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

Good rifle for size and CO2.I am shooting wad cutters and it is accurate.I put a red dot on the rifle and it seems to hold very well.Remember, this is a single CO2 cartridge. I can get approximately 30 accurate shots from a single cartridge. For me that's great. I do not like to store my CO2 guns with cartridges in them.However if you want to shoot more than forty total shots you need to change cartridges.Nice adjustable cheek rest and good construction.

Used 3 co2s and now the thing constantly leaks...pos! Even tried pellgun oil on the CO2 tips and nothing...wasted 125$

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!!

The CO2 cartridge seal in the chamber will give out after a while and start releasing the air as soon as you put the new one in. I have just bought my third rifle due to this failure mode. Out of warranty so couldn't afford to send back for repairs.

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.

This is an edit my 1st review:You can still see what I said about the 1st review below.The replacement is good and cheap on gas too! I ran 7(seven) magazines thru it with one co2 cartridge 84 rounds and it still had a little gas left. I'm really happy I got a replacement instead of a refund. It's exactly what I expected it to be like. 1st one just slipped thru the QC crack.Because the magazine does NOT rotate! I'm returning it and asking for a replacement. Hopefully the replacement won't be defective also. QC at Crosman/Daisy, if they have QC, needs to be aware of this issue. I tried different weights and styles of pellets, didn't help it.PS: I'm not one to write a bad review because I didn't read the directions and damaged some item. I know guns and have several pellet/bb rifles and pistols

I'll start with I've taken rabbit and squirrels with this little bugger. It's fairly accurate. However like others have stated that the co2 leaks. If you leave the cartridge sit for few days in this at most you'll get a couple shots before its depleted. If you plan on using this pellet gun make sure you have a fresh cartridge in it.
