PRODUCT DESCRIPTION

Note that this orange version called HDR50 Gen2 (Home Defense Revolver) is structurally identical to the black version TR50 Gen2 (Tactical Revolver) and only differs in color, therefore it is compatible with all spare and tuning parts for TR50 Gen2.

The German manufacturer Umarex, specifically their T4E department (Training for Engagement) introduces the second generation of their best-selling rubber and pepper projectile revolver called the HDR50 Gen2. It's evident that the company has listened to customer feedback and made welcome changes, and in turn didn't alter anything that works flawlessly.

The most notable difference, compared to the original version (11J) is the increase in muzzle energy to 13J, making it one of the most powerful short RAM guns in .50 caliber.

The second major change is a new 12g CO2 cartridge quick activation valve. It's been redesigned to be easily loosened by hand without the need for an Allen wrench. Nevertheless, it still does its job perfectly - in case of a threat, just bump the valve slightly with your palm to pierce the cartridge's nozzle and the gun is ready to fire. That way, you can carry the revolver indefinitely without the risk of the sealing rings degrading. When activated, an indicator pops up above the grip, signaling that the revolver is under pressure.

Other minor changes include an anti-slip grip texture, fixed sights with light-guiding fibers for easier aiming even in low-light conditions, a top Picatinny rail extended by 1 segment, and a recessed zone around the magazine safety pin.

The lower Picatinny rail for installing a laser or flashlight and the convenient trigger-integrated safety have remained intact.

You can use all kinds of RAM balls as ammunition, such as rubber, pepper or marking rounds. Also, due to the rotary magazine, the revolver is even compatible with non-spherical projectiles.

New - Carbine Conversion Kit

Maintenance

Since the gun is powered by CO2 cartridges, the sealing rings can become brittle and crack when exposed to the freezing carbon dioxide over time. This can be prevented by occasional application of silicone oil 1) by a spray bottle, where you simply coat the internal mechanism, 2) by applying a few drops of silicone oil to the nozzle of the inserted cartridge 3) by using an oil cartridge (easiest). It’s also not recommended to leave the activated cartridge in the gun for longer than necessary. If you know you won't be shooting for a while, release the pressure by loosening the valve.

Somewhat disappointed with the performance (in summer) and the life of the gas cartridge.

  • Excellent gun for target practice and other uses.
  • I didn't get the black one, but I'll settle for it.
  • After using it I see two main problems. One, the gas charge is not enough for two magazines. Two, sometimes some balls were not shot and got stuck.
  • It may not be a valid weapon for self-defense given the problems outlined above.
