Just put this together
Removable/adjustable stock not finished and no sights yet. Going to get some telescopics.
Single shot with reload, ammo tube holds 20 1/4" steel balls.

The ammo tube looks weird but nice reload system.
If I were you I'd weld the stock holder on the other side of that plate, so the stock and barrel would be linear.
Is this just a pressure washer handle and a barrel? What kind of damage are you getting out of this?
Yes the plan was to have them inline, but this way I can slide it all the way in, and the offset doesn't really hurt too much as I am right handed, so it kicks the main body of the gun to the left.
It is a pressure washer gun with 1/4 ID stainless tube, that's 3 I've used now to make air guns, no idea of damage yet as I need to make a good target setup, do get sparks if I hit the concrete floor though.
Steel 1/4" balls, but it would fire airsoft as well. Just using 100psi from a small compressor, that seems plenty for what I want. I put airsoft bb's in my full auto and it was quite impressive, I am making a hopper for it that will hold a couple of hundred.
After some modifications here is the latest version of sniper, I can reload with left or right hand, no sights yet as they haven't arrived. I have done a short video as well, was about 12feet from the target and did 4 seperate groups on the target. Bipod worked out quite good, legs fold forward or backwards. Ammo tube holds about 50 balls, I have various lengths of these.
Damage close up
Video, 2nd group had ball go through the same hole, nearly on the 3rd group as well. Will be interesting to compare when I get the sights on.

Reason: Fixed video.
Updates and modifications
Can you do me a favor? Shoot at point blank at a coke can and the chart below tells you the fps based on where you shot and the penetration you achieved.
ONE SIDE 290-310 fps
BOTH SIDES 350-370fps
BOTTOM (CENTRAL) 420 to 450fps
BOTTOM (EDGE) 450 to 480fps
TOP (EDGE) 480 to 510fps
TOP (CENTRAL) 520 to 540fps
That's interesting, just a standard aluminum can I assume, I have a stack of those ready for my Tin Can Alley.
Do these figures depend on the weight of the ammo? I am using steel, Airsoft bb's may have a high fps but I would guess less penetration due to less mass.
Ya use an .2 gram air soft Bb, and make sure the can won't move around when shootimg, tape it to the ground or hold it in our hand
It has to be a .20g. Just an Al beer/soft drink can will do.
Since I've got a chrono, I really should set up a standard for .25s and various other targets.
Odd choice of target but nicely done. I love the reloading mechanism!
I would really suggest moving to a QEV/3 way valve to ensure more consistent performance if "sniping" is your goal.
Otherwise staying with the pressure washer unit, you should think about hooking it up to a paintball bottle. Running it on 8 times more pressure will be a revelation in terms of power
I have .12g airsoft but I may be able to get hold of a few .2g.
Anywho it's just a bit of fun for me, something to pass the time on my long night shifts at work.
Wow!! theres some really nice Guns on here lately this thing is Boss and the reloader is definitely unique!. if im understanding the reloader you have used a T Piece and at the bottom you have a steel rod that blocks off the next bb from rolling into the T Fitting?.
But how have you managed to get that rod to be airtight in the T Fitting?
