Pump Action Reloaded

[farcticox1]

So here is my much awaited (by me) pump action, firing 1/4" steel BB's. Magazine holds 20, slide mechanism moves about 1/2" and as an added bonus if the slide is held back you get full auto

Everything hand made, mostly aluminum, slide is stainless fabricated out of 8 pieces (I made it too short first attempt)



It started as a pistol but was too heavy for one handed use, so it got modified.





Adjustable 'Layzor'



Return spring hidden inside the handle.



Here's whats inside the slide

Wow that looks nice
So according to your drawing every shot takes 3 BBs?
If the magazine has a 90º bend instead of sticking off it would look so much better, or make it round like a drum mag.

[farcticox1]

No, it only fires 1, I think the other 2 are pushed back down by the pressure.

No, it only fires 1, I think the other 2 are pushed back down by the pressure.

Interesting, the other 2 should be supposedly "sucked up" duo to venturi effect. However I'm glad it works

[farcticox1]

I think a slight leakage through the slide keeps a positive pressure inside, the only oddity is when the plunger enters the slide and jams it open, you know it's the last 3 three shots, they have to be fired as auto with the slide held backwards.

doesn't sounds like a big problem I bet it's a lot fun

[hawktalk]

any chance of a shooting video?

[farcticox1]

Yes, I will do one at the weekend and get the Layzor dialed in.

What kinda power? Also what's your valve for firing. Is it a blow gun or something? Sorry if I didn't catch it in previous posts.

[farcticox1]

Yes it's my favorite pressure washer trigger.
I'm guessing power similar to my long barrel version, will go through the bottom of a pop can and dent the top, no exit. Straight through side on. This is with 100psi, the trigger is rated for 5000psi so there is room for greater damage.

[tigerblues28]

Oh okay cool. I may just have to make an airsoft sniper hmm? How much did your pressure washer cost?

The trigger was my favorite price, free. Got it out of the scrap bin at work, the plastic cover was gone and it had a fitting snapped off in it, but I have a good stud extractor that got it out.

This is what it should look like

They are not that expensive, and you can get them with a barrel
ready made spud gun

[farcticox1]

Might make some cosmetic additions and folding stock, something like this.

YES!!!! you got the Pump Action to work, im hopeless and haven't even had time to start mine .

Well done mate

Indeed modify it as pictured in the above post

[farcticox1]

So it seems wyz2285 was correct, it is firing 2 shots at once, I will try and fix this, hopefully simply.
