Seeking advice on AR drop in triggers to replace a creepy mil-spec unit.
Brand & model?
Two stage, or single?
Pull weight?
Curved, or straight?
Thank you.

JP drop in modular trigger, clean single stage break, comes with two springs red/yellow, red gives about 5# and yellow went 2.5# on my AR. It’s pricey but buy once and cry once. Comes as straight drop, curved or straight drop roller trigger shoe, you decide which you want, also comes with ambi selector lever.

The trigger tech drop in is outstanding.

Maybe I'm using the wrong terminology. Unfortunately they have been sold out for a while. Anyone care to comment on differences between 2-stage & single? I know what it means, but I'm not sure how it relates to an AR type of platform.

OK. I learned the difference between "Drop-In" & the Larue parts.

I know what it means, but I'm not sure how it relates to an AR type of platform. JM here's a way the single and two stage was told to me. On the two stage you have the first stage with the take up slack, then the second releases very easy depending on what your trigger was set at. With that said say you have a target lined up (hunting or just target shooting) and you pull the first stage, but then change your mind, so you release the trigger and nothing happens. Where as with the single stage there is no warning, like the slack of the first stage on a two stage trigger, and depending on how much pressure you put on the trigger it may have been enough to fire the rifle. Personally I like the two stage. Lot of people don't know this or don't say much about it, but the AR10 uses the same trigger control group as the AR15 and it didn't use to be that way. The firing pin on the AR10 is much more robust and heavier and the original AR10 had a heavier hammer and hammer spring. Some of the modular drop in AR15 trigger groups, in my opinion, don't have a hard enough firing pin hit especially if you have hard primers in loads. I recently built an AR15 22 magnum rimfire and I swapped out the drop in trigger for a the standard AR15 trigger group because it wasn't setting all the 22 magnums off because it wasn't hitting the rim hard enough. Something to think about.

I know what it means, but I'm not sure how it relates to an AR type of platform. To me a “drop in” trigger is a once piece unit whereas the LaRue is a traditional two piece install. Does that make sense? That being said my LaRue physically dropped right in with no issues. -Stan

Have several of the 3.5# CMC triggers and could not be more please...zero issues.. Curved trigger/single stage.
Also have one Timmney 3# single stage curved in a DPMS Sweet 16 and no issues there either...

*****
The two-stage goes back to the late 1800’s. May not have been invented by Peter Paul Mauser, but suspect he was close by. The first stage of pull is designed to make the lockwork drop-safe with the safety off. Good examples pretty well much do this. Bolt action rifles from WWI & WWII i’m familiar with have a 2-stage trigger. Autoloading mechanism put new impetus on the concept, and John Garand borrowed John Browning’s ingenious hammer-hook from the Browning Auto-5 recoil operated shotgun of 1900 for fire control in the rifle we know as the M1 Garand. Both Mauser and Browning 2-stage triggers are “open”----dirt resistant----mechanisms which allow for the clean break second-stage so conducisive to marksmanship. The second-stage concept was put to a harder test to prevent slam-fire----especiaslly when the gun is dropped----in a submachine gun which fires from an open bolt.
Browning brilliant Auto-5 trigger prevents full-auto fire when the recoiling barrel slams forward, with bolt carrying loaded shell right behind. This does not prevent a loosely held Auto-5 from doubling, or tripling, etc.; which is operator error, as the trigger resets on recoil and pulls away from the trigger finger. Yet, the long recoiling barrel jolts the shotgun forward as the barrel slams into battery, pushing trigger against finger.
Biathlon (cross country skiing combined with marksmanship) rifles feature 2-stage triggers with letoff measured at a few ounces. There is no safety on the rifle, it is loaded & unloaded on designated firing lines only. The high degree of accuracy must be consistent on all targets to avoid a penalty lap added to each miss. Extreme cardiac does not allow for the “surprise break” prized by static shooters. The target doesn’t move, but the shooter moves, so the shot is TIMED by SIGHT PICTURE, not surprise break. A heavy trigger makes consistency in this kind of marksmanship nearly impossible. The single-stage trigger is out of its league in this game. A single stage trigger cannot be tuned light enough, nor can the shooter be tuned light enough. David Bradshaw

Geissele, LaRue, and Timney are all good triggers. There are multiple levels of triggers depending on it’s purpose, your preferences, and budget.

I've been happy with CMC triggers, but can't say I've tried a lot of others.
They are perfectly good for what I need in an AR, which is hunting with a thermal.

I really like the Trigger Tech 2 stage. I got it on sale at Midway for about $125.
My next preference is CMC. That is what I use when wanting single stage. They also go on sale and are even more affordable.
I do not like my Geissele (sp?). Over priced and does not feel as good to me as the above.

Not a drop in, but I only use Geissele SSA-E triggers in my AR lowers as I want the same feel and trigger pull in each of them for hunting, target practice and shooting in matches.
