Crosman 1077 RepeatAir Semi-Automatic CO2-Powered .177-Caliber Pellet Air Gun

This is a pellet repeater and will fire off pellets as fast as you can pull the trigger. Its magazine holds 12 rounds and this is an excellent small varmint control tool. It fires groupings under an inch at 25 feet and under 3 inches at 100 feet. A terrific plinker, varminter, and target shooter. Sights are right on at 35 feet right out of the box. Rear sight is windage and elevation adjustable. Front sight is fiber optic.

First session went great. Shot about 150 rds and had only a couple of jams which were easily fixed by popping mag in and out. Second session was as though someone sabotaged it while it was in the closet. Trigger became nearly impossible to pull, the clip would hang up, the magazine would get stuck (had to use barrel release to free it), and half the pellets wouldn't punch out. Extremely frustrating. Began recalling all the negative reviews I read before buying.Called Crosman - they set me up for warranty repair. As i was about to pack it, I suddenly discovered the problem: operator error. There's a tiny slide/latch on the magazine to line up the clip. Had totally forgotten about it. I put in a new cylinder, loaded her up, set the guide latch, and every issue I mentioned was immediately solved. Worked great once again! I'm so embarrassed.As for all the bad reviews here for this gun, I can only wonder if I've avoided these problems by being very gentle and cautious when handling (well, except for the magazine latch). After all, it's priced well under $100 and made almost entirely of plastic - and it's a semi-automatic. Or maybe the gun's not old enough yet. We'll see. I have 5 mos left on the warranty. Guess I better shoot 1000 more rounds before then.In the meantime, I'm very pleased. Crosman 10.5 domes, Crosman 7.5 HPs and Gamo Hunter domes worked great, 1-to-1 1/2 inch groups at 30 ft and easily hitting 2- and 3-inch paddles at 50ft. Get a handful of clips - they're too cheap not to and multiplies the fun.

Over the last few years I have bought a number of these crossman air rifles. (Don't ask me why!!) While the concept of the product is good. The product quality and CO2 cartridge seal and small mesh filter are not reliable, or in my humble opinion not good value. So I decided to investigate some of the perceived qualty part issues with this rifle, given that the manufacturer continues to sell this product knowing it could break down within a year.The number one issue, is it continues to lose its CO2 gas due to a defective seal that the manufacturer continue to assemble in this rifle. Please see the parts in question in the pics above.Given this is my 5th crossman rifle I decided to disassemble the rifle I just purchased "again" as it would not seal, despite just receiving it to find out why it was releasing the gas before I return it. As you can see there are a number of components that are depicted in the pics. The main item seems to be the red CO2 powerlet gas cartridge seal that is supposed to seal the gas from escaping. This is the number one problem with all the crossman rifle products i have purchased thru Amazon.it does not seal allowing the gas to escape despite utilizing the cartridge lube oil before inserting. The oring seems to lose its sealing characteristics not allowing the cartridge to seal effectively. It seems to work for around 4 to 5 months then the gas tends to escape. This has happened to everyone of my rifle purchases despite my continued dialog with Amazon and the manufacturer. The seal seems to be made of the incorrect material allowing it to harden over time, therefore not allowing the cartridge to seal effectively and lose it memory!!As outlined earlier the rifle works effectively when it is not losing it's seal, but overall the product quality is poor for long time use. This will be my last purchase of this product.Sorry to go on, but buyer beware when purchasing this crossman product. At least Amazon does the right thing!!

It shoots fairly accurate loud compared to my break action, one I zeroed it into my scope it shoots within an inch, so all in all its worth it as a co2 rifle for plinking, the magazine in it is terrible it skips pellets but only like 1-3. In the photo that’s around 10-15 yards

The rifle works as advertised, accurate, and truly semi-automatic. My only disapointment is a heavy trigger pull.
