Even though I cut my finger open trying to open it up after venting the first two CO2 bulbs (because I'm an idiot who can't work these things out), I love the Wraith CO2 adapter. I'm just going to go out there and say it. This new VSR build with the Wolverine Bolt and Wraith CO2 adapter is my new favourite. Hands down. It's so good and is so easy to adjust the power to match the joules you need for your local site limits, or even run it as a 1J sniper and have no MED.
Though, if you're getting one, make sure you have a set of Imperial measurement allen keys. Metric ones won't work! Found out the hard way when I forgot my set when I went down to the range this morning 🤣
