This is the Umarex HDR (Home Defence Revolver). It has gained popularity in recent years for the wrong reasons. Its legality in England skirts the law.
Take note, HDR stands for Home Defence Revolver. This was never made to be a paintball marker!!!
Paintball markers haven't got the always-ready CO2 cartridge piercing system. Normal guns pierce the CO2 cart as soon as it's loaded, and the weapon is then ready to go. The purpose of the piercing system on this gun is to enable long-term storage in an always-ready state.
ON A SIDE NOTE: This reminds me of Russian liquid fuelled ICBM / SLBM missiles where the rocket fuel is kept sealed until needed as this gives them very long storage life and requires no maintenance :)
This gun is a .50 calibre.
I've measured the muzzle velocity for this 7.5 Joules version to be ~380 ft/s.
I've loaded them with non lethal rubber balls. The magazine takes 6 rounds.
The gun has 2 Picatinny rails for mounting accessories.
The 7.5 Joules version converts to 5.5 ft/lbs.
The more powerful 11 Joules version converts to 8.1 ft/lbs.
The legal limit for Air Pistols in England is 6 ft/lbs. It is higher for paintball markers at ~9.9 ft/lbs.
There are some website selling the 11 Joules version as a paintball marker. Note that you cannot legally use hard ammo such as rubber balls with these. They are only meant for frangible rounds like paintballs or chalk.
There are kits available online that can convert either version to 16 Joules or more, some boasting 20 J - 30 J. These are of course illegal.
Lastly, I am surprised that these guns are delivered by regular post with no ID Check etc. They could easily fall into the hands of young kids.
