks Allen
Allen,
I have been shooting a Sharps, with a Hahn conversion, and you do have the correct McMaster-Carr part number 2418T123 pkg. of 70. And yes the block is tight, I also use Pam cooking spray on the block.
Hope this helps,
Kevin

ok thanks Kevin how about the sleeve I grease it good but have to spray break free and let it set about 10 mins to get it out after carbine match that normal. using grease Haun recommens. And how many shoots will the o ring last I went threw 2 carbine matches it looks new

Immediately after shooting for the day I remove the block and remove the breech ring, upon doing this I have never had a problem with it getting stuck.
As for the o-ring @18cents each, I never re-use one. It is the cheapest part of shooting.

Thanks for the help Kevin.
Hi David,
If you need help just call, 410-627-4726.
The 017 on the o-rings is just a dash number McMaster uses.
