Awesome gun. Very accurate and easy to shot. What I mean is, length of pull, weight, and overall ease of operation make this a very likeable gun to shoot. Bolt would be hard to close for a smaller child but adults will have no problem. If you're thinking about just do it.

Nothing

Pay the extra $10 for Pyramid staff to shoot and check function.

After trying to get a 4$ replacement O ring on filler cap,for free, I couldn’t

There is a good chance that the O ring on filler cap will not hold your co2. Mine was dry rotted. Pyramid Air gave me a manufacturer link that dont Receive email. And I want to continue buying from Pyramid.

Good value for what you get, pretty accurate.

The bolt can be hard to close and I don't like the safety.

I bought this for my kids and they can't close the bolt. The way the safety works a kid could easily pull the trigger trying to move it. I ended up giving the gun away.

I like using a CO2 rifle as a trainer for teenagers (as well as just having fun myself). The stock has a nice fit to it and the iron sights, though basic, do work. The trigger pull isnt bad with very little creep and a decent let off. What surprised me was the accuracy (after it was cleaned, see below). With a variety of pellets, it was not really fussy. But I did get the best groups with the AA diabolo field (8.4 grs) and the Winchester round nose (7.6gr.) and the Skenco new boy match dome (8.64 gr.) All three gave 3/8 inch groups at 10 meters). This was on a rest using a 4 X scope.

Change it to a single CO2 cartridge gun or sell an adapter that replaces the 2nd cartridge. As reported by others, the rifle was filthy with a really fouled barrel, bolt assembly and dirty seals. After two hours of cleaning and tightening all the screws, the gun started to cycle a lot better. While this is not a high dollar gun, the final inspections could be a lot better. Also a higher cheek piece would be helpful when using a scope.

Be prepared to spend time cleaning the rifle as noted above. Also the safety was really stiff until oiled and cycled several times. All in all, a good value for the money

Someone will probably tell me I'm making a big mistake but I just put a used cartridge in the front position of the co2 chamber and a fresh one towards the breach. Works great.

Great for poaching squirrels The squirrel population in my backyard has gone down a little bit Gun feels good in hand and works well for hunting squirrels at close range I would prefer the .22 caliber but the 177 worked pretty good for the squirrel that I killed Just open the window cock the gun and let her eat squirrel killing fun is at your hands

Make it a bit more powerful I wouldnt shoot squirrels at far range wouldnt kill A squirrel and I had had to shoot this Squirrel three times before the dumb thing died But nonetheless it did the job

This gun is extremely accurate with a scope and with iron sites but I would recommend a scope if youre going to do squirrel killing but I would recommend this gun to anyone all around good gun

Exceptionally accurate, simple, very comfortable stock, light, either one or two cartridges may be loaded. It's nice to being able to load one full cartridge and one empty one if I only want to shoot 25 or 30 shots. At ten yards, it stacked 5 shots, center of a 1/4" bulls eye, one on top of the other for a 5 shot group of .20 inches. The trigger has a nice feel and is light. It loves H&N 8.4g Field Target Trophy in 4.5mm. I have not had a single flyer in the first tin of 500.

There is no gas discharge port, The only way to deplete the CO2 to take the pressure off the CO2 cap so the cap can be unscrewed to change the 12g cylinders is to dry fire until all the gas is gone. Having a discharge valve would be a great improvement. The open sights are 1950's crude, stamped steel and there is no windage adjustment and elevation adjustment is accomplished with a notched ramp, which is also only minimally precise. Thats fine for shooting cans, but inadequate for precise target shooting. Actually though, the accuracy is so good that not installing a good scope on it does it an injustice anyway. I installed an Optima 3-9x40 AO I had laying around and that seems to be perfect for it.

The CO2 cap had grit in the threads and was difficult to screw down or unscrew. Cleaning and lightly oiling the threads on the cap and gas tube solved the problem The bolt was dry and needed a drop of oil.

It is a great target and plinking rifle and wonderful not having to pump it up. At about 6 ft lbs of energy, it is only about half of the commonly accepted standard of 12 ft lbs required for hunting small small game. I would not consider it by any stretch, sufficient for hunting anything bigger than a frog.
I'll probably buy another just because I like it so much. lol

This is the gun to buy period! I absolutely love it, so much that I modified the internals, slapped on a nice scope, bipod and a DonnyFL to make it library quiet. This thing shoots dime sized groups from 21 yards plus, I am now shooting 13.43gr pellets at 630fps and 5.5gr pellets at 800fps and get about 50 usable/consistent shots at least. This gun is amazing that is all I can say, I wish they made a version that would take an 88g tank!

Make an 88g tank version, other than that this thing is perfect!

I made the mistake of buying an Umarex Fusion 2 and that was trash so I bought this instead and modified it, much better gun! Also this gun loves pellets in the 7gr range like the RWS Match 10 and Air Arms Diabolo Express.

Very accurate have a 4x16 scope 0n mine may be overkill but it's fun to watch the pellets hit the target. like that it has rails on the front end easy to put on a bipod. .177 cal shoots really good groups with crosman hollow points. lots of fun for the money.

wish it was not so hard to cock.

you have to let co2 to run out all the way before you can change it out.
