Just got mine in today, Using it with an Arbiter 2 with straight glass (26mm) and it just squeezes in.

It has a good weight to it but not too heavy, and the fire button for me is a lot more comfortable than the Paramour style side button.

Battery door a little thin and fiddly but not as bad as some.
and sticker warning you to not over tighten the battery door uses the sort of glue that wont let it peal off in one go.... isopropyl alcohol on a piece of kitchen roll sorted it :)

A great little stealth mod.
