TriggerTech 2-Stage Trigger - I'm stoked!

- Start date
Oh well, we're getting into the end of the season now, as long as their out and readily available by the first of the year I'm good. That would give me time to work with it before spring. Besides I just lost my job and can't afford one now.
Exactly... I don't know how the TT would possibly be better than the Bix 2-stage. TT does have sweet hats and patches though!
The fact that the 2 stage TT doesn't (to my knowledge) have any way to adjust the sear engagement makes the BnA the obvious choice for triggers and a superior design, IMO.
I'm good with the Geissele two stage for now. It was available when trigger tech wasn't.
As the OP I think maybe you all should open your own thread where you can then make definitive statements about a product that hasn't even been released yet. Fandom is a good thing but it can be carried a bit too far, I'm going to wait with my criticism at least until I have been able to get my hands on the released product.
No fanboi'ism here.
I simply want TT to incorporate a certain important feature, otherwise I personally don't think it's even worth considering.
TT would be completely remiss to not incorporate adjustable sear engagement into their design.

I recently heard of their 2 stage coming out soon. I have their single stage Diamond and like it but it took a awhile for me to get used to only one stage. I'm really wanting to get their 2 stage when it becomes available. I did like my buddies B&A 2 stage and almost bought one a few months ago after talking with him, I'm glad I didn't though.
Like I said I'll reserve criticism until after release and I've had a chance to actually get my hands on one but feel free to speculate in detail.
I have the B&A Tac Sport pro single stage and the TT Diamond single stage, I prefer the TT.
I don't know jack about triggers or how they work on the inside. So, let me ask some questions. What does a sear engagement adjustment do? Is this different from adjusting the trigger pull? On a B&A, are the stage pull weights user adjustable? One of the things I have heard about the TTs is that they are very easy to adjust on the rifle, without removing the trigger.
I could totally be wrong here, but I believe: B&A offers different top sears that engage the cocking piece of the bolt, so you can get the correct one for the action you are using to prevent too much contact and too little contact. They also have an adjustment for sear engagement in the trigger which is basically how much overlap the two pieces of metal have before they break free from each-other.
Almost every aspect of the Bix 2-stage is user adjustable.. 1st stage travel, 1st stage pull weight, 2nd stage pull weight and over-travel as well as sear engagement. With that said, it's still important to have the correct top sear to start with. Top seat is the only thing that requires disassembly, but once correct doesn't need messing with.
The B&A is externally adjustable just like the TT.
So the sear is what catches the firing pin and holds it back against the springs forward pressure until you actually pull the trigger to release it.
I drew a little red arrow to where that interaction takes place. The rest of the trigger design will be different depending on he exact trigger but they all catch the firing pin and hold it backwards.
If the sear (actually top sear)is too high in regards to the firing pin that can cause the firing pin to drag over it instead of being cleanly released and this robs ignition power and consistency.
Too little engagement and it wont hold properly and the firing pin can just ride freely over top.
Ideally it is positioned high enough to catch the firing pin but not so high that it interferes.
So with something like a bix and andy you can actually control the height of that top sear with replaceable pieces that are different heights, 3.6, 3.8 & 4 mm tall. This allows you to control the pieces actual physically dimension, you can still control how much overlap there are between the two pieces by adjusting the sear the replaceable parts just are a little more customizable. Most triggers dont have this set up, traditionally altering the sear geometry meant having to actually get out a stone or file and actually fit the pieces together.
Most triggers that have sear adjustment only allow you to control how much pivot is allowed to the sear which controls the amount of overlap with the firing pin instead of the sears actual geometry. Turning a screw in or out controls how much these two little fine ledges actually overlap. If there isnt enough overlap then the rifle can easily fire accidentally. Too much and it can feel less than ideal for precision, its balancing game.
The interaction between the green and yellow shows that relationship and how they overlap and catch in an ar15 set up
Trigger tech kind of gets over that too much sear feeling by removing the two parallel surfaces dragging along one another and instead introduces the roller to replace dragging friction with friction free rolling while still having adequate sear engagement for safe operating.
Edit: the bix has roller balls as well but it also has some dragging bits. The actual breaking sear surface is down in the lower third and a two surface arrangement, the rest above it is just helping it fall away from the firing pin elegantly.

Guys, thanks so much for all these explanations. Slowly, the curtains are being drawn. It's so easy to get caught up in marketing and hype, when you don't understand what exactly has to happen and how they accomplish that. When you know what happens and what is supposed to happen and why, you can better evaluate somebody's claim about their product. I still don't know enough to say which is better, but I understand more. You guys are great!
Just a random question, does anyone know off the top of their head what seat height I need for a B&A in a BH TL3? I had it written down somewhere and can’t find it.
I beleive its a low 3.6mm, it is according to their old now removed charts and my origin is a low, but you should measure it. Knock the trigger pins in and measure it with your calipers depth gauge. Bolt in and closed put the base of your caliper on the trigger cross pin. Then extend the depth gauge until you hit the cocking piece keeping the calipers 90° perpendicular to the action to measure the distance.
Start at 7 min 42 seconds

No it doesnt. Its a Low 3.6 sear according to that chart you have, you just didnt include the rest of it that actually matters for sear selection. The measurement you get from the action (3.89 for a bighorn here) is not the same thing as the sears label.
<-- TT fanboy here. 2 of these in PVD flat would sure make a good christmas present to myself if they can make it this year.
I know, I’m still waiting too. Is there still preorder open anywhere?
Anyone who has tried out the 2 stage TT, what is the 1st stage travel distance? I played with a Cadex 2 stage and the first stage felt a mile long before hitting the wall of the 2nd stage.
Anyone know if that 1st stage travel will be adjustable or just weight?

Weird because I tried one a couple of weeks ago on a friends rifle in the U.K and i can assure you we usually get everything at least a year after you guys ? It was really nice, better than my TT diamond and the first stage take-up felt just right. No after travel. Exactly as I would want it to be. I will definitely be getting one.
What those will be like when they go on sale remains to be seen, personally my enthusiasm has gone from sizzle to fizzle due to their lack of coherence between marketing skills and ability to deliver a product without teeing off the customer. Announcing a product at SHOT Show for the quarter following SHOT and then not having them out by the time the next SHOT rolls around, not even having a tentative statement on when they might hit the market on their web site is just bad business practice at this point; especially with all these rumors of sightings, and trial runs flying around.
I love their products but this has been tremendously counter productive to their initial marketing. A few of my friends who swear by 2-stage and were waiting by now have gone with Bix'n Andy, if I wouldn't have had a bad experience with them in the past I might have gone that route myself. I just did not care for the feel of the Bix, so I got a single stage TT instead, but I'm a bit disappointed to say the least.

I also got tired of waiting for a TT 2 stage. I like the Tubb trigger but I don't want to inlet for one again. I ended up with a Tacsport 2 stage.
I really want to try one, but their sketchy communication got me to go to a B&A. I might try one when they come out, but my B&A works pretty well 
I feel the same, so opted for a TT single stage, otherwise it would be a second year on a build without firing a shot. Give a dog a bone for christ sakes, at least post an update on your website TriggerTech!

I sent Mr. Kim, (Customer Operations Manager,TriggerTech), an email with a link to this thread in regards to the two stage triggers. Hopefully, he'll reply here to quell our concerns.
Happy New Year All!

I doubt a 2 stage TT is going to be any better then a BnA 2 stage Tacsport in form and function anyways.
I didn't think it would take TT this long to come out with their trigger. Good thing there is already really solid 2 stages available on the market.
Here ya go. Almost one year after the thread was started... coming Q1 2020. Lol. I’ll believe it when I see it.
Bix'n Andy isnt a true 2 stage trigger. It appears the TT trigger is. I have a BnA trigger and I like it, but I'll still buy the TT for that reason.
On a BnA the first stage is just take up. All it moves is the trigger shoe attached to a spring until you get to the main sear.
Look at the picture of the TT, the first stage has a sear safety which is a feature of a true 2 stage trigger.

Diggin that "lucky" green color even though you can't really see the trigger when mounted up.
