Reasons Our 80% Lower Tool

Kits are the best

We’ve been building tools right here in the U.S. for over 40 years. Most companies compromise the quality of the end mill and drill bits with low quality, overseas sourced parts. We take great pride in delivering the best product you can get on the market.

40 Years Reputation

We’ve been making cutting tools for 40 years and make the best tools you can buy.

Last 4X Longer

We deliver drill bits and end mills that are the most durable you can find on the market.

Made and Used by Pros

Veteran owned and operated, we understand that the quality of your firearm is critical.

R&B Tactical Tooling


I’ve been looking for the best tools I could find on the market to drill my 80% lower receiver and I’ve finally found it! These drill so much faster and more reliable than the other options I’ve tried.
