Crosman Benjamin Discovery Pre-Charged Pneumatic PCP Dual Fuel .22 Air Rifle and Pump

Pre Charged Pneumatic (PCP) Rifle with Gauge

In the past it was not easy to purchase a rifle that you could add pressure to on your own. The Benjamin Discovery is a .22 caliber that allows you to use a scuba pump or a Benjamin pump. You can fill up the rifle’s 2000 psi tank with this pump. What I like about this PCP rifle is the fact that it has an easy to read gauge at the bottom of the rifle. Another plus is that it can read both the CO2 and compressed air levels, which you will see clearly labelled. The green zones in between indicate that you are pumped and ready to go while the 2 red zones on either side indicate if the tank is full or empty.

Easy to Use Quick Fill Adapter & Pump (Optional)

In order to pump, the rifle has a quick fill adapter on the nozzle end of the rifle. This is where the pump is usually connected to do its magic. When pumping the rifle tank, it is advised that you pump slowly and it takes an average of 50 pumps if empty. Once you pump, you can get a velocity of up to 900 feet per second, which means you can shoot fast and far. With each full tank, you can get up to 25 shots before you have to refill. After filling the tank, release the valve sharply before disconnecting the pump.

Dual Fuel Capability

What is great about the Benjamin Discovery is that you can use 2 types of pump fuel. You can use CO2 (or carbon dioxide) or you can use regular compressed air. It is possible to purchase gas canisters of both types of fuel; it is up to the rifle owner to choose the one they prefer. It is important that you use one type of fuel at a time and avoid mixing, because mixing the two can be dangerous. You can use a valve to empty the fuel you are currently using and use a fresh canister to pump.

Multiple Safety Features

When I purchased the Benjamin Discovery, I had to ensure that it had the necessary safety features. One of them is, of course, the safety lock located near the rifle. One simple click and you are either hot or safe. Another safety feature is the bolt handle which is what allows you to load and use a crossbow mechanism to enhance safety. There is also the valve cap, a plastic black cap that protects the quick fill adapter. If there is one safety precaution you must adhere to, it is to ensure that dirt does not enter the nozzle. Therefore, I always make sure that I have the cap on after each refill.

Hardwood Stock & Fiber Barrel

One of the great features about the Benjamin Discovery is the rifle stock which is made of some kind of hardwood. The nice finish gives it a rugged look which is great for carrying out to the hunting grounds. The rifle grip is also quite long and offers comfortable usage for the hunter. The front and rear sight are both fiber optic. The butt is also well designed for a nice rounded out finish for your rifle stock. The design is ambidextrous which means that both left and right handed people can use the Discovery.
