The Modulus Arms Router – Key Takeaways

One Jig for Everyone!
We’re huge fans of the Router Jig Extreme’s universal compatibility. It seems the company stands behind the commitment of making one jig for everyone. We wager that they’ll continue to update and offer new parts for the Router Jig Extreme as new lowers are developed – and in the meantime, this jig is perfect if you plan on building every type of AR available!
The Patented ReadyMill System
The Modulus Arms Router Jig Extreme’s so quick because of its ReadyMill System. This system uses a heat-fit (otherwise known as shrink-fit) end mill holder. This provides increased rigidity and stability while machining, guaranteeing a more precise cut and cleaner look once finished.
The ReadyMill System is not a gimmick, either. Modulus Arms took a lot of time designing the ReadyMill system for the most popular handheld routers on the market. They boast four versions of the ReadyMill, spanning a selection of the 18 most popular routers, likely including yours!
Stylish, Rugged, and Easy to Use
Modulus Arms throws in some very good instructions and tutorials with their jig, providing first-timers the confidence to build at home with no troubles. We’re fans of the Router Jig Extreme’s anodized red finish and its shop vac attachment. Keeping shavings and waste free from the cutting area is critical in making a reliable, precise lower.
Lastly, we like the size and weight of the Modulus Arms Router Jig Extreme. Your jig should remain stable and rock-solid while you work, and the Router Jig Extreme’s built-in guides and hardened, larger side plates provide plenty of stability while working. Overall, the Modulus Arms Router Jig Extreme appears to be a great contender for best router available – you can check it out and buy it here!
