Tuning HDR.50 tuning guide (power + no more jams)
- Thread starter Savagefox
- Start date
Thanks this is an awesome guide to boost power for Umarex HDR50/TR50. One thing I would like to note is that most TR50 sold in USA is missing the flow regulator disk inside CO2 cartridge chamber. So one idea might be to remove the valve block (as per your instruction) and since valve block is cylinder of same diameter as the regulator disk, simply cut the valve block to appropriate length, drill a tiny hole and use it as regulator disk. On second thought, forget about making the regulator disk since it's not needed anyway to leap into HPA "multiverse". I also noticed your barrel extension. HDR50 being 50 caliber (actually slightly less than 0.5"), a schedule 40 3/8 inch steel pipe has perfect inner diameter for barrel extension (0.493"), and pressure rating. Just design a jig which clamps on the bottom rail and also screw in to slots at top and there is the perfect inexpensive barrel extension for HDR50.

I purchased a HDR50 from a guy on Amazon that was pre-upgraded to 16J. Only about 20 shots per CO2, but that's some power.

Yes 16Joule upgrade is nice, but to get real power ("beyond multiverse") + many more shots per fill, HPA upgrade is necessary. I've seen youtube of video of people using 1100 psi and 1200 psi with their HDR50. Probably you can go higher than that, but certainly not PCP level (3000 psi) as internals were not designed for it.

Actually have to correct - is the TR50 revolver I have.
I don't think I'd ever bother with HPA as it's more of a fun thing for me and firing rounds balls isn't particularly accurate anyway.
