Question: How long does it take to fill this gun up to 2000 psi?
Document: It takes about 70 pumps to get it to 2000 psi from empty, but I pump it up once the pressure falls to 1000 psi, and it only takes about 50 pumps (about five minutes or so...I go slow).So far, I haven't really found anything bad to point out about this gun other than it is a little loud, but that won't be a problem if you have a big yard and no neighbors close by.
The rifle arrived with a broken/missing safety. The main screw attaching the receiver to the stock showed it had been removed and replaced with the incorrect size screwdriver. After charging the gun to the recommended pressure of 2000 psi it dropped to 1000 psi after two shots. The accuracy at 25 yards was less than impressive. The gun lost all pressure over night. To be fair I think I received a defective gun which was shipped inadvertently. :(
Filled with CO2 using a paintball cylinder and the 'Benjamin CO2 Fill Adapter', it shoots many pellets and stays in the low end of the operating pressure range a long time because the liquid CO2 boils replenishing the CO2 gas in the storage cylinder on the gun. The velocity isn't as high with CO2, but you can shoot and shoot and shoot. The gun is a nice looking piece of work. I can't really tell if the stock is wood or plastic.
Time to pump this bad boy up. I must admit I was a little bit concerned. No need to worry I pumped this unit up to 2000psi with NO problem. It was really easy. The trick is to make yourself pump slow and deliberate and take full strokes. I wish I counted but Benjamin literature indicated about 110 pumps should fill a empty gun. Even though my air gage showd 0 air pressure I think it had a small amount of air in. It.
This is the best value on the market for a PCP single shot air rifle in terms of cost and performance. I opted for the 22 version that includes the hand pump but decided it's easier and more enjoyable to use a scuba tank pony bottle (19 cu ft) as my air fill source. The rifle's fill level is 2000 PSI, which is 1000 PSI less than European PCP rifle versions. Since the pony bottle fill level is 3000 PSI, this gives me many (30-40 fills) from it.
Awsome gun, love shooting it as an alternate to shooting up expensive ammo. Get an extra barrel band for accuracy and a TKO to quiet it. will shoot quarter sized 15 shot groups @ 25 yards and have made kill shots on birds as far as 75yds. Only thing i like about it over my marauder 25 cal is it takes a lot less pumps  to fill it up for a lot more shots.
I am very impressed with the accuracy of this rifle however the finish (bluing and stock) is not what I expected from a $259 air gun. I wish Crosman would offer the Discovery with all of the improvements/mods that many people are doing (adjustable trigger, second barrel band, angled bulk fill fitting, upgraded stock, hammer de-bump, power adjuster/degasser, power valve/piston).
Only gets hard when you get real close to 2k PSI. Figure it will take about 30 minute to go from 0-2k. Once you've filled it once, don't let it drop below 1k for sure, I usually refill at ~1200. Only takes 5-10 minutes that way.- Trigger is fine for a gun in the price range.CONS:- The only con I can think of, that is not something that is already advertised with the gun, is that it is LOUD.
I would not recommend this gun for anyone under 16-18 years old. It is NOT a toy, and the pump does take some effort when you get near the higher PSI ranges. Someone smaller may have trouble and bad form while pumping could injure them, or break the pump. You don't want to play around with air tubes and hoses pushing these kinds of pressures. Even if you have a scuba set-up, I would not want a child operating it.
Seems to be made well,  you've all seen the reviews of how loud it is and that you need a muzzle break and believe me you do. It's louder than my 22 rimfire carbine. My biggest disappointment so far has been that the point of impact changes as the air pressure changes. If you have 2000psi the point of impact will be severely different from having 1200 psi. Also you're only going to get about 20 shots at full power. If you're 20yds and in you might get 30.
