Here's some info on the Metrics plug.......

To get you started.....

First determine whether your gun has the 5/8" O.D. plug or the 7/8" O.D. plug. Huntsmans built from 2001 up to and including 2004 used the 7/8" plugs. Huntsmans and Sidekicks manufactured in 2005 and up until the time they discontinued used the 5/8" plug. You should also receive some "o" rings. These are to placed in the primer pocket of the new plug immediately under the primer to seal it, avoiding most if not all blow back. You will no longer need the red primer carriers with the new stainless steel model.

Attn: Nick

They are a great bunch of people at this place. Nick and Busta worked collaboratively and were instrumental in the creation of these plugs. Last I knew the plugs were priced under $29.00 (when I purchased mine) and that included the shipping.

Have fun!
