NIB co2 adapter. I bought it to one day have the option of using my AF guns with co2 but I’m never going to do that. I’ve never tested or installed it. I bought it brand new 3 years ago. I’m including the Tippmann tank which is also new and never used. $75 shipped. PayPal f&f or if you want to use PayPal g&s please cover the 3.5% fee. I’ll ship usps priority to CONUS. Just cleaning up
