Brownells 75th Anniversary - A Shooting Heritage

Building an AR requires careful component selection. EGW spent most of its time finding the best stock, grip, optics and trigger, but the rest of the lower parts kit always feels like an afterthought. They felt that there was a hole in the market for a US made, machined from solid, high quality, corrosion resistant lower parts kit, so they went to work. The designs have been finalized, materials selected, and coatings tested. EGW is excited to announce, their EVOLVED AR Lower Parts.

When you are the manufacturer, not just an assembler, you have full control over how your products are designed, manufactured and finished. All of the components (aside from the springs) in this kit are machined in house from 4140 tool steel barstock or 7075 T6 aluminum. After they machine them, they are sent to a local heat treating facility and then sent off for a QPQ coating. All of the springs are stainless steel to help prevent rusting. EGW springs are made from stainless steel to help prevent corrosion. EGW knows you are going to pick out your own trigger, trigger guard and safety selector anyway, so they left them out (for now).
