    On a side note. The "Ahhh/Ohhh" at the beginning and end of the video just about had me spraying coke all over my monitors.

    DING DING DING WINNER!!!!!!

    It's exactly how a pumpmag works. All we (my machinist Mr. Bill and I) did was mill the emag rail exactly like a normal pump milled rail is, however there it stops right before the front of the rail. There's a slot then cut completely through the rail for the pump rod we bent to connect to the pump handle/battery box.

    It uses a wave spring just like any pumpmag would however I had problems using all forms of bumpers because the sear wanted to ocassionally reset onto the blot.

    The pump handle battery box is completely handmade with a guide rod in the bottom that goes through the frame only when pumped to avoid binding. There are also 3 return spring voids cut into the handle to allow it to spring back.

    The original front thumb screw was replaced with a custom made one with a wider shaft to allow the top to also be used as a guide as well.

    The only thing I did that may "wreck" the value if ever sold is the hole drilled in the frame for the lower guide, the pump milling, and the body milling for pump rod clearance.

    As far as internal pictures I still don't plan on taking pics right now... Maybe in a bit.

      awesome you had us all fooled... I would guess the same mod could be done with out the use of emag lowers But that wouldn't look as cool

        Oh trust me it was hour upon hours of trial and error. Finally we have it to a super smooth pump stroke.

        If someone owns a pumpmag, actually check the activation point of the pump stroke... It's only about 1/8 of an inch. It's only as thick as the wave spring. That's why in the videos I only pump it ever so slightly, that's all it takes.

          True. But in order to have the rod out of the way of the bolt your pump stroke has to be longer.

            negative. If you change the degree of the pump milled ramp the rod slides up, 1/8 is just enough to push the bolt and then move back down to avoid the bolt slamming into it.

            Trust me I did it

              The clue that gave it away for me, was the fact that you said you could easy revert back to regular emag. The only way I could think of doing that would be to just remove the wave spring.

              Does this mean you're going to send it to me for guessing right? It never hurts to ask, right?

                Well if you changed the milling then I would agree with you. But earlier you said this v v v v

                  Ok ok it's more or less a spin on my words but yeah. What I meant by exactly like a pumpmag milled rail is where it's located and how it functions. If I was getting technical I coulda said it's also .003 difference in depth as well.

                  Not only is my pump rod thicker than the original it's also longer.

                      I'm just squeezing info out of you for my emag pump build

                        Shot this wonder of a marker today. Super smooth and hardly any effort to pump. Would shoot again lol

                          im sure the marker shot great! but the user of the marker likes to take my shots directly on his nipples... just saying

                            His nipples are sensitive but I think he secretly liked it. He also took that shot after he was out. I was also shot after I was out by the same pube fingered trigger happy turd but mine was closer and in the calf. It was also my backup gun as well that you where using and I had to clean it as well. Next time you get to use the trilogy
