20 oz pure energy
Costs like $5 more than a stock cup seal, but totally worth the extra $
Well with my first gun, a Rebel 02, air leaked from the barrel right out of the box, so I replaced the stock cup seal with this one, and from then on, no leak. When I got my new Imagine a few months ago the first thing I did was replace the Kingman seal with this one. My warranty was still 1 1/2 years away from expireing, so I decided to test its limits. I shot a full 9 oz tank through my gun full auto without stopping until the sear didnt catch anymore, and still, no leak. This thing is AMAZING.
BUY IT!!!! Trust me it's a great investment, you'll never have to replace your cup seal again.
