The Easy Jig® + (1) .308 80% Lower kit from Polymer80USA presents the world’s easiest-to-use, fully universal 80% lower jig designed specifically for finishing DPMS Gen 1 pattern .308/AR-10 lower receivers. This product combines the patented Easy Jig® Gen 3 milling system with one high-grade polymer 80% lower blank. It offers unparalleled precision, durability, and user-friendliness for home fabricators seeking to build their own lightweight, high-performance .308 lowers quickly and accurately.

• Jig Construction: Reinforced polymer jig body with patented Trident front mounting pins to eliminate any movement—yaw, pitch, or roll—during milling for perfect alignment.

• Lower Material: Glass-reinforced nylon polymer designed for extreme durability, corrosion resistance, and weight under 8 ounces.

• Included Components: One 80% polymer .308 lower blank, Easy Jig® Gen 3 system, solid carbide 1/4″ end mill, drill bits (5/32”, 19/64”, 3/8”), custom tool wrenches, and comprehensive instructions.

• Estimated Build Time: 60 to 90 minutes using a fixed router, drill, and vise.

• Features of Lower: Reinforced buffer tube ring, integrated trigger guard, ergonomically flared magwell for faster reloads, no-thread pistol grip mount for modularity.

• Warranty: Lifetime warranty against manufacturing defects on the jig and polymer lower.

Usage Overview:

The Easy Jig® securely holds the blank lower while guiding the user through the exact routing and drilling steps required to finish the receiver. Milling is done in three progressive passes with the included carbide end mill, each pass guided by different height pillars on the jig. Drill holes are precisely located with pre-set holes in the jig that accommodate the supply drill bits. Extensive tutorials from Polymer80USA cover tool recommendations, safe milling practices, and troubleshooting.
