Well, not new, but a revised version.
The Huma first stage reg for the pre M3 Impacts.
I just got this installed a week or so ago and I’m still undergoing tests, but judging from how the gun shot before this mod, here is what ive noticed-
1. Quieter for sure
2. The “sweet spot” of 230 bar down to around 180 bar is gone. From 250 bar full fill all the way down to 180 bar the gun shoots and performs the same.
My factory Mk2 reg is currently set at 130 bar. Even at that setting, in the past I always noticed the gun didn’t get “in the rhythm” till around 230 bar and somewhere below 180 bar it lost its snap. Hard to describe, as the tuned velocity was still good till 130 bar, but it just felt different. From the rapport, to the slight kick, all that changed as the air pressure went down or if it was at a full full.
With this first stage reg taking the bulk of the load(as all M3 owners benefit from), my impact handles like a dream. I also noticed although my shot strings vary in the spreads from tin to tin, I don’t get the 940, 935, 912, 945, 928, 960, etc(like where did that 912 and 960 come from?!)
Best things I like about this upgrade on top of better consistency is the new fill location along with the quietness that came with it. I use a huggett snipe and it works well, but that snap shot noise seems to have tamed a bit, which is always a plus.
So, let’s talk about why I say this is the revised version.
Huma came out with a first stage reg a couple of years ago. In my research what I learned that did not appeal to me was the fact that the entire bottle had to be drained of air if you needed to pull the bottle off to adjust the first reg which was within the bottles adapter mounted on the trigger block(same as an M3. Plus, at what seemed to be like 3” in length, I didn’t like the look it gave with the bottle moved that far forward.
So here’s version 2-
Total length and the amount it moved my bottle forward was a mere 1 5/16”. The machining work is flawless as most of humas aftermarket parts are, and the fit up is tight, meaning, it looked like it was meant to be there out of the factory.
Tge install procedure was super easy, just take your time and read the instructions well. I’ve noticed over the years Huma has been more detailed in their step by step instructions, with more pics to boot.
Here’s a copy-
I’ll let you all read up on the specs and options that you have in gages and gage location, but I opted to have my gage on the right side next to the factory fill pressure gage, that now becomes the first stage reg pressure. For my 25 cal my first stage is set at just a hair under 200 bar, and on my 22 cal impact it’s at 160 as it came from Huma. Adjusting the first reg is as easy as all Huma regs are to adjust.
So here are a few pics of the Huma Reg installed. The new fill port is now relocated to the left side, and the Huma kit comes with a plug to close off your factory fill port location-(pics at next post)
