    Guess I'll jump in this thread since I have a related question as well. I recently purchased a set of PTP lowers to put on my Tac 1 (I'm assuming they are PTP lowers anyway, they have the humped grip?) When I mount the rail on the lowers, the sear binds and won't function, if I lift the rail slightly it works fine, so I'm assuming I need the spacer to mount PTP lowers on a regular TAC 1 and Rail. Will I need the shorter on/off pin or the regular length E-mag pin?
    What you have are emag lowers. All emag lowers are the same fucntionally. The original ones had the hump and later versions had the straight back. PTP bodies use the emag lowers for micro-emags. The only difference is the sear. If the emag lowers had been used on a PTP body, it may have a micro-emag sear instead of an emag sear.

    If you want to mount emag lowers on a Tac 1, they just bolt on. No spacer is needed. The emag sear replaces the one in the Tac-1 rail as long as it is an emag sear and not a micro-emag sear.

    You will need a 0.712" on-off pin and a quad oring for the on-off in the valve.

    When mounting the lowers on the rail, make sure the trigger rod is going into the proper slot and that the plunger is the correct length. The length of the plunger should be 3.005" from the clevis to the bottom of the plunger. Also make sure that there are no bends in any of the rods.
    Except for the Automag in front, its usually the man behind the equipment that counts.

      I never knew there were differences in the sears, I assumed they were all the same and the shim was due to tolerance issues. I'd actually like to see this sear you have if all possible.

        The body shim is due to the differences in the body dimensions.

        The micromag body takes the same sear as the classic automag rail. An emag sear needs to be modified to fit. The sear is a regular emag sear that has the bushing shaved down and drilled so that it is flush with the side of the sear and fits the micromag sear pin.

          I took out the sear to measure the plunger, and it turns out my binding problem was because the plunger rod was bent. Straightened it up and works just fine.
