ARIZONA REGULATOR ® Proving Grounds running new AZR Model Engineered for SIG MPX

Jun 3rd 2026

Yes you read that correctly. 

Had a friend of mine a while back ask me to create a 3 position S.F.T. engineered for his SIG MPX.

So I went ahead and created a new AZR Model Engineered for use in a non Mil-Spec Pattern Gun.

The SIG MPX.  Why is it a non Mil-Spec Pattern gun?

Because the internals are different than a standard Mil-Spec AR.

The SIG MPX works perfectly as SIG engineered it to do. It just has some different internals that are not the same as the Colt Prints I engineered the original AZR Line for, or DDM4 Std Mil-Spec AR we use at AZR. 

Back from ripping 1500 rounds downrange and works like a charm. 

Once we get another 3500 rounds thru it for a total of 5000 rounds downrange, I'll start running these across the equipment for for yall to order from us or buy at one of the ARIZONA REGULATOR Dealers.

Won't take long

THUS DO NOT USE THE OTHER MODELS WE MANUFACTURE IN THIS SPECIAL PLATFORM GUN.

ONLY THE NEW MODEL WE ARE SHOOTING AT THIS TIME WILL BE FOR USE WITH SIG MPX.
