Works great, bolt locks back when mag is empty. It has been lubed and maintained throught it's whole life. I couldn't have shot more than 1000 bbs through it. The NPAS is set around 400fps but can be adjusted easily (will include key). Has a reaps bucking (adds range) and an angry gun recoil kit (adds recoil and rate of fire is adjustable). Shoots very far and accurately. I also did a mod to the nub to make it hop even super heavy bbs. I normally used .30s with it. Comes with 2 mags (no leaks). I can add an Angel Custom Steel 300mm 6.01 barrel for an additional $10. (Will add another bucking that fits the barrel). The 300mm tightbore sticks out a bit. The stock barrel (around 280mm) doesn't. Price is shipped. Will ship priority 3 day mail. Will send more pictures and shooting video upon request to serious buyers. Any questions, feel free to ask. Thanks for looking!
