This is sick!
Ive had a lot of fun with this thing! It’s unfortunate that it doesn’t come with bbs and C02 cartridges but it’s not that much more to buy separate. I got these bbs for $3 https://www.amazon.com/dp/B007II3FQS?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 they uselly go on sale so keep your eye on it. The gun feel and quality is very good and has some weigh to it. Be safe out there.

8/10 I would recommend
I got this on sale for $30 USD and was great for its price! I’ve owned this for 6 months. Shot over 1500 bbs. VERY IMPORTANT: Must use oil on top of c02 before install ( I use pellgunoil ). This prevents the seal from becoming frozen and cracking or breaking causing c02 to leak. Only issue I’ve ran into is that the bb sometimes doesn’t fire. Otherwise it’s decently powerful, accurate, and most importantly very fun. Cons: - mostly plastic - very lightweight - stationary slide / non blow back - not full size magazine (not to be confused with mag capacity) - may sometimes not fire bb - Simply a Air gun not a great training pistol, not able to replicate a real firearm. -c02 installation may be difficult due to part of the air gun being in the way. Pros: -Size similar to firearm counterpart -3 dot sight is decent - Accurate - good mag capacity - c02 lasts a good amount of rounds - great for plinking - price is reasonable - able to attach light/laser Overall I’m very pleased with my purchase.

New BB magazines shoot more accurate that original factory bb clip.
Update: I bought a 2 pack of replacement clips for this BB gun and now the bb gun shoots straight like it should. Most people get a good bb magazine with their purchase, but I was unlucky. The original clip still shoots bbs in all different directions, but there is nothing wrong with the bb gun. I have tried several different clips with this gun and 1 clip shoots really really accurate, 2 shoot reasonablly accurate, and the one that came with it shoots all over the place. I have changed my review from 1 star to 4 stars because I can now get it to shoot straight with the replacement clips. I am still taking off 1 star because each clip shoots different. My advice is to get extra clips and test each one for accuracy. If they shoot straight and feed correctly, keep them, but if they don't, return the ones that are not satisfactory. If you get a BB gun that doesn't shoot straight like I did, just order a 2 pack of the extra bb magazines for this gun. Note: these extra bb magazines are recommended by Amazon for this gun and they also work great in my Crosman C11 bb gun. As for the people who complain about it being hard to screw in the CO2 and the gas leaking because of the way the handle opens, try taking the handle off carefully by gently pulling one side up and it pops off and goes back on. See attached pictures and video. Original review: This has to be the most inaccurate bb gun I have ever shot. The BBs don't shoot straight out of the barrel, instead they hit up, down, right and left, basically everywhere but where I am aiming. When shooting at a circle from 12 feet away, they are hitting all around the edges of the circle, but never in the center. With my other BB guns, even if the sights are off, the BBs hit in the same place and I am able to adjust my aim and shoot the center out of the target. It does, however, shoot with great power (over 410 fps) and is easy to work and the trigger pull is nice. It even looks pretty and like a real gun. This thing is kinda worthless as a BB gun for shooting things because it will not shoot the BBs out straight. The BBs curve in all different directions, so there is no way to adjust my aim. One shot will be high, the next low, the next up and to the right and then the next one curves to the left. By far this is the most inaccurate BB gun I have ever seen, but it sure does look nice and realistic. I love the fiber optic sights, too.

Lots of fun
Simple and so far good. This does look real so treat it that way! Not for unsupervised kids! I give five stars because of price and function. This is basically a dangerous toy. It’s probably strong enough to cause serious injury or death to small animals. I would not recommend trying to use it for that however because it’s not really high enough power to assure efficacy for hunting purposes. It’s lots of fun for backyard plinking at targets and cans. It’s fairly accurate for a smooth bore BB gun. Holds 19 shots max and the only malfunction we had was when we tried fitting to many in the magazine, I have two adult sons that played with it for hours (800) rounds so far and 4 cO2 cartridges. BB’s ricochet so think about safety glasses and a softer backstop. “You’ll shoot your eye out!”

Poor range -- AWFUL DESIGN!
The range of the "gun" is extremely limited by awful design. That is, the gun expels the BB only a very short distance. If your intention is to startle deer, raccoons or other animals away from your house, it is nearly useless. It emits a kind of snapping sound, but that's about it.. The BB itself travels only a short distance before falling into the ground. In other CO2 guns I've had, the cartridge is inserted into a chamber that allows a nearly complete seal by rotating a knurled bolt into the cartridge chamber. This allows partial (almost complete) sealing of the cartridge chamber before final rotation of the knob to puncture the cartridge. In this "gun" the cartridge is inserted into the base by sliding the handgrip backward and dropping the cartridge into position. There is no actual chamber for the cartridge, only some plastic guides. The handgrip blocks access to the puncture screw, which makes it difficult to turn the puncture screw. In turn, that allows most of the gas to escape before the screw can be reasonably tightened. The initial loss of CO2 gas is what causes the woeful range.. Really, REALLY BAD DESIGN I

Reliable For Fun & Target Practice
Its Powerful enough for use of security and target practice. Definitely not a TOY!!! Make sure this isn't left out for children to get ahold of, seriously dangerous if used the wrong way.
