Wee Pump

[MAGpie]

This was a fun little project

The "Barrel tip" is a stock feedneck I cut, worked down, and pressed over.






Different barrel, and showing the ASA mounting.




In retrospect, I should have gone with a left feed and normal valve. Would have made the ASA mounting a lot easier. Had to measure it quite exactly so that it does not obstruct the pump linkage rod. But, all turned out perfectly

I like it. Exactly how did you mount the ASA? Hard to see even with the special angle.

Looks like it's clamped to the rail if I'm not mistaken.

Really nice pump pistol. Like need4reebses pistola mags, I like it. Good job!

[Cyco-Dude]

looks like a mini cp rail that's somehow attached to the rail? did you drill a hole in the area the sear goes? rip it apart; interior detail pics of the rail please!

[MAGpie]

Yip, Mini CP directly mounted. Two holes drilled directly into the rail and threaded to standards grip-frame threads. The only issue was to make sure the screws do not go in to deep to cause trouble with the connecting rod. It would have been easier on the other side. I can see a possibility here for a side mounted adapter as well, if someone was to take that up.

Pic is not that clear. My flash is bust and it was a bit dark in the garage.

That's pretty darn clever. I think putting it on the other side would have made it harder to chance the 12g because you would be reaching over the marker. Did you consider at all just putting a short section of threaded brass or something that would have got from the on/off to the valve?

The sides of classic rails take dovetails... didn't any of you have squeegee sidecars way back when?

Yup. Yup I did. Sadly it is gone now. The only marker I wish I had never sold.

spacing is too narrow for modern asas.

Yeah, this is why I think a purpose made one would work well here. As Cyco said, modern ASA's just don't fit so well. Probably due to the fact the the rail has an angle in it. I don't have the machines to manufacture that kind of mount, so I had to go with a drill and tap-set.

No, but I am now :P

No, but I am now :P

LOL. Been there.

Mag's, what ASA are you using?

I think using a mini rail would make it super easy to mount the changer under the front of the rail on the pistol mags, but the ASA would have to be very short with a very flat nose. I will be looking into that.

Wish I knew.... dono. Just one from my box of random parts. It looks the best for the build, so that was my selection criteria.

it's a phat on/off asa.

[bowcycle]

it's a phat on/off asa.

thanks.
