Did some work with My new Airmax pistols! Some simple mods too

So i finally got the time to get this gun set up!
First up was a simple yet very effective fix for the barrel spinning
I drilled and tapped the top rail to 6/32 and used a set screw
Barrel is centered and doesnt budge when the SLRS is installed
Second i drilled a hole on either side of the reciever for some pressure to disipate resaulting in quieter operation.
I also added a roll of scotch brite to each segment of SLRS

I also added a Centerpoint multi Tac
I used dremel to loading gate area of grips its a TINY bit high not fully allowing gate to drop flat open

I backed out the HST nut
Both mine and my fiances guns are in .177
A fill of 3000 gets me 40 shots between 593 and 602 with an ending pressure of 1100
This is using JSB exact heavies
Accuracy with the multitac is pretty good
At 25 yards nailin the 1 in spinner 99% of shots
Its quiter than a staple gun and very back yard friendly
We shot 400 shots neighbor was in his yard and didnt know we were shooting until i told him we were.

So far loving the gun!!

Inside the shroud or something like that? Haven't noticed anything odd with my .22 version like that so far.

I see what you mean now

Had to disassemble my whole pistol since the regulator froze up after loosening it too much and wasn't allowing shots to go through at all even after seemingly tightening it again. Once I got everything apart I definitely saw the issue with the free spinning barrel. What was interesting is the little bushing with the green oring seal in the main body of the gun that the barrel screws into has two flats milled in it so they could have set screws going from the sides of the gun into it. May make use of that tomorrow.

I did one hole either side

Worst case a dab of gorilla glue and a sharpie its filled back in
As is at 8 fpe this gun is very quiet.
