acs bolt o-ring?

[h3ctor]

o great, why is it so hard to get this damn marker working!!!

ok here it is, new acs bolt, dry fired lots of times and also with paint.
in the end I had a crapload of paint inside and a huge huge mess that im still cleaning up.

no problem....until i find that the oring in the acs bolt..u know near that screw,..well its like mangled. wtf!!

what will this cause it to do and the hell do i get one of these orings..
