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

   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.

   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
   

4. Demo of This Cool RepeatAir 1077 Verified Buyer – 17 April 2025

   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 ngclab.com.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 ngclab.com 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 ngclab.com does the right thing!!
