Gun Type

The Crossman has introduced us with its’another powerful creation for the gun enthusiasts-Benjamin Discovery. It is a pre-charged pneumatic PCP CO2 air rifle. It is a dual fuel feature air rifle. It can use either CO2 cartridges or can be charged up to 2000 psi with a scuba tank or hand pump. As we know PCP air rifle is best for accuracy and consistency and CO2 air rifle is well-known for its power and precision, so for that in Benjamin Discovery, we get all the combinations of best features.

This gun mostly works with .22 caliber though .177 caliber version is also available in the market.

Outlook and finishing of the air gun:

The appearance of the Benjamin Discovery is ordinary and not that much attractive also. Sometimes the stock of this air rifle is compared to the oar because of its shape and that makes the outlook more authentic. The barrel of the air rifle is smooth, black in color and also thin one. It can be compared to a soda straw. Again the forend is short and the comb of the air rifle is low.

The completion is satisfactory with a blend of dark powder covering and dye on metal parts. The stock material is hardwood whereas the barrel material is steel and these are varnished hardwood. The finishing of the air rifle is not so fine quality rather it is of below average compared to the price level. So if you are seeking for a delightful mirror finish to the metal you should not waste your time to this rifle.


This rifle has come with mostly .22 caliber but .177 caliber is also found in many shops. But Benjamin Discovery is popular with .22 caliber pellet. The .22 caliber can provide more accurate direction than of .177 pellet and also can keep its direction accurate in windy weather too. This feature mainly makes the pellet popular among professional shooters to hunting lovers.


Benjamin Discovery is an amazing powerful rifle that can achieve any assignment from shooting focuses to chasing game. This air rifle uses a large tank of pressurized air for shooting pellets and thus make it a standout amongst the best airguns as far as power. If this dual fuel PCP air rifle is charged fully it can send a .22 pellet up to 900 feet per second and .177 pellet up to 1000 feet per second. Again approximately 26 FPE at the barrel it works out.  This incredible velocity and power make the air rifle an unbeatable choice for the new shooters to the professional shooters.

High Accuracy:

The accuracy level of this rifle is quite impressive for the shooters. By using .177 or .22 pellets from longer distances you can get a deadly accurate result. By adjusting the sights or the well-balanced 3.75-pound trigger pull can give more accuracy.  This accurate accuracy is one of the best characteristics of this rifle and it never neglects its users to convey.


The Benjamin Discovery gives 80% consistency in muzzle velocity. An amazing outcome of 1.2% can be counted with the extreme speed of just 11.19 FPS. The standard pressure of this rifle is 2000 PSI which is definitely an excellent consistency. Again the trigger pull weight also shows great consistency.

This air rifle has a 2000 PSI level along with a high-pressure hand pump (not included on the purchase list) can be used to fill the rifle with compressed air. When it is loaded fully, you can constantly shoot until there is a need of refilling it. Though the power plant of this air rifle is PCP it can be converted into CO2 operation with an inexpensive dual fuel fill adapter (not included in the package). This process is easy to fill from a paintball tank and this offers more shots from a single fill.CO2 operation is really great to use for both indoor use and outdoor plinking.
