Umarex Zelos pics ..

I just received my Zelos .25 from PA and it weights 7.29 lbs filled with air. No mod or scope or anything else has been added.

For a 6 lbs gun, could adding air add that much weight? Other than the weight, the Zelos is shooting fine.
Congrats on the new gun.

It’s 7 lb gun. +\-

Post a pic here when you scope it and mod it

Replaced the moderator with the DonnyFL Ryu (added 2 extra baffles to quiet it down a tad more) which shortened the OAL from 36" to about 34". Also added an offset scope mount to help with the ridiculously short eye relief on the Discovery scope.

You guys are making me jealous. @Firewalker is fabricating a compact .25 for me right now. Or at least I hope he is, haha. I haven’t heard anything for about a week.
I also have an M60B in .30 that I’m waiting for a caliber change kit on to change to .22
The hammer spring should be the same in both right? I’m wondering if I can do the spring mod in the M60 and it will work the same in .30 and .22
Obviously I would need to adjust the reg but aside from that what do you guys think?

Much better. 36 is to close to its stock length
This one looks tight now !

Tell me about that bottom rail
That rail has an integrated arca rail with Mlok slots down the sides and bottom. I redesigned the trigger guard to provide a more rigid mounting point. The rail is 11.5 inch long from the back of the trigger guard to the end of the rail. This is the first machined prototype so a few things might change cosmetically speaking, but the rigidity and function are spot on what I was looking for. In this version it's a two piece assembly, but the discussion for making it as a single unit has already started. If you look at the photo close enough you can see that it has arca rails bolted to the lower mlok slots because we had to order some tooling to finish milling the arca rail. Works perfectly for pictures, proof of concept, and design feedback.
