    I plugged it with Luke's adaptor to my rail after making two holes.

    I want a single battery to power my warp feed and my loader. It is to contain it... but I am not there yet.

      you need to read my posts. somewhere around here I have a lengthy post with all the info on why you need to use a sear stop.

      first you don't want the sear slamming into the bottom of the on/off. the sear is harder material and will eventuallty distort the pin hole in the bottom of the on/off causing poor performance. trust me.

      also it wastes more air by having the MPA -3 acuator travel farther than need be. this is not much air, but the smaller the amount the better. this way you don't really need a QEV if you do everything you can to reduce air consumption.

      it also slows your recharge rate to have the pin travel too far up into the on/off when you don't use a sear stop.

        In between the point where the sear releases the bolt and the point that the sear hits the bottom of the on/off, does a sear stop act like a shim in the on/off? Since the on/off pin isn't going all the way up, it's kind of like having a short pin or shims in the on/off (?). I guess the timing is different though.

        A short pin would seal later than a longer pin pushed less.

        What is the normal end of travel for a mechanical trigger on a mag anyway? The back of the trigger or the bottom of the on/off?
