Airmax MKII is impressive

Out of the box, my .177 was making 745 FPS. In the interest of shot count & noise, I set it at 635 FPS. It sounded about the same as the original version, not so good for fussy neighbors. I put the supressor on it and now it makes little noise. I'm dog sitting for my sister and my cleaning supplies are at home, so I haven't cleaned the barrel yet. With fifty shots or so worth of break in, I'm getting good accuracy. Dime sized groups at twenty yards will make life hazardous for starlings. I'm thinking about a carbine stock for it... that happens every time I get an accurate pistol, LOL.
Time to put out some plinking targets...

The Mrodair mod?

So it's the SLRS mod from Mrodair, and it's easy to attach?

Eight 2.0mm vents holes

Four on each side. Spaced 2" from the breech, then 1" apart, both sides. Makes a difference!

I'm also going to do what Crowpooper did and put some material in each section to help slow the air release.
