Huma Regulator for 2021 Marauder .22, Synthetic Stock

[rlp]

I have a couple question regarding the Huma regulator part 1124 and Plenum part 1259

1. The regulator part # 1124 came without the m3 screw shown in the instructions. Is the screw missing or is this a design change? Without the screw I do not see a way of attaching the recommended fishing line to assist in removing the regulator to make adjustments.

2. The regulator arrived with the pressure adjustment screw turned (seated) all the way in, so the Huma instructions not to turn it past the lowest setting don't seem to apply. Maybe the Regulator missed Huma's QC, I have not been able to find instructions on how to set a regulator that was not preset from the factory. Thinking I probably should return it.

The parts did not come directly from Huma but one of the larger US supplier for Huma-Air. I would appreciate any thoughts or suggestions.

Thank you,

ive messed with 2 regs so far and they take alot of tinkering .. ive decided they really arnt for me lol ... if you want to try it, first be sure you can remove it to adjust ... then you need a full bottle of air and a degassing tool and start backing the screw out 1/4 turn every time and filling the tank and dry firing a time or 2 to see where its at ... wash rinse and repeat until you find where your at ...

E- mail Huma and ask them. If the screw was in the bag, it may have come out and you didn't see it. You can by a M3 stainless screw. I think they say not to set below the lowest setting when under pressure.
