pm8 bolt oring question

sparky1 · 07-06-2011, 01:22 AM

So, quick question about the internal o-rings on this marker.

there's 2x 017 Urethane o-rings that go inside of the top-hat and inside of the front firing can.

my question is this.

is it alright to use BN70 o-rings in there instead of urethane?

currently ive got BN70 o-rings because that's all ive got, but im unsure if it's even necessary to use the urethane o-rings since i believe the o-ring monkey kit comes with the BN o-rings.

I think the manual says they are urethane but I have used BN with no problems. They are softer so they should scratch you're bolt less but make sure they are well lubed with something slippery like hater sauce and you should be golden.
