Thanks, Montrala!

 

Thanks - much appreciated.

I've emailed Geisselle but no reply for over a month

Jp would be easier and their customer service is very good.

Has anyone tried the UHL trigger? I can get that one easily from Germany.

 

UHL works, however it has wery weak hammer spring. It has problem with moderately hard primers, not to mention really hard ones (surplus and Russian ammo).

For time being I recommend either JP or Wilson Combat. I will use CMMG 2-Stage on next 3Gun match (this Sunday) just to see how it works for me, but it is heavier than JP (I use JP with "tactical" hammer spring, for positive ignition) and has longer reset.

They have sent me a new one/stronger one from UHL when I called them and mentioned about some issues with a hard primer ammo.

Here are some pics of my MR223A1 with the UHL trigger:

 

Just FYI,

I had installed a Geissele SSF in one of our dept's Colt M16's some time back when we wanted a "marksman" type rifle in our inventory. I put my 416 upper on it for grins. I was getting very light primer hits with failures to fire about every 5th or 6th round. I tried my other 416 upper with this lower and was unable to get any rounds to fire as there was very light dimpling on the primer. Thus, I would not rate the stock SSF as a reliable option for the 416.

 

Updated. However listed were only special SSA version (that Geisselle offers for almost $400).

 

Funny thing, I just heard about another trigger maker, that does not have HK compatible trigger with exactly same story, that I heard before: "Yes, we made batch of our triggers in HK version on special order for SOF unit, but we do not offer them".

 

I have emailed Geisselle about a month ago about triggers to MR223, but no reply and I don't think I'll get one either.

According to rumors, they make triggers for SOF units as well

 

Updated:

ALG Defense ACT
ATC AR-Gold Trigger (needs fitting for MR223 due to rear receiver pin location)

 

I assume the ALG QMS is a no-go?

 

Anybody have any experience with any of the Wilson triggers?

 

If you call them you will get Bill himself, I have called several times and he either answered the phone, or called me right back. Basically he started making them for SOF and I do not think he was ready for the explosion of civilian orders and SOF/DMR considering he answers phone himself. He probably never gets to his computer, but his triggers are A1...Just my .02

 

Any confirmation of the Timney trigger being compatible?

 

I have the Timney skeletonized trigger single stage 3 or 4 pounds (don't remember which one I ordered) I have never had any problems regarding the firing pin safety. The only problem I had was soft primer strikes with some xm193. I contacted Timney and they said that they could fix it. I mailed him the trigger on a Monday and he sent me a brand new trigger by Friday with a stronger spring. Haven't had a light primer strike since then. I love the customer service with them.

 

KAC two stage works.

 

Updated: KAC 2-stage.

Thank you.

 

Will the KAC 2-Stage full auto work on a 416 lower?

 

Seriously there is not any sense in using one in FA gun! Get the Geissele full auto trigger for the 416. 3-5K rounds will rack up in little time out of a FA rifle. Spend a few more bucks and be done. IF it was a KAC full auto rifle I could see wanting to use their trigger but since its not there is virtually no use.

 

I can get a kac fa 2 stage but not the geissele 416 ssf. Would have preferred the geissele though.

 

Go with the KAC then. Just be prepaired to change out the trigger every 3k miles I mean rounds.

 

That sucks if thats the case I'll hold out till I can get a geissele. Thanks for the heads up!

 

Yea it does suck.

The only reason i'm running the KAC two stage is because I already had it from another project, and because I had it nitrided so i'm hoping that it lasts longer then the normally do.

If it turns out that they are really that crappy and even nitriding can't make them hold up much longer then they already do, I'm never getting another KAC trigger ever again. Screw that noise.

 

The Chip McCormick drop in single stage match trigger does NOT work. We are keeping track of the ones that don't work, right?

 

I have a Timney 3# in a POF lower that hasn't had any problems firing a 416 upper. Its seen less than 500 rounds though. School might be out on it, but I like it.

 

Which is the best trigger on the list ?

The only one I have seen in person was the wilson combat, it was awesome. Any thoughts on the wilson ?

 

That's awfully loaded and subjective especially without an intended purpose? Does "best" mean:

Lightest pull?
Cleanest break?
Most reliable?
Longest lasting?
Best value?

 

I just ran near 6000 through with the ALG ACT. It's not a match but hands down the best combat trigger. Still feels like new, if not, a tad, tad lighter. But maybe I'm just used to it.

I just through on the Geissle 416 SSA with a Surefire MB and what a combo. My RDS hardly moves off target.

Considering they're only $65, the ACT is one of the better things going at this time. I can't say enough good things about mine. My only regret is not buying another to have on hand.

 

As far as the Wilson Combat TTU 3G goes, I love mine. Consistently crisp and light break without any creep. Installation was a breeze.

 

I am considering the Wilson TTU 3G as well. After you had been using it, any issues at all on this trigger?

 

KAC 2 stage and Geissele SSA

Having both KAC 2 stage and Geissele SSA I like both but the Geissele is much better-lighter and crisper.

 

I too, swapped in a Timney. I'll update as I go.

 

Wilson TTU DOES NOT WORK with the MR556A1. Failure to fire on every round due to weak, unchangable hammer spring resulting in light primer strikes.

 

Now now before you flat out say it does not work I'd at least give Wilson Combat a chance to fix the issue with you. My TTU 3G works fine. I am curious as to why yours isn't working so well.

 

I wonder if the hammer geometries are different between their TTU and 3G TTU. The 3G I have works without a single hitch.

 

I did ask Wilson this exact question. They said the hammers are exactly the same.

 

TTU remarks reflected in first post.

 

I know this has been mentioned, but I thought I'd confirm my experience. The JP Enterprises EZ Trigger works with my 416 upper with the firing pin safety intact.

 

What color hammer spring are you using to make it work? Yellow or red?
