Regulator for a Marauder

I bought my Huma Air regulator directly from the company in the Netherlands. PayPal made it easy and I had it in 2 weeks. It was very easy to install in my 22 Synrod. So far I'm getting a 3% ES for the first 200 pellets. I believe it will get even better after a few more tins. The reg and a new o-ring kit was only $120 shipped. I'd recommend the reg that allows you to screw in your pressure gauge so you know when your off the reg.
