So, I took apart the Bulldog M357/Star Wars blaster and put on the Pitbull barrel supports and went on to put the Hill depinger in the tank and the Oring was too big and sloppy. No way it was going to go on without beating it in with a rubber mallet, so I put on a smaller Oring with some silicone oil, and it went in firmly. Now I was worried, so I called Airgun Revisions because they repair them and asked about it. He said the small Hill depinger would greatly lower my power because it is making a small plenum so I ordered one of Revisions that is much larger and will not affect my power. He also said the barrel is so thick that it doesn't need barrel supports and they won't do anything except make more back pressure in the shroud that could cause the shroud to blow up on the M357 and that the DFL Ronin that Utah had recommended and I bought would be okay on the original Bulldog but was much too small for the M357 causing too much back pressure and not being affective so I should have gotten an Emperor. So, I guess I wasted around $250 on the barrel supports, Hill depinger and Ronin. When I was putting it back together the spring for the safety shot across the room and it took about 10 minutes to find it, but I did get it back together so I can start over again when the new and improved depinger gets here. 
What a day. I almost got a TexanSS but they are 10 pounds without a scope so that was not happening.
