Umarex Zelos arca rail

Has anyone tried 3d printing something or made something to fill the void *see picture* that also attaches to the tank and an arca rail of choice adding way more rigidity and stability. Not a fan of using just the trigger guard and one or 2 mlok fasteners like I see a lot of people do. Having solid connection to the tank and trigger guard would greatly improve how the gun can be used with bipods and tripods as well other accessories. Arca rails are just far more superior than picitinny. Just a flex I hand pumped that 500cc tank, not as bad as people make it seem, span of 3 days I think 4-6 pumping sessions total that were only about 10-15 minutes.

“Hand pumped a 500 , not as bad as people make it seem“
haha hoho, man I must be near death. My 50 ml Reximex pistol
tank had me rushing to amzon for a cheap small compressor.
Hahaha I did say over a 3 day period, the bottle conversion should get me 80-100 shots like what most people say. I'm not shooting everyday and taking that many shots. But if you had a big day of shooting or did some competition stuff yeah and pumping is not really ideal. A compressor is in my future, it's just that people made it sound impossible to hand pump a tank that size.

I am looking for info on rails. What is that on yours and how is it mounted? Maybe point me to where others have already had this conversation? Thanks.
 
Nice work! Are you planning on a version with pic rail?
The lower rail in that photo has an Arca rail with Mlok slots on the sides and bottom. I figured if I wanted a pic rail along the bottom I could grab one meant to be mounted in the mlok slots. My plan is to utilize the mlok slots down the sides to mount the bipod legs in the photo.
 
Yeah I get that, and it looks great with the M-lock bipod. I’m just saying if you’re planning on producing them to sell, a lot of people already have pic mount bipods so they may not be as interested know they would have to purchase another bipod for it to work for them.
That's a fair point. It could definitely be done as another option. I've redesigned the trigger guard to provide a ridgid mounting point for the lower rail anyway so having a lower pic rail option wouldn't be difficult. Honestly, I hadn't even thought about a lower pic rail other than an mlok mounted system. Thanks for the feedback I will keep that in mind.
