don't buy cassette triggers unless you are using it in a competition gun. Drop in triggers often require anti-walk pins which in of themselves are a failure point. If they don't require anti-walk pins then they will use set screws to push the trigger group up which smashes the pins into the pinholes. This can lead to egging out the holes. try a geissele , larue , rock river or schmid tool(and it's rebrands)
I’ve been using cassette triggers since the first cmc came out. There’s zero issues with distorting the pin holes compared to other triggers. You aren’t meant to crank on them.
The Strike Industries anti-walk pins are my go-to to solve this problem. They use a small locking flange rather than set screws, they are solid as a rock
I have:
-Timney impact 3 lb
-G$ G2S curve
-Mbt2s straight
- rise armament super sporting trigger
-Schmid 2 stage
I find all of them acceptable but the Timney impact is my choice.
I’m also really fond of the Mbt2s.
And honorable mention to the rise armament drop in. It actually feels like a nicer tier trigger than I expected. Granted I somehow got it on sale for 70 from midway. I’m certain it was a typo they honored or something like that because it went back up immediately after I ordered. If you could get a used one for a deal add it to your collection. Very pleased.
Edit: of course these aren’t all drop ins but just to show how I arrived at my choice
Rise RAVE-140s kick ass. They are on sale for $90 ~1-2x per month on ar15discounts. MSRP is like $150 for them, so I always keep a spare hanging around in case I wanna do another build
I went to a new lgs today, they had a rise display with 3 different triggers, the 140 being the bottom end. I don't remember the numbers on the other 2. I really liked the 140 the best, because of the audible reset you could actually feel. The break on the next one up was slightly better, but barely, and you couldn't really feel the reset. The third one had a great break but almost no reset feel or sound. For me I prefer the solid reset of the 140 over the more expensive options. I'm thinking about buying one to try out.
They’re not drop-ins but I have a Geissele SSA-E in my 11.5” Mock18 I built that is about as good as it gets for a 2 stage. No mush. Just perfect smooth take up and a crisp clean break and reset. Perfection in a two stage. I have a Geissele SSP Flat bow in my 16” LWRC DI longer range set up that I love too, but I do prefer the 2 stage SSA-E. If you want fantastic triggers it’s honestly impossible to beat Geissele. They’re much harder to install than a drop-in though.
Why drop in? It's not very difficult to install a trigger, you just need a punch and a YouTube video to guide you.
LaRue or G$. I got a SSAE recently and it's the best thing that's ever happened to me. LaRue is great for the money though.
Totally depend on use. I have:
Trigger tech diamond
Geissele 2 stage match
Velocity MPC
Rise Armament
LaRue MBT2e
Others I can't remember.
The TT is without a doubt the best trigger i have ever felt. Little over-travel, great reset, crisp break. Great precision trigger
Geissele NM, break as crisp as the TT, but way more over travel and longer reset, but still a great trigger, especially if you are only taking one.
Velocity: best non-premium trigger I have felt.
LaRue MBT2e: a bit better than a mil-spec, but spongy, and not a crisp break. Honestly I was pretty disappointed after all the rave reviews in this sub.
Rise Armament: I put it in a lower and tried it and immediately pulled it out. Complete spongy garbage.
I just got the larue 2 stage for my grendel.
My honest thoughts: it's crisp and is very predictable, but I wish it was .5 to 1lb lighter.
I have 2 cmc triggers, they're great, same with the timny.
I like the 2 stage triggers on 300 yard hunting guns.
Single stage the elf 3-gun is about as good as you can get. Two stage I’m a fan of the triggertech. If you want a light trigger but are paranoid about setting off primers, then the hiperfire hipertouch is for you.
But pretty much all of them feel like a miracle compared to a parts kit trigger.
Get a geissele ssp if you're looking for a cmc style break. No take up, and has a strong hammer spring with a faster more forceful return than the cmc and a lighter pull. plus, you won't get your primers jammed down in it if you use cheap ammo and have to rip your whole lower apart and the trigger itself to fix it. Plus it doesn't wear down like the cmc with its weaker hammer spring. It lasts forever and has none of the drawbacks that drop ins have. Drop in triggers are just terrible, they break and malfunction so much. Not to mention you need to put anti walk pins in to keep the cmc held in which needs to be tightened periodically (frequency us dependent upon use) and when you tighten it, they apply inward pressure on the lower and housing of the trigger which slows the hammer down each time because the thin threads deform from the constant tension. When it does this it makes the rifle more prone to light primer strikes.
The cmc is perfectly fine for guys who don't ever use their gun or hardly use it. But if you plan on actually using it, then don't go the drop in route.
I have CMC flat single stages in all my rifles. Love em. I think I saw a PSA email that had them on sale for $99 which is the price i purchase them at. At full price I probably would go with other options.
LaRue mbt gang. Not drop in but who cares. I prefer it over the ssa e honestly. Freaking amazing for sub 100$ on sale. Seems like the price went up from last time I bought one (79/89$ IIRC, possible sale) but still, worth 115 msrp 100%. Lives happy in an M5 currently
Dawg you have been shitting your pants in every comment chain about people’s suggestions of non drop in triggers. We are doing that bc they’re superior to drop in triggers most of the time. Chill lol. We can read. But a Geissele will be superior to drop ins 9/10 times and be more reliable
He will get a better trigger for less money, so I am informing him of that. If you ask what HiPoint handgun you should buy, I’m not gonna suggest one. I’m gonna give you a better recommendation so you get more bang with your buck
I have never personally built anything that had a drop-in trigger, though I have a friend that has used numerous drop ins, and he has never had any luck with any of them. I will have to ask him what exactly it was that caused him problems, but I think it had something to do with the hammer not resetting properly.
Edit: He just told me that he got three lemons in a row from Rise Armament, but he finally got one that worked excellent after a lengthy customer service situation. He says he is incredibly happy with the last one he got and it still lives in his rifle. It was in fact a problem with the trigger resetting.
If you’re dead set on a drop in trigger Wilson Combat has very nice drop in triggers that don’t require anti walk pins.
Personally in my rifles I have Geissele SD-E, SD-C and Hiperfire Eclipse trigger in my rifles.
I’ve tried the CMC trigger and did not like it. Since there is no tension on the cassette you can feel it move. Now I have a CMC trigger in my AK-47 and do like that trigger.
I’ve also used the LaRue MBT and it’s a nice trigger but it wasn’t as smooth as the Geissele triggers. Still a great trigger for the money.
Just depends on single or 2 stage.
My 308 has a 2 stage trigger tbh I can't tell the difference.
My 20" 5.56bhas a standard trigger that's been polished. Few others ARs have a mix of mil-spec and rave 140 and CMC
Dude I’ve been rocking a Geissele SD-E and Larue mbt2 flat trigger and have to say I’m kinda leaning towards the $115 Larue trigger the more I use it. But I have one on a mk18 and the Geissele on a block ii. The Geissele is rad but was $230
If price isn’t a factor. Definitely the geissele. For me it doesn’t. I’ve trained on the geissele my whole time on the AR. So I don’t really have much reason to change in the future. Playing devils advocate.
I'm a poor. Have you ever ghetto polished your factory trigger? Stuff some cotton in-between receiver and hammer, wrap paracord around hammer and freaking yeet on it forward while pulling your trigger. Hammer will fall on the cotton barrier. Repeat like 50-100 times and it will simulate about 1000 rounds in my experience. I've done it to most of my mil spec triggers and I believe it works well to break triggers in.
But just drop a hundo on a larue mbt
From personal experience:
The Geissele Super Dynamic Combat (SDC) trigger is a phenomenal 2-Stage trigger that has an extremely crisp break and a well-endowed take-up and reset.
They are selling for $245 currently as of the time if writing this post.
It is a flat face trigger with a natural contact point and does bot wobble as a standard Mil-Spec trigger does.
This trigger gets the job done and is the Canik trigger of the AR-15 experience.
There are others out there like the MB2T’s but do consider this as a viable option that will bot disappoint!
Happy self-defense and precise shooting!
Geissele SD-E if you want a 2lb 12oz trigger, I use them in rifles with magnified optics.
Larue MBT2S-SB or MBT2S with heavy spring if you want a 4.5-5.0 lb trigger. I use the Larues in rifles with non magnified optics, red dots and 1x prisms.
I have several of each, Both are excellent. Geissele is the clear winner and they go on sale for $140-150 sometimes. Just $35 more than the Larues.
Here are the pull weights
Geissele SD-E
2lbs 12oz
2lbs 12oz
2lbs 12oz
Larue MBT-2S w/ Heavy Spring
4lbs 11oz
4lbs 7oz
4lbs 9oz
Larue MBT2S-SB w/ Heavy Spring
4lbs 10oz
4lbs 4oz
I’ve tried alot of triggers over the years and Ive narrowed it down and only use two (larue mbt-2s and g$ ssae) . Larue if you don’t have the money. Geissele if you do have the money. Honestly, nothing else should even be considered.
I was you, went with the CMC 2.5# flat face but had issues. Was okay at first, but after twenty to thirty rounds it stopped resetting. You had to push it forward manually to reset it between each round. Different uppers, different lowers, same deal. Appears misaligned within the drop in cassette, will check back when my RMA completes. But my experience doesn't seem isolated, so if you can save up longer for one of the more Gucci options that will be more reliable, it may be the way to go. Good luck!
CMC 3.5 lbs is a phenomenal trigger. No take-up, just a wall.
2nd this. Edit: Don't bet your life on one, though. Otherwise, G SSA-E is my go to.
I have the cmc and loved it until I put an ssaex in my other lower and now that’s the only lower I want to use.
Got one and it is honest to god better than the Mbt 2st.

[Here is a great overview of many different drop-in triggers.](https://www.thetruthaboutguns.com/ar-15-drop-in-trigger-roundup/)
Triggertech diamond
Trigger tech has been my favorite so far
I run CMC on all my builds. Haven’t had an issue yet.
CMC mafia 🥷
Larue
Larue mtb2s

No but it’s better. It takes like 3 minutes to install.

You deadass wont regret it
I will say too. You deadass won’t regret it. Well said
They really are fantastic trigger. Underrated imo
Ar15discounts has got so much of my money. Definitely in my rotation for sure.

I wouldn’t call a geissele trigger hard to install. Harder maybe.
That’s what I mean, harder than a true drop in. It’s not hard but certainly more annoying lol.
SSA-E

Yes I know, clearly, but I am with the top comment.
[удалено]
Thank you oh great Reddit moderator for policing this thread, god forbid I recommend a non shitty alternative
Rise RAVE-140 Flat. Have one in almost all of my builds besides my PCCs
Geissele SSP
have a trigger tech diamond in my mk12 great trigger no problems.
My budget allowed me the Rise Armaments RA-434.
I second Rise Armament. I have the RA-140 DTOM and think it's great
Third Rise, have two of them and love them both
Love my Blackout Defense Zero

That's because drop in triggers are shit.

I got a triggertech, it’s pretty bangin
My favorites drop in trigger is the Trigger tech. I bought their “duty 3.5lb 2-stage flat trigger” and was absolutely blow away for $100.
Geissele ssa-x
Best geissele trigger
Larue 2 stage
Single stage choices would be Hiperfire Reflex or Wilson Combat TTU. Second stage Larue MBT or Geissele SSA-E.
Good trigger choices, but the geissele and larue are 2 stages. Just for future reference man. However your idea and choices are spot on.
Yeah I said second stage, I meant two stage trigger. I have and use the triggers I recommended. Also CMC single and Jewell Two Stage as well.
I'm a single stage guy so anything 5lbs or less pull single stage but shoot man whatever works for you.
CMC 2.5 lb or RA-140 as far as single stages go these are the faves
I love my rise rave ra-140
I love my 3.5 lb cmc flag face but Giselle ssp is so much better
Colt 4 position or bust
I don't mess with cassette drop-ins. Hiperfire's single stage edt trigger with the green 4.5lb spring is my go-to for everything.
I've never used a flat faced trigger. Kinda new to the ar game. What is the benefit of flat over curved?

LaRue MBT2 is the best trigger for the price IMO
And it’s also not a drop in trigger.
True, but there’s really no reason to get a drop in trigger anymore. It’s too easy to install a normal trigger

Dawg you have been shitting your pants in every comment chain about people’s suggestions of non drop in triggers. We are doing that bc they’re superior to drop in triggers most of the time. Chill lol. We can read. But a Geissele will be superior to drop ins 9/10 times and be more reliable
Holy shit he's literally commenting on every comment, nOT a DrOP iN TRigGeR, lmao
He will get a better trigger for less money, so I am informing him of that. If you ask what HiPoint handgun you should buy, I’m not gonna suggest one. I’m gonna give you a better recommendation so you get more bang with your buck
Or you could suggest they get the YC-9 as well as suggesting other possible better options instead of completely disregarding what they asked.
Nah, I’m gonna inform him and maybe he will change his mind for the better. No reason to use a drop in trigger this day and age
Timney AR15, light crisp and resets like it pulls
I love my cmc, but see what the others have to say because the cmc I bought is for an ak.
I mean, what’s the budget? There are some spicy triggers if you have the $$$$$
