We started out as an idea in a Houston area garage after asking a simple question…. How would I do this and long story short the Gas Block Roll Pin Fixture or as we call it the "Widget" was born. This is our flagship product and while it is the backbone of SMA, we are not resting on this tool alone. We are working hard to find new and better way of doing things, and bringing you the best of what is already out. When you hold a SMA tool in your hand you should feel the quality, and know that it was made in the USA, by American workers, and in a very real way your purchase helped put dinner on the table for a family, or maybe even a worm on a hook on a family fishing trip. This is what we strive for everyday not only to get the good honest gun builders of our country the best tools we can but also to take care of our fellow Americans because at the end of the day our best way to help ourselves is to help each other. While SMA is a veteran owned and operated business, what we really strive for is the tools, parts and gear should speak for themselves. We want the merit of our tools and gear to be what brings you back the next time you need a new tool that’ll last a life time. The widget design has been optimized into 1 tool which accommodates all 4 sized of AR gas blocks, The GBT-4. We still have all the earlier version of our Gas Block Tools and a broad assortment of AR-15 parts.
