Cheers cammdy. That was the idea behind the build. Have a fully functioning gun, keep cost low, safety as high as possible and some thing most dumb asses can build with basic hand and power tools (dremel, jigsaw, bench grinder, hacksaw, drill and router)
Like I have never extensively used a router before, seen it done plenty of times so... most of it was by eye
no real measurements to start lol of course I used the guides and depth gauge. It actually poppped together seem less the first time
only wonky fittings saw the need for re-working.
Having test fired this I'll leave it this length plus silencer as it intended use was just a hallway plinker -10m, even though its capable of much more than that. I have built Bb trap out of a box filled with towels and cut a price of thick foam that seals back of box. Even at 200psi 10m its 100% effective, just shake the first sometimes second towel out in the box and collect with magnet
I make my own shoot"n"see as well using the fluro backing paper, contact or clear packinging tape cover entire area then $3 spray paint. Making squares with bulls eyes or cut out birdy or rat shapes.. or a nice sillouette of your old boss, endless really
WARNING I do not recomened shooting indoors to anybody! I do it in a well controled/setup environment. I take no responsibility if anyone makes anything I have mentioned and it fails. I test all of my work/bulids outside and by remote.
So it shat on my precise double sided tape application 
So Its kinda back to the drawing board although I have it nutted I just got impatient..

All shots at 10m outside
