This version of the Discovery does not include a pump, tank, yoke or fill adapter. To connect your Discovery to a scuba tank, you'll need a scuba tank adapter with hose and a female quick-disconnect with male threads. The tank must have a K valve.

To exhaust air or CO2 from the rifle, you need to purchase the degasser tool.


Get into precharged guns at an unheard-of price and also get the accuracy of an expensive European rifle!

Benjamin has bridged the gap and taken the pain out of PCP guns. Not only is this as low a price as you'll ever find on a PCP rifle, but it's so easy to pump up that a wispy teenager could do it!

The Discovery has raised the bar for PCP guns because it uses only 2000 psi of air. While the European companies race toward higher and higher air pressures, Benjamin is going the opposite direction and making it easier than ever to use a hand pump. If you want to use a scuba tank or carbon fiber tank, you can do that, too, and get the benefit of many more fills than you would from a gun that operates with 3000 psi. The Discovery gives you a choice! The air reservoir is 135cc. The air tank has a male Foster fitting.

The gun comes with a hardwood stock, Williams fiber optic front and rear sights, and a built-in air pressure gauge.

When you open your box, you'll see easy-to-follow and easy-to-understand instructions that'll lead you step-by-step. If you're an experienced PCP user, you'll soon see that the Discovery is the easiest PCP you've ever used. If you're new to PCPs, you'll become a pro in just a few short steps.

If you want to switch to CO2, that's easy to do, but you'll need a degasser tool to quickly exhaust all the air before filling with CO2. Attach the optional CO2 adapter, connect it to a standard paintball CO2 tank and fill 'er up! Now, commence to shootin'!

With high-pressure air, you'll get up to 25 powerful shots before you need to pump up again. On CO2, you'll get a lot more shots per fill.

Things I liked: I like the wood stock, it feels good and points easy, I found nothing shoddy about this rifle, it holds air perfect. The trigger is much better than I expected. it is plenty powerful, chronograph reading from Pyramyd Air of 10 shots was 926 to 834 FPS. Accurace seems very good. I am glad I bought it.

Things I would have changed: The rifle is very nice except for it is too noisy for in-town backyard shooting. would be nice to have as a bundle upgrade something like a TKO muzzle brake. Otherwise nothing.

What others should know: I installed a 4x16x40mm AO Centerpoint scope using the high leapers UTG rings, that gave me plenty of room to roll a .22 pellet into the breach trough. I also installed a TKO 6 1/2 inch muzzle brake, it is still a little loud but not near what it was. I put out the extra $10. for the 10 for 10 test, I think it was well worth it to receive a near perfect rifle. I really like this gun.

Things I liked: Why I never purchased a "Disco" after all my years of airgunning and collecting, hunting, target shooting etc....I don't know. I finally just got one a couple of weeks ago. For me it is in some ways the perfect air gun. Compact and light, can carry out in the field all day, beautifully accurate, easily powerful enough for any small game, looks great, and simple to pump with a hand pump.

Things I would have changed: Shouldve gotten one sooner. Just wish there was a multi-shot cartridge like the Marauder models.

What others should know: You'll love this gun. PCP's always annoyed me because of the constant need to recharge. Now it seems my springers are collecting a bit more dust.

Things I would have changed: Improve shot count

What others should know: I only got about accurate shots before pressure dropped and point of impact started chaging

  • jerry from USA asked:

    how many fills from a 20 oz c02 bottle?

    • monty from USA asked:

      Is the answer 7-10 good powered shots on a fill of CO2 correct??

      • 65BAJA from USA asked:

        Can you leave the paintball tank hooked up? Like if I'm at the range and don't want to disconnect the bottle to shoot all day.

        To fill your PCP gun:
        1. Pick a source of air shown at right
        2. If an adapter is needed, one will be shown
        3. Add both to your cart to get hooked up
