Hi Everyone,

We are very excited and proud to finally roll out the Addax GPU's (Gas Piston Upper) for the AR15 Rifle.

The design of the Gas Piston System is based on the AK, and the OEM PWS manufacturers these systems for us.

The Addax GPU is not just for those who are full auto shooters, or for Law Enforcement and Military.

The Addax GPU is and Excellent Option for all AR15 owners who want a Cleaner, Easier to Maintain and Reliable AR15 Upper Assembly while retaining AR Accuracy, all in one system.

AK Reliability, AR Accuracy, that is what we know our GPU's are capable of.

We are only using quality components and barrels in our builds, and we have shot our Addax GPU's allot, in full auto, semi auto, dirt testing, etc.

PWS the OEM of the system has worked with us extensively in our GPU product development and testing.

Look for some reviews / articles coming out very soon about the Addax GPU's, and we will be advertising in Shot Gun News, and we will have tables at the SAR Show and possibly the SHOT Show.

We have several upper models available for sale currently on our website and we will be introducing a few more very soon.


We also offer Addax GPU retrofits for many different types of AR Uppers.


Here are some pics of the different configuration Addax GPU's we have built for customers (Law Enforcement, Military and Civilian), and for our product development and testing.

We offer Law Enforcement, Military and Dealer Discounts.

Some Very Short Videos of our Full Auto testing we conducted with PWS in Idaho recently.

We will have more clips soon.

In this video, you will see me shooting our Addax Carbine A3 GPU in full auto. The buffer is a standard weight buffer using a standard spring, and I am shooting PMC .223 55 grain.


This is another short video clip from 2 different videos, showing an Addax Combat Carbine Gas Piston Upper prototype I am shooting, set up with a heavy buffer and heavy spring, using the same PMC .223 ammo.
