My little Tac One project.

So I have a Tac One and I don't like hoppers and longbow mags cost a lot...so I decided I was going to try something.

Someone local was selling a Rap4 P68 pistol with a few mags so I asked him to part one.

This was my Idea.


It looked like it might fit so I started cutting!


A short time later I was done


And it fit! Quite nicely too!



This is what I see from the back.


Then I went to test it...and the macro fitting on the bike grip Blew!


After I changed my pants I experimented with a few different ways to route the air source...and finally I have half settled on what was originally my vision in the first place. I mounted a 3.5oz strait up to the VA...however the burst disk would not clear the trigger frame so I had to use an ASA extension. It works...but it is not exactly ideal, the extension I have is about an inch and a half long and makes the 3.5 hang a bit low...it will do for now until I come up with a better solution.



Tested this out with Reballs...but they didn't want to feed very well. Hoping its just the Reballs...

Still to do:
-Drill a hole in the spring feed for a side feed port!
-Try not to sell the whole dam thing...
-Anno? (After a lot of other bills are paid)


And as a bonus...I discovered enough other spare parts to build a second mag!




Complete!

You'll find that happens a lot...or you just need to buy one more part....which turns into more than one part

With the reballs, if they aren't oiled, my mag has problems shooting them too. You could try putting a tank oring in the vert Asa and see if that spaces it out enough so the burst disk doesn't hit the frame.

I will try the Orings...I am not sure why that did not occur to me...seeing as I did it on the extension to make the port face out...

If this works I will be over the top!

Yeah the reballs seem to be just sticky enough that they don't want to slide down the delrin of the feedplug.

Nope, Orings didn't work...Couldn't screw the tank in far enough to get the pin to engage the tank

Ah, guess your only chance is either that or get a longer vert asa, or shorter extender.

hold on, maybe we're thinking about this the wrong way? Can you not space the ASA lower from the rail with an oring or two, or a washer?

this might sound like a lot of work but you could assemble the tank on the ASA and put on the frame, and if your ASA has a port on both sides you could build a quick disconnect fill nipple setup for it and fill it on the marker. You would want to add an on/off in your NPT setup going back to the valve to prevent problems there. Then it would be short, that or maybe just swap the valve on the co2 tank for something a little longer, there are some odd valves out there.

This seems like the easiest solution

I was thinking something along these lines as well. What makes it difficult is the ASA is mounted with two screws...

This is an interesting idea...but the ASA is not tapped on both sides .

The easiest option would be to get a standard AM/MM rail and ASA...
