Conceptualizing my own version of Automag Pump Kit

[NONOBLITUS]

Ok so review time. The fit and finish is pretty damn nice. The pump is very smooth. After many efforts to get the kit to work BLachance75 and I exchanged texts back and forth and he noticed a length issue in the pump rod itself. It would not recess back into the rail causing a burp and no shot. I decided to make another pump rod with the same angle just a bit shorter. We noticed that his was 3 3/4” and the one I had was 4” from front of rail to end of rod that hits the bolt. Trial and error the rod I made is now making this shoot smooth and easy. So all in all this kit is pretty damn nice and with a rod adjustment I think you are there. As of now I have put about 100 rounds through it and the kit is still solid. I will be using this on the 24th at an event and will get back as that’s when the real test will be.

Did you use 0.110" drill rod for the rod you made, or is it something else?

[NONOBLITUS]

Hmmm not sure , I will check when I get home today.

1/8th Rod sanded a bit to make smooth.

Will there be an aluminum version in the works at some point?

That is some excellent input, good sir! Really appreciate the time and effort. The pump rod was what gave me the most trouble on my end as well. That’s really helpful that you had another rod to compare to. I will (when I get around to it) make some new rods and give it a try on my end. Looking forward to hear how it plays for a day!

F1FX also had a pump rod issue, which caused his bolt to catch on the rod and rammed the rod into the handle, cracking the hole in the handle. So it’s really good to see that you also had a similarly related issue. Both could be solved by the shortened rod I think.

I’ll be in touch next week after vacation to chat about what we can do next.

Chuck E Ducky there won’t be an aluminum version from me. My MO is typically trying to provide a cheap functional alternative to the nice stuff. Always with the disclaimer “this is plastic, and one step above diy garbage, and may break”, ha ha. But pricing is aligned with that, like 1/3 of the price of a nice metal kit.

not sure if I’ll actually make any of these for sale, as it’s been more of a passion project. I might post the files and a build instruction.

Stay tuned!

And then you get the ugly test prints that work perfect and won't die.

If you do end up posting the STL files they could be sent out to be made out of aluminum rather easily. I like the look of the kit. Can’t wait to try the one you sent Chris.
