If you’ve been shooting Hi-power for the past couple years, you’ve probably heard of the Wisconsin Trigger and wonder what this “new trigger” on the market is. Well the truth of the matter is that it’s not a new trigger. In fact, it’s the original two-stage trigger that many others have copied. Back in the early ‘90’s, if you were a “serious competitor,” you shot a .30 cal bolt gun, M1 Garand, or M-14. The AR platform was around but not like it is today. Two developments helped make the 5.56 caliber competitive by taking advantage of the inherent accuracy found in the AR platform: the introduction of the 80gr SMK and the Milazzo-Krieger, aka M-K, two-stage trigger. The M-K trigger system was the first to introduce the tail found on the hammer and a modified trigger hook that would catch the tail and hold it in place. This system mimics the hooks found in the M1/M-14 hammer and trigger sear. With the addition of an adjustment screw, the end user can adjust the sear engagement of his M-K trigger using only a 5/64” Allen wrench. That may not seem like a big deal today, but it was revolutionary at the time. Other improvements were a set screw on the bottom of the trigger to allow easy access to the disconnector spring that controls the second-stage weight and a disconnector that is pinned in place rather than rotating on the trigger pin like a GI trigger. This pinning of the disconnector changes the geometry and gives the M-K trigger a superior second-stage break. The M-K triggers soon became “The Trigger” to use. The USAMU quickly adopted the new M-K triggers and started winning and setting national records with them. After several years of production, the designer Mr. Milazzo ceased production of his trigger due to the many patent infringements that were taking place at the time.

Over the years, many of the older shooters talked about how nice their original MK triggers were. In 2015, Ron Albenese contacted Mr. Milazzo and offered to purchase the patent and re-introduce the legendary M-K trigger. They struck a deal, and soon the original tooling, fixtures, and castings were in the new Wisconsin Trigger Company building. The original casting molds are used by the aerospace portion of the foundry where the original castings were made. This insures that the new M-K triggers will still have the feel of the original ones and retain the M-K II cast into the side of the trigger. We use the best of the best. All steps are done by specialty houses that only do that one step.  When a step is done the parts come back to us and we QC them. We have about 30 fixtures for measuring and checking every cut and grind on a trigger.  Extremely. tight tolerances are held during the entire machining of the trigger group. This machining, along with a proprietary heat treating process, makes for an exceptionally smooth first-stage take up that only gets better through use. A crisp 2nd stage break is assured by the use of a pinned disconnector. The hammer and trigger pins are oversized and made on state of the art Swiss-style screw machines. Every trigger is hand assembled and tested on a specially made jig for smoothness and safety, so you’re not getting a bunch of random components thrown together in a box. Ron, the owner, does a lot of the testing himself. All M-K triggers have a lifetime warranty that applies to every M-K ever made regardless of who purchased it. It even covers the original ones made in the 90’s.

For any lower receiver other than Colt, you will need to use the small pin model. This is the 0.154” standard pin. If you have a Colt receiver manufactured between 1990 and early 2009 you most likely will have a large pin receiver. This is a 0.170” large pin. Please be sure to check before you order. One of the nice features of the large pin Wisconsin M-K II trigger is you don’t have to remove the sear block in order to install it. Both the M-K II A1 and M-K II A2 are available in large pin.

Another option is known as the Bronze Advantage. This is a bronze insert pressed into the trigger trunion that helps reduce trigger friction on the pin and gives the trigger an operational smoothness that is second to none.

So which trigger is best for you?

We’ll start with the original M-K trigger the M-K II A1. This is the one that started it all. It comes with a long reset disconnector that is preferred by some shooters and is available in both large and small pin models. You will need to grind the back of the trigger for your overtravel preference.

Next is the M-K II A2. This one comes with a factory preset overtravel. It features a short reset disconnector that is nice for rapid fire stages. It is favored by a lot of shooters and also comes in both large and small pin models.

Next in the line up is the M-K II A3. This trigger is for competitors who want the option to set the overtravel to their preference, but also to change or tweak it at a later time. The overtravel adjustment is found in the selector switch and can be installed for either right or left hand use. It also has the short reset disconnector. It is only available in small pin.

The newest offering is the M-K X trigger. This trigger is manufactured with National Match shooting; Long Range competition and precision marksmanship in mind. The M-K X features the best of the best with: A3 tail; Wisconsin Trigger safety selector for adjustable overtravel; the Bronze Advantage and a new purpose designed X disconnector for National Match and precision shooting that features a long reset and has the finest release found on the market.

I followed a link to this page just for pictures.  Leaving most disappoint.

Unable to get a response from The Wisconsin Trigger Company by phoning them, emailing them, and writing an actual letter, putting a stamp on it, and putting it in the mail. Their phone inbox is full. All this after waiting over three months on an order placed online.

All items mostly out of stock. I'm not sure if their still in business, buyer beware.

Unfortunately, Ron Albanese, the owner of the Wisconsin Trigger Company, passed away in July last year (see page 6). At the time I believe the company's Facebook page said it was going to 'reorganize' but their webpage now gives an 'expired certificate' security error; it's probably safe to treat the company as 'gone'.

Acetomco, I hope you can get your money back if they billed you; by the timeline it looks like you placed your order shortly after Mr. Albanese's passing, and everything would have been in chaos.

I just checked and their website isn't working. 503 error.

On a side note, I grew up in Watertown, and Mr. Albanese was my high school auto shop teacher. Had no idea he was into high power shooting or guns at all. By the time I found out he owned this company he had already passed.Small world.
It's sad his company seems to be failing.

Also looked at the companies location on google, right next door to where my dad used to work. Real small world.

I was billed. I will never get a refund or the product.

They're back.  They apparently were in the building with Fulton Armory on commercial row at Camp Perry for the national matches.  I was in there, but just looked at some Garand odds and ends, and didn't pay attention to anything else.
