Hey Fellas, just ordered one of these after falling in love with a flat trigger on my Glock30 (no flames please  ). The reviews were great all over the 'net and I figured I'd share.

I'd love to hear opinions on the trigger if anyone in the horde has used one.
I'll post up a quickie review after I check it out.

My buddy just got his this weekend, from the same email. He put it in his milspec 5.56 bushmaster and was blown away. I on the other hand was left with some rather lackluster trepedation over it; nice trigger I guess, but it didn't blow me away... perhaps it was the flat face. I told him to wait a few mins and I came home to get my MBT - 125 bucks regular price with a rather short wait. LSS - After a half dozen dry fires on the Larue, He is sending his 99 POF trigger back to PA in favor of his own Larue MBT 2s. I think he is wise. For the money, I don't believe you can beat the Larue MBT. I never said a word other than "Here, try this."
My impression of the POF was that it was a nice single stage, repeatable breaking trigger, and was a decent buy at $99. We did not shoot it, only did some dry fire break drills. If you like flat triggers, it will probably fill the bill rather well. I do personally recommend the Larue though, unapologetically.

I've hear lots of good things about the LaRue MBT2S. I'll have to try one out on my next build. I just got the POF and I like it but have not had the chance to live fire it.
So far I like the lack of pre-travel and the break is glass-rod-esque with practically no over-travel. Pretty good in my book. The LaRue must be spectacular if the POF is an instant no-go.
Thanks for the input!

Don't misunderstand! The POF was great, but I don't think he realized it was a single stage, which probably had more to do with why he returned it. If you like no pre-travel, the MBT is definately a two stage.
Single stages take some getting used to. Personally I like having the "set" stage before the break, but like I said above the POF was predictable, crisp, and repeatable. Good stuff.
Need a range report!

That's interesting, because single stage is the natural and intuitive one for me, and dual stage takes some practice/adjustment.

When I shot M1 Garands and Mausers (2 stage) for the first time after American hunting rifles (single stage), it took me some time to get used to it.

I'm thinking precision shooting I guess, I want the take-up first stage. For blasting, speed gunning, etc. the single stage is great. I broke my MBT by accident several times when I first started pulling it, so I guess you could say I had to get used to it as well. For bench rest or prone though, where Grendel really shines IMO - 2 stage is the way to go. OP asked for my opinion, that's what he got!

LOL, humans are funny. I think the two-stage is fine for blasting because you never notice it, but not good for precision. My Grendel for hunting has a Timney single-stage 4#.

Heh, we be two sides of the same coin.
Do you like the set triggers? How about accu-triggers on bolt guns?

I'm not familiar with either of those terms. The Timney is my first really great trigger. Before that I've had jobs done or used some mid-level upgrades, but nothing that good. Until only a few years ago I was primarily a handgun guy.

I like the flat trigger. You can reduce the pull weight due to leverage by contacting the trigger near the end.
If you do this on a curved trigger your finger is on a pointed end and is uncomfortable.

Accutrigger
http://cz-usa.com/news/the-cz-single-set...er-system/
Set trigger
There are lots of examples of attempts to produce the extreme-light trigger break of an extremely shallow sear engagement, these two are just examples. I'm not sure how Timney first produced the light single stages with a degree of reliable safety, but the results are all over the AR world, and Timney is one standard by which most other single stages are measured.
The MBT works in my mind very similarly to the Accutrigger originally from Savage; There is a first stage that has a slight take up allowing the shooter to bring the trigger to the break with a definite stop in travel, then a slightly heavier pull "breaks" the sear and fires the weapon. In my mind, this works well because I know that once the first stage has been pulled, the break is next. I can pull just to the break point, stop, posture/breathe/final aim/hold - break. The single stage is like this, but there is nothing but a break. So, you have to introduce your input to the weapon via trigger ONLY when all the other factors are already done. Just a difference of practice I assume. I would be interested to hear your opinion of a really good two stage in precision shooting.

With a single stage trigger keep your finger off the trigger until ready to shoot.
Placing your finger on the trigger is the first stage. It is a light touch. Then squeeze for the second stage.
A 2 stage trigger is safer if dropped. That is why it is used on older military rifles. I don't know why it was abandoned on the M16.

One of the reasons I purchased the POF is the fact that I don't have a single-stage trigger and it is my first drop-in as well. My grendel has a LMT lower that has the 2-stage "match" trigger that I like but it is probably in the 5#+ range. All my other ARs have creepy mil-spec units of varying quality.
Ultimately, it's just another range-toy to try out! One of these days I'll get back to high-power metallic silhouettes...prolly after my kids are all off to college and beyond.

I'm getting excited to hear how YOU like the POF. Send some and write it up.

Well, here's my dry-fire review...tl:dr...Really like it.
When you first place your finger on the trigger, there is no movement, none. I believe this is due, in part, to the urethane feet on the bottom of the unit (two urethane cylinders which run the width of the cassette which can easily be removed). These get compressed as the pins are inserted to eliminate any vertical play. There is no lateral play either. The two aluminum sleeves through which the pins are inserted are a fairly tight fit within the lower. If the sleeves are not centered in the cassette, the cassette will not drop into my PSA lower. Since tolerances vary, so will your mileage.
There's enough weight to the trigger, to my hand, to preclude a ND unless you're not in a static shooting position (why would you have your finger on the trigger if you're not ready to shoot anyhow?). There is also no movement, AT ALL, as you increase tension. When it breaks, you feel no grit and travel is minimal. Reset is not the smoothest affair, certainly not as crisp and light as a glock trigger. You can feel metal dragging against metal here and this creates the sensation of a reset that is longer than the travel at break.
Well that's it for my initial thoughts. I'll let you know if I can keep the shots on the paper when I get a chance to visit the range.
BTW, I read an excellent review of a bunch of drop-ins at, of all places, TTAG...very thorough:

I have 2 POF triggers in my AR's. One in my 223 Wylde and one in my Grendel. Awesome single stage triggers. Perhaps a little heavy in a target rifle. They break like glass with virtually no creep.

I have the POF 3.5lb straight trigger on my 223 wylde 18" spr . It's the best bang for your buck . Sure ,it's no Timney or Trigger Tech , but considering it comes with the KNS anti-rotation pins it's a great deal on a good trigger . It has no perceived creep to me and breaks like glass and has a very short reset and travel . My only complaint is it doesn't feel like it's 3.5lbs . It feels more like 4lbs to 4.5lbs. I'm glad that triggers are finally becoming more affordable.
