.50 Hammer leak is found.What do you bet that I can't buy this part? I can't even find a parts list to even give the broken valve (?) a correct name :( Oh yeah, a dilly of a pickle to tear down the rifle to find the leak. I was expecting a blown o-ring that I could easily replace. Hate to send...

Looks like I am here all alone............nobody cares to learn something that may be your own issue some day? So I had this crazy idea that the brass seat for the regulator piston to seal against... surely must have an O-ring to seal it in the aluminum body....and it could be leaking full...

Well CRAP. I received the 3mm Delrin rod and made a new seal for the end of the regulator piston. Aired up and it now holds air from leaking out the barrel but has no power. I've had it apart a dozen times changing regulator stack and shortening the piston seal (that I made too long on...

I got both regulators from Bagnall & Kirkwood $$. Arrived in nine day :-) Second regulator came in at 90 Bar...perfect. First regulator started at 200 bar. Had to degas and reset several times to get it reduced to 150 Bar. All good here and GREAT again :-)

Well the plastic seal didn't work......at all. Apparently too hard to make the seal. Fire a shot and it bleeds the air out the barrel like it does when you hit the low reg pressure limit. Possibly may be too short, but I never measured the OAL of the original one before I dressed it flat...

**Remove the indent with 1000->2000 sandpaper ** I chucked up the second reg piston and used a wet stone to remove "most" of the dent as square as possible and then polished. Surgically cleaned. It made the 16.02 mm piston shorter to 15.98 mm. Results are the same....still blows thru it after...

<<Utah airguns sells the brass pistons>> I think I'll go with complete regulators so I don't have to deal with replacing those tiny ID bore 0rings again. Do you run your washer stacks dry or lubed. I have smeared a light coat of silicone grease on them, dry and just silicone spray on other...

1st reg was factory setting, second reg has never been set above 100 bar. Just took it apart again and both pistons are 16 mm (plastic). Bagnall and Kirkwood has the brass pistons..... or the complete regulators. Huma-Air has the M3 First Stage Tuning Regulator that adds 23 mm to the bottle...

Gun was working fine and then, after sitting for a few weeks, full bottle pressure was reading at the 1st and 2nd stage gauges. Swapped gauges. No change. Rebuilt the second stage reg (all 0rings). No change Rebuilt the 1st reg (all 0rings) No change. For history, have only adjusted the 2nd...

I think I have it figured out ( long story). Took it apart again and stoned the regulator piston seal. I could not get the indent completely removed. Put it back together and it improved a tiny bit. Got a new regulator piston from PA and IT DID NOT have the seal on the end of the piston. Cut a...

Really not that hard to replace the O-rings once you figure it out. Bleed it out by dry fire. Air cylinder spins out and also spins apart. Regulator body comes out with the 2 top and two bottom screws and the regulator body comes apart with the remaining two screws. I took it apart again and...

Takes 7 to 10 shots to get to full power. Sits for ten minutes and then 2 or 3 shots to get full power. Cleaned the regulator and replaced all the O-rings. I don't have the little cylindrical rubber seal in the end of the regulator piston. It IS indented with the seat it seals against...

As in my original post: "Barrel looked spotless right after the first patch...but I kept going till I gave up and replaced the breach O-ring, put the barrel back on and fired a shot out the back door" ......The next day, shot a few fouling shots and then shot the target. Accuracy returned...
