Hey guys i'm having trouble finding the Thread size for Impulse threaded barrels.  Just wondering if anyone has any ideas for me.  I think they are 15/16-12UN Dual Lead.  Can anyone confirm that?

Yes, that is correct. But I'm pretty sure it written...

Great thanks, this site is awsome, i own 2 impulses ( well only one is functioning) and i needed to confirm the thread.  I have a machine shop and am machining a custom barrel to include freak inserts.

Maybe you could help me with another problem.  My other impulse is leaking around the noid gasket and no matter what i try i can't seam to get it to seal, lube/no lube, tight/not tight, it's driving me crazy.  Any suggestions?  Where can i pick up another gasket or is there an easier fix?

Glad you like the site! If you don't end up finding a gasket lmk. I can probably help you out. Also, try replacing the orings on the ram assembly, sometimes if those are worn it can seem as though the noid is leaking...when it's really not the problem.

So what is your custom barrel going to look like? I'd love to see pics when your done!
