what material is the striker oring made from? Im gonna get a huge bag off McMaster because i find they seal better due to their extreme softness.

doesnt matter, i use tank orings on the striker sometimes

but the striker one is a bit softer.

i guess it would be rubber

yea but there are many differant types of rubber nvr mind found it on mcmaster. Silicone has good low and high temperature resistance. Temperature range is -65° to +450° F. Durometer hardness is A70. Meets FDA 21CFR.177. Color is red-orange.I would get the fep encapsulated ones if they didnt cost a million dollars. What AS568A Dash Number do I need for a slim striker spyder?

I had a problem with decocking on my LP spyder a few years ago - I finally called Kingman and they told me that the oring on the striker was a different size than normal/ They sent me a few extras and I never had that problem again. Might want to consider that before you buy a lot of them...

Just looked at them striker orings are about an oring width wider.

Strange, I've used urethane 9/16 x 11/16 x 1/16 (-015) on all of my markers strikers and have never had a decocking problem.

See, a lot of my friends said the same thing when that happened. Oh, well. Chalk it up to low tolerances!

I just emailed kingman lets see what they have to say.

I'm sure they'll say that you have to use their o-rings only. IIRC there's something in the VS manual about o-rings saying not to use anything other than Kingman o-rings.

kingman says 015-80D silicone on the striker and buna-n on the bolt. Im gonna use all silicone just cause i like their sealing ability better
