Who makes the fastest trigger?

To answer your question why ask:

I know about geissele, watched the videos, know what marketing is. What I asked is who has the fastest lock time. Not the most reliable, most popular, etc. Fastest lock time off the shelf. The timney calvin elite is measured as one of the fastest and was purchased based on recommendations in this thread to do the research, see what people are running etc. It hadn't occurred to me to look at what the 3 gun guys run and watch the splits. Looking into the subject further, I found where people were outrunning their g triggers...don't like the rolling feel of hiperfire, and found the most success was in the timney providing the pull, lock time, reset etc they were after and could not out run the trigger itself. Maybe it wasn't recommended directly, but certainly was indirectly.

My next planned steps are to replace the ra with a hi-speed NM and recompare once I figure out a good, accurate,, repeatable method of measurement with my current resources. I have a buddy that can send a new one to test with so it did not need to be purchased.

Looking at test fixtures and thinking of using an acoustic measurement system as the resolution I can achieve at home is much higher than a video system without some serious investment.

So why is the fastest lock time important to you if you aren't competing?

[Zeneffect]

The same reason people go and tune a Corvette. Just for fun and self interest.

Franklin Armory binary trigger is the fastest trigger without question. Likely not useful for precision shooting though.

Lock time is noticeably faster on the timney vs the larue or rise armament, just got it out to the range today.

Will give it a few hundred rounds of break in before measuring things.

Might as well spend another couple hundred on a Hyperfire. I bet it will be faster than the others you are checking.

I have used Larue, Geissele Super Dynamic 3 Gun (SD-3G), but my best split times have always been with the American Gold..

I just used my Larue trigger MBT-2S for the first time last weekend in my "precision" Grendel rifle. I don't know about lock time, but it sure is a darned crisp trigger. I'm running the lighter of the two supplied trigger springs, BTW. It's a slightly heavier break than the Geissele SSA-E trigger that was in there before, by maybe 1/2 to 3/4 of a #, but I think it's a crisper breaker.

Titanium firing pins were used in OTC shooting 30 years ago to achieve faster lock times.

Titanium DOES NOT take kindly to work hardening/being BEAT on, as it will shatter like fine lead crystal china ware.

Giselle NM,SSA-E or Trigger Tech in my AR's.....only.

Seems to be a lot of "mixing drinks" in the conversation regarding trigger speeds ... lock time speed is different than a split between shots or binary trigger fire etc. While lock time will still technically affect those things the impact will be in milliseconds.
The only true way to really measure lock time would be with a custom machine which most manufacturers aren't going to have or make. The first one I saw was from Geissele that he brought to Camp Perry back in 2010 or so and he would put your trigger in the machine and measure it and then the HSNM trigger in and show you the difference in a graph computed by the machine. It also showed either consistency or inconsistencies in performance after multiple cycles.

I think a faster lock time can help a bit as it gives a chance to complete the overall firing cycle faster ... in milliseconds. But even milliseconds of gun movement can translate into larger angular spreads on target. That said I still believe that the lock time is going to pale in comparison to the control of those operator induced movements behind the trigger.

The consistency in pull to pull performance in triggers over time would be as much or more concern to me. Thankfully there are a ton of decent triggers on the market today - the GI trigger left a lot to desire in the civilian market.

fast lock time helps with off hand shooting a bit. that being said, im waiting for the G HSNM to arrive.

how to test? 1/4" grid paper, trigger fixture (like the larue or similar.. super cheap), high speed camera on phone and acoustic recording analysis. the methodology for measuring the speed isnt that complicated. Having an all in one spit out a number instantly device seems pricey but if you are willing to do some setup and some math its achievable for under $35.

Arrival, need to pick a fixture and get to work.

I’d definitely say there are other priorities over lock time but to get the data you would need some NASA level shit lol. I use CMC 2.5 pound and CMC 3.5 pound flat triggers. Consistent crisp and butter smooth.
