This version of the Discovery includes the gun and the Benjamin 3-stage hand pump with an attached hose that has a female Foster quick-disconnect fitting on the end. Connect the Foster fitting on the end of the hose to the air reservoir on the rifle.

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

Please Note: The gun is warrantied for 5 years, but the hand pump has a 90-day warranty.

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/hand pump combo, but it's so easy to pump up that a wispy teenager could do it!

If you prefer to use a scuba tank instead of the hand pump, you'll need a scuba tank adapter with hose and a female quick-disconnect with male threads. The last item already comes with this kit. The adapter fits tanks with a K valve. The air reservoir has a male Foster fitting.

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 gun comes with a hardwood stock (14" length of pull), Williams fiber optic front and rear sights, and a built-in air pressure gauge. Included in the package is a hand pump that's easy to use and very clear on showing you when you've reached maximum operating pressure.

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. A degasser tool lets you quickly and safely exhaust all the high-pressure air (or you can just shoot the air out). 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:

This is my first PCP rifle. I love the accuracy! I am a fan of trigger update mods so I immediately ordered the $49 upgrade from Alliance Hobby. With the brass trigger and adjustment screw it is now a smooth and easy release. The hand pump works well and seems to fill to 2000lbs with about 80 compressions. I think its an excellent rifle for the money.

Things I would have changed:

Nothing yet.

Things I liked:

It has a pressure guage. Its lite weight. It is accurate. It is not difficult to pump up. It shoots hard and straight. It has a wood stock.

Things I would have changed:

I would carve the stock a bit more. It is pretty blocky through the pistol grip and forearm. I would not put the dark stain on the stock which is almost like paint. Cant see the wood grain, I like wood grain. I will likely sand it down later. Its a good gun, can't really knock it too much. It is kinda loud but some of the reviews make it sound worse than it is. Its not an indoor gun but out in the country where it live doesn't seem too much at all.

What others should know:

This is my first PCP. Shot pellet guns for years and some pretty good quality ones too, BUT this one is a pleasure too shoot. It is fun and accurate, Basic gun, No frills. I shoot it (pressure) in the mid-green section of air guage and get 10-15 shots that are practically same whole. Highest green into high yellow doesnt do much good, those 5-6 shots do not group good. If you get down to low green into top of lower yellow and want to shoot another shot just hold an inch high, but its time to air up at that point. The sound changes and starts to squeek a little at low air, you will know it is time to pump up. If you have varmits as we do the gun really knocks them down. I have mostly shot Crossman Premier 14.3 gr. so far. I have mostly shot 25 to 40yards and it does it well. Loading is a little tight with a scope but you will get use to rolling the pellet into the bolt face. Wife likes it too. It is not a toy, requires adult supervision.

Things I liked:

For somebody that didn't really want to get into PCPs, it's a great intro rifle for the price. Lightweight and pretty balanced, love the enhanced sights, very accurate right out of the box shooting Premiers

Things I would have changed:

Again being my first PCP, some of these may just be part of owning a PCP. Biggest would be the charging via the hand pump. A longer charging line would be nice so you don't have to lay the rifle on the ground while pumping, less strokes for a charge or easier strokes. Possibly a larger breech for people with fat fingers and a better quality rear site. There is an elevation screw but mine didn't even touch the barrel until the screw almost fell out so I loosened the mounting screw and shimmed it. Not very professional but works for now.

What others should know:

I've owned plenty of gas charge, springers, CO2 and pumps but this is my First PCP. If It wasn't for the limited shots between charges, this would jump to the front of my favorites.
