Hey all, I have recently purchased a used 
in .30 and getting to know it in my backyard shooting area. I'm limited to 37 yd max range, unfortunately. Last week I noticed the bottle pressure had dropped 30 Bar overnight and discovered I could hear a leak at the weep hole! Another thing that got my attention was a fairly significant variation in FPS between consecutive shots that is not what I would consider normal for this rifle. 900 - 860 - 880 for example.
Ordered a Huma reg rebuild kit, PN 12-6, along with the rifle O-ring kit and got busy watching those excellent BRK maintenance videos. Rebuilt the regulator last night and was pleased to see it held air again! Did not find any obvious bad O-rings so I replaced them all after cleaning everything up. Set it to 150 Bar and shot several magazines through it. Variance is down to single digits and my groups are more consistent. This thing loves Hades! Currently set at PW9, 890 FPS, 79FPE. 6 Mags from 250-150 Bar. Had some fun with the Shoot-n-See while I was at it. Prone w/bipod. That is good shooting for my shaky a$$! I have got to find a place for longer distance shooting.
