When the gun was working it was incredible. I then started having issues with the seal on the C02 cartridges. When I tightened the base nut to compress the Crossman Co2tubes they would either leak out fast or if I didn’t shoot the gun it would lose all pressure within an hour or less. The fine machine thread is designed to wear out in no time. When it shot in auto mode it was impressive. Just lost reliability.

As soon as I opened the package and filled up the magazine and put in CO2 cartridge . I went to pull the trigger and the seal just if blew or some how manufacturer error either way NOT happy I haven’t even been able to shoot it yet . I wasted 3 additional CO2 cartridge thinking it was me doing something wrong . Ugh

Overall, this gun is truly a masterpiece. It functions perfectly every time and the only issues I’ve ever had was a bb got jammed in the magazine, however this was easily fixed by removing the mag spring. I love how this gun is easy to take apart and put back together. Very easy to use, operate, fix and customize. The only thing I would change about it is the magazine, I would prefer if the magazine had a notch to fit a speed loader in and a tab catch to keep the hole open instead of destroying my finger nail. I would also like it if I didn’t have to carry a huge Allan key around to put in a new co2 cartridge. Overall, amazing gun

I was expecting the auto repeat to be slow but am amazed at the speed it fires! This is a high quality pistol. I will likely get the rifle version of this.
