The reg o'rings have been an issue on several people's guns, or at least from I read in this thread and several other. I had a leak on the fill o'ring. If you disassemble the tube there is a small countersunk screw with an o'ring on the fill end. If you have the o'ring pack that came with the gun there should be a couple in there.

It's important to get the seal kit from Joe first and then see if you can determine the general location.

Thanks everyone. It appears to be leaking out of the barrel, so I'm guessing it's a poppet issue. Before I tear it apart, I emailed DAR to see if they have orings available, as mine did not come with any, and I'd like to have some on hand in case I need them while it's apart.
With mine the poppet issue was cured by lapping the poppet against the valve face using a cordless drill at slow speed.
I told Joe at Dar to drill a hole through a steel plate use ultra fine sandpaper on the plate , and spin the poppet from the opposite side with a cordless drill , and he did that said it worked perfect , and Joe said he was going to do this to all the guns they were sending out that they had to replace the defective o rings on .... so the new guns they are releasing should be good to go now ...

Perhaps but I had issues with the poppet stem catching on the guide on this last one. I will be going back inside both the others to check for any binding.

The brass inset the stem goes through had sharp edges that would catch on the stem and give inconsistent velocity. Just deburred it and polished it up with some mothers mag polish.Same with the poppet. Mothers mag polish or even baking soda based toothpaste between the poppet and valve face with a drill works great.As far as the bleed screw.... a small piece of thick cross section oring beneath the ball bearing will seal it right up. You can even source small rubber bb's that would work well.Recently moved and put this one up for sale a while before moving and never got any takers. Just went down the basement and pulled it from the box. Pressure right on full where I left it. May have to find a scope to put back on it. Handles well!
Thanks Bill. It had a few things to be taken care of but it's a fine shooter. I slimmed the stock because it was just too chunky for my liking. Polished the barrel, Turned down the reg, made an ssg and she gets 50 shots on the reg with Crosmans at 900 fps. Glad it didn't sell now.A 177 set up at about 15 fpe would be a nice rig also.
