Hey guys I was wondering what kind of bolt I need to get
for my stock full bodied Osiris autococker. (2k+ or Evo size).
I was gonna get a Slik Bolt so


OR


Thanks guys.

I'm not the Osiris guy around here, but the 2k+ is what you should go with.

The Osiris has been out for a few years so it'll use the 2k+ bolts, not the Evo length bolts.

Full body = 2k bolt
P-block = "Evo" size
The p-block design uses a shorter bolt because the block actually extends into the body of the cocker.
you said you have a full body cocker so you need the 2k bolt, any 2k bolt will work for you.
if it says P-block design or short bolt then it is for the P-block.
The P-block is a better design because it allows the bolt air inlet hole to exactly line up with the hole in the body for maximum efficiency.
P.S. Polish guy, you know cockers, c'mon just because it is an Osiris doesn't mean it is still not 90% autococker
