Compact and innovative design
The Umarex RP5 is as eye-catching as it is innovative. You can buy it either as a pistol or in the ‘Carbine Kit’ configuration we have here. Both are advertised as putting out around 5.5 ft-lb, but, somewhat frustratingly, a screw prevents you from removing the stock and turning the carbine into a pistol.
Measuring just 752mm and weighing less than 2kg, the RP5 Carbine has a two-stage plastic trigger that isn’t adjustable, but which is pleasant enough to use out of the box.
The safety catch, which can be operated from either side, is located just above the comfortable pistol grip.
The stock is short, but grooves in the forend make it comfortable to use and easy to shoulder.
There are two 9-11mm dovetail rails either side of the magazine loading port to accept a scope or red dot sight – there are no open sights. Umarex also provides a 30mm Picatinny rail option as well as an integrated rail on the underside of the forend.
Two five-shot in-line magazines come as standard. To load, you drop pellets into a hole, pushing a plastic bar into the main housing and then insert the magazine from the top of the breech.
Cocking and cycling a pellet is achieved by sliding the forend backwards and forwards, giving the RP5 a pump action that is addictive and fun to use.
With less than 5 ft-lb on offer from the two 12g CO2 capsules on the day I tested it, I’d consider the RP5 to be a dedicated plinker, and it’s plenty accurate to send tins cans flying as quickly as you can pump the action.
However, I would invest in a silencer – the barrel has a ½ inch UNF thread – as the RP5 has quite a crack. In terms of shot count, I averaged 50-60 before the power dropped and I had to change the capsules.
To do so, you’ll need to unscrew a collar at the very front of the stock, then a second cap to access the capsules. Install the first CO2 bulb with the thin end pointed towards the muzzle and drop the second in round-end first.
Then simply screw the lower collar up first, and then the cap to pierce the capsules and release the CO2 into the pressurised cylinder.
