Marauder Marauder Huma Air Regulator

[mhew]

any ideas why a huma regulator on a gen 1 .22 marauder would be far more spread than the unregulated setup? Also with the huma regulator installed the marauder factory fill gauge immediately stops reading accurately?

The gauge is reading the regulated pressure after installing the regulator. If you want to see the fill pressure you need a second gauge. The easiest and cleanest option is to install the HUMA quickfill assembly for the Marauder Benjamin Marauder Quickfill Set With Pressure Gauge By Huma-Air which replaces the male foster fill assembly. It will come with a fill probe. Not a big deal in my opinion but for some people it’s the end of the world and life as we know it to have to use a fill probe.

More to regulating a rifle than just installing a regulator. You’re likely getting hammer bounce and wasting air if all you did was install a regulator. The hammer is too heavy and the spring is too strong and causes the hammer to bounce on the valve stem. Getting the hammer in free flight by making a spring stop guide (SSG) will help. Free flight basically means that the hammer does not have any pressure on the valve stem when the rifle is not cocked. Using a lighter hammer also helps.
I suggest searching old threads on GTA . A lot more information about the different ways to eliminate hammer bounce and tune a regulated Marauder over there. Good luck

any step by step instructions out there for correcting hammer bounce and making a spring stop guide?

I had the same problem…I was not impressed at all with the huma, I threw it in a drawer and forgot about it….i went with the archer airgun mod. Excellent product

@mhew WOW, thanks! You mean our Marauder Tune Kit? I'm glad that it has worked well for you

I find the marauders are confusing as …… having a hammer travel, hammer spring and add a regulator it’s like triple confusing. That’s just me. They’re consistent enough without a regulator

I haven’t put a reg in a .22 Marauder. Only .177 Marauders. All were Huma regs. The Huma reg by itself will not work right. You need an aluminum hammer and a lighter hammer spring. Do those three things together it will work great. First buy the aluminum hammer and install it and try it out. It’s a big improvement over the steel hammer. It reduces hammer bounce and increases your shot count. It’s also easier to tune. If you still want a reg then get the Huma and a lighter hammer spring.
