ar-15 platforms

The "A" does not stand for Assault!

ArmaLite, a division of Fairchild Corporation is the inventor of the  AR platform we use today. There are so many companies that have used this platform to build from that it's impossible to keep track of them. We like to think that it's one of the most simple and reliable rifles on the market, the AR stands for ArmaLite Rifle! Not Assault Rifle....

   80% kits

AR uppers

One of the most critical platforms of any build is the upper receiver assembly, it's usually the make or break of any project. 


SWTA has been one of the leading builders of high  quality upper platforms using only the best from companies like Wilson Combat and Krieger to mention just a few.

Quality and value

Having the right parts on your platform makes a difference!

When we hear companies say things like "a century of collective experience," we all look at each other and laugh....unless you've been in the trenches and had a weapons system could care less how many years experience the guys around the lunch table have, we make sure each and every part we make, sell or test is a 100% functioning spec grade part, not something made in some back lot...our name and your life depends on it!

We won't sell cheap knock-offs or junk from China, everything we  offer is either made at our facility in Arizona or is custom manufactured for us,  our vendors  certify the origin and manufacturing location for each one of our parts....right down to the detents and springs we purchase locally.


When you've been in business as long as we have and faced technology's increasingly rapid developments, you learn a few things. Or, in our case, more than a few. We not only have simple, ready-to-implement solutions for almost every application, we have the parts for them, too. And, if you bring us something new, our staff would love to work with you to find what you're looking for.

Southwest Tactical Arms  will move all 80% kit and jigs including tools to the webstore in May 2017....Look for them there.


The lower receiver is the heart of any weapons platform, it's what makes the difference between living to see another fight or dying with a jammed weapon.


SWTA takes great care to insure that ALL of the parts used in any of our receivers are made in the USA, and we're very proud of that.
