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.

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

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.

One of the best pellet guns I've owned. This is my third one. Had 2 others when I was a kid and wore them both out. Crosman has made very few changes to this 20+ year old design because it's pretty much perfect. The only thing that's still a little difficult is setting the CO2 cartridge. It's just in an awkward spot and you have to turn it fast and hard to make sure it punctures and you don't lose pressure. Other than that it's a great gun. Also, my first 2 shot around 630 fps, but Crosman upped the speed to 780. I used to get about 5 or 6 mags before changing co2. Now I only get 3. Some of the reviews say you get 4 mags, or 48 shots, but at that point you start getting noticeably weak shots and you're just wasting pellets at that point, so I've been changing co2 every 36 shots. Also, a small drop of the Pellgun oil on the tip of every cartridge keeps all the parts running smoothly and every shot consistent. The front sight is a different as Crosman added a fiber optic to it. The rear sight is fully adjustable for windage and elevation. And no, it's not difficult to adjust if you know anything about zeroing open sights. The gun only comes with one mag and one clip. The clip inserts in the mag. Buy extras of both as I did if you don't wanna spent most of you time reloading. As far as accuracy goes, the barrel is rifled pretty tight for a pellet gun, so that makes it more accurate than most in my opinion. The trigger isn't on a pivot but more of a slide that activates the rotary mechanism and co2 impingement device. It's not heavy at all. I can make tight double tap groups on my back yard target at 15 yards. I think I'll probably put a red dot on the dovetail grooves since I'll be able to line up on a target faster (birds). All in all it's a great pellet gun. Never found one better for less than $100

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.

Love this rifle! It's got some real power!
