On/off pin length

[Tunaman]

The .725" pin is probably the better choice. The .712" pin will function, but as mentioned, it probably won't work well. The .712" pin puts the on-off open point too close to the sear /bolt release point. This works fine for the electronics of the emag, but the human error/finger bounce makes it too unstable when the two are too close together. It causes a runaway situation in most cases. I think that is what Tunaman was refering to.

Exactly. Full runaway with too short a pin. Now as far as Pneumags and such go, well that is surely a custom application and only god knows what size might be the best. The full range of pins goes from like .650(Some Micromags) all the way to .770. Its's anyones guess anymore. What I was getting at was the fact that Mags were designed so that the trigger needs to be fully pulled back and allowed to fully reset in one pull...so altering the pin lengths alters the proper sear lockup and release times on the bolt edge. I am not saying that the pins need to be any exact size, so using pins a few thou shorter than stock should be fine. Too short and you wreck the bolt and sear.

Essentially you are changing the Dwell by altering the pin lengths.
