80 Percent Lower Completed Using Drill Press and Mini-Mill with Modulus Arms Universal AR-15 Jig

Posted by

The Modulus Arms MAJ-15 Universal AR-15 80% Lower Receiver Jig was designed to be the easiest and most accurate Universal Jig on the market, requiring only a handheld drill and a common router to finish an AR-15 80% lower with absolute precision.

To further highlight our Jig's versatility, a member of the AR15.com forum recently completed his Modulus Arms 6061 T6 Billet lower, making use of a drill press and mini mill. This individual is fortunate to have access to high quality machining tools, which undoubtedly makes the 80% lower finishing process even more simple.

Our comprehensive instructions and feature manuals outline a step by step process for completing a lower using a readily accessible handheld drill and variable speed router.

We'd like to share this customer's very thorough and detailed account of how he utilized our Universal AR-15 80% Lower Jig to finish his lower using a drill press and mini mill, for our customers who may be considering the same method.
