[wll2506]

Guys, I need the sizes of the O rings for the regulator and rest of the parts that are inside the compression tube.I think most are 3/4od x 1/16wall X 5/8id ? I ripped up 7 O rings already .. I think I may change to 70 duro Urethane.

Well just bought some 70&90 duro urethane O rings and I bought some of the next size down too.

Man I hope this works, my compression tube just eats these O rings .

X2. Got to knock the sharp edges off or you'll just tear up the urethane rings also. A small.set of needle files or some 220 grit wrapped around a bamboo skewer work well.

Yes I did but maybe I got to be more aggressive with it :-)

Another place with a big burr is in the muzzle end when you slide the pieces over the threaded area into the tube. The junction of after the threaded area and the smooth tube has been cutting the O rings also.
