History of the Milazzo-Krieger M-K II

The M-K II was only in production for a short time with production numbering of approximately 3000 units split between the large pin Colt style models and small pin standard models. The M-K II was introduced in the early 1990’s and was quickly adopted by the US Army Marksmanship Unit (USAMU). The M-K II was used with great results at Camp Perry and in inter services matches setting numerous world records. By 1994 it was the only trigger used by the USAMU in the competition M16 rifles. Some of the original M-K II systems are still competing and winning in civilian hands after all this time. Production was completely halted shortly after its introduction in the mid 1990’s.

Reintroduction of the M-K II

On the 25th anniversary of the M-K II system, The Wisconsin Trigger Company is honored to offer this world class match trigger for the AR15 / M16 rifle and pistol family of firearms once again.

Production will be with the original fixtures and test jigs Charlie Milazzo hand crafted in the late 1980’s. The Wisconsin Trigger Company has made a commitment to hold the same tight quality control and the extreme tolerances that made the M-K II the finest two stage match trigger in the world. All of the major components are cast within the same molds at the same foundry as the first units produced.

Lifetime Guarantee

We are backing up our commitment with a transferable lifetime guarantee on all the trigger systems we produce. The original M-K II was so well designed and manufactured with such high standards, we are pleased to offer this same guarantee to any original M-K II trigger system produced prior to us taking over production in 2015. We will be posting more of the rich history of the Milazzo-Krieger M-K II Match trigger System as it is uncovered. If you or some one you know was one of the USAMU or one of the civilian competitors that used the M-K II to set a record, please email The Wisconsin Trigger Company and let us know if your record is still standing.
