Gisselle DMR shooting doubles?

[deersniper]

Can a gisselle DMR (adjustable) trigger be set to shoot doubles?

I know if you set a bolt action trigger too light, it will fire when you close the bolt. I don't want a trigger that can be misadjusted so it shoots upon trigger pull and upon bolt closure.

EDIT: MY TRIGGER IS GREAT. IT IS NOT SHOOTING DOUBLES AT ALL.

I just don't want a trigger than can be adjusted to malfunction. I know the ATF has "odd" definitions of a machine gun and don't want any risk of problems in the future. (IE: you can turn a few screws and have a "machine gun". According to ar15.com, the trigger cannot be adjusted to shoot doubles.
Thanks!

doubling is usually a result of the shooter "tapping" the trigger and upon recoil it pushes the rifle back into your finger causing it to fire.

Is this a 308 ?

If it is truly "doubling", something may be wrong. However, depending on how low you adjust it you may think it is doing this.


When I was messing with mine (in an AR10) I tried the 2nd stage at just a few oz (the minimum) and it proved extremely difficult to not just "pull through" the 2nd stage due to the 1st stage being about 1.2lbs. If I would indadvertantly pull through and suprise me it did double once or twice due to the extremely low overall pull weight. It did this because the pull weight was so low that the recoil of the shot set it off again before I could release the trigger, sort of like a short accidental "bump fire". Needless to say I put it back to a 2lb 1st and 1lb 2nd stage.

Like folks have said, doubling can be shooter error or trigger adjustment error. I won't get in to shooter error or problems in proper trigger manipulation, but the DMR can absolutely be improperly adjusted for both sear engagement and the weight of pull on the 2nd stage. I have done the same thing as Falar in terms of the weight on the 2nd stage, but I didn't experience any doubles because I increased the weight before I went live with the rifle.

If you follow Geissele's instructions for the adjustments (especially sear engagement/adjustment) and you don't go crazy trying to get the trigger to operate at too light a pull weight on the 2nd stage, they are extremely reliable triggers that shouldn't cause you any problems.

Triggers need to be non-user-adjustable...

One of the many reasons that the Geissele SSA and SSA-E triggers are FAR better options for 99.9% of the people who buy aftermarket triggers and install them on their own without professional assistance. No fuss, no messing around with adjustments, no user-created unsafe settings...just a crisp, clean, reliable 2-stage trigger that you can drop in within minutes and be back on the line shooting.

For what its worth, I had no intentions of actually trying to use a trigger set to a few oz. It was more of an experiment after I listed one for sale and someone made a comment to the effect of "If it only adjusted lower I would buy it in a second".

Well, IMO it already is adjustable enough to go too low to be used effectively.

Why? I have never heard of any problems with Gisselle adjustable triggers causing problems of any sort.

Thanks.

Lowlight can chime in here on his take about adjustable triggers, but from my experience it is user/installer error that creates problems with adjustable trigger units...not the triggers themselves. The problem is the high number of unqualified people doing "home gunsmithing" with no real understanding of what the hell they are doing that can cause problems, especially with safe and reliable operation of the rifle that the trigger is being installed in.

The Geissele's adjustable triggers (Nat'l Match, DMR) are not exempt from being adjusted to unsafe conditions by those same unqualified DIY guys, including but not limited to conditions wherein the trigger will double whether it be because of user error/trigger manipulation error or trigger malfunction because of improper adjustment or a combination of all those things.

As for legalities of the trigger and ATF concerns...I wouldn't worry about that in the least. While the ATF can be anal about some things, the Geissele DMR trigger was not designed or manufactured in such a manner as to easily or readily render it in a condition that would violate federal laws or otherwise render the rifle its installed in subject to the NFA regs on MGs. Your trigger seems to be functioning normally and without any signs or symptoms of doubling or other unsafe operation, so you are GTG.

As for the ARFCOM thread...I haven't seen it and don't know why people are saying absolutely the Geissele can't be adjusted to allow it to double, but I take issue with that broad a claim. As I have said, whether it is solely the trigger or a combination of the trigger and operator error, you can and will get doubles from a DMR that is improperly/unsafely adjusted.
