Welcome to another Tactical Tuesday! Once again, it’s the very special day of the week when Guns & Tactics dedicates a blog post to one of our many favorite firearm builds. This ain’t no ordinary gun gallery, these precious blasters are amazing works of art.
The Rainier Arms billet uppers are CNC machined from solid billet 7075-T6 aluminum, which is 70% stronger than the commonly used 6061 aluminum, and they’re finished with milspec hardcoat anodize to a surface hardness of 60 Rockwell. Best of all, these babies feed GLOCK® 9mm magazines. Total awesomeness!
Check out our previous Tactical Tuesday posts for your inspiration for your next build.
