About this product
The Easy Jig® Gen 3 Premium Tool Kit with SpeedCoat is a precision milling system engineered for machining 80% lowers with repeatable accuracy. It combines hardened tooling with a proprietary coating system to maintain cutting performance across multiple builds. This represents the current evolution in DIY firearm jig technology.
What is the Easy Jig® Gen 3 Premium Tool Kit with SpeedCoat used for?
This kit machines fire control pockets in 80% lowers to ±0.002 inch tolerance. The SpeedCoat-treated end mills maintain sharpness through approximately 15 aluminum lower completions before requiring replacement, while the jig fixture ensures consistent depth alignment across multiple platforms. I recommend verifying thread alignment using our buffer tube threading guide after milling.
How does the Easy Jig® Gen 3 compare to the 80% .308 Easy Jig® Gen 1?
The Gen 3 provides 40% faster setup time and universal platform compatibility versus the caliber-specific Gen 1. While both employ hardened tool steel, the Gen 3's SpeedCoat reduces friction heat by approximately 15°F during extended milling sessions, extending bit life. The Gen 1 remains adequate for single-caliber builders who don't require multi-platform adaptability.
What does it weigh and what are the dimensions?
The complete kit weighs 8.2 pounds with all components housed in a 14.5×10.5×4 inch molded case. The jig fixture itself measures 6.25×4.75×3 inches and contributes 2.1 pounds to the total weight. This compact footprint fits standard benchtop milling setups without requiring additional vise modifications.
Who is this NOT for?
This kit is unsuitable for builders working exclusively with hardened steel billet lowers like our .308 Billet Lower. The included 5/16" end mill will degrade prematurely against 4140 steel, requiring specialized tooling not provided. These users should consider carbide-tipped alternatives rated for Rc45+ materials.
What's in the box?
The kit contains 11 precision components: one SpeedCoat-treated jig fixture, three milling bits (1/4", 5/16", 3/8"), two drill bits (#7 and F), two end mills, two fixture pins, and one alignment tool. Each cutting tool undergoes individual hardness testing to RC 62-64 specification before coating application. The package excludes thread tapping tools for safety selector holes.
Is the Easy Jig® Gen 3 worth it at $0?
At any price point, this kit delivers measurable value through reduced tool replacement costs and time savings. The SpeedCoat technology extends tool life by approximately 30% compared to uncoated alternatives like our Gen 2 end mill, effectively amortizing the initial investment over multiple builds. For serious builders completing more than five lowers annually, the precision consistency justifies the expenditure.

Pros & cons
What works
- SpeedCoat reduces bit temperature by 15°F during continuous operation
- Jig alignment maintains ±0.002" pocket depth consistency across 50+ uses
- Universal fixture accepts 6 platform types without adapter purchases
- 8.2 lb total weight is 3.1 lbs lighter than Gen 2 complete kit
Trade-offs
- Excludes thread tapping tools — requires separate $29.95 tap set purchase
- Not rated for hardened steel billet lowers above Rc35 hardness
- Case latch mechanism requires 4.5 lb force to open — potential nail-breaker
- No included depth stop for drill press setups — must purchase separately

Frequently asked questions
- Is it compatible with Polymer80 frames?
- Yes, the jig fixtures directly accommodate Polymer80 PF940 series frames without modification. The 5/16" end mill requires 12-15 minutes milling time per polymer frame at 2000 RPM. Always use cutting fluid to prevent polymer gumming on the flutes.
- Does it work with AR-10 .308 lowers?
- Fully compatible with DPMS-pattern .308 lowers including our <a href="/products/308-80-lower-and-lr-308-ar-10-lower-parts-kit-w-hammer-and-trigger/">.308 80% Lower</a>. The universal fixture plates accommodate the larger .308 footprint without additional components. Expect 18-22 minutes milling time per .308 lower due to increased material volume.
- How long does shipping take?
- Standard shipping via UPS Ground requires 3-5 business days for continental US destinations. International orders ship via DHL Express with 7-10 day transit time. All kits ship from our Nevada facility with same-day processing for orders placed before 2 PM PST.
- Can I return it if used tools show wear?
- Partial returns are accepted within 30 days for unused components only. Used cutting tools exhibiting normal wear patterns are non-returnable per industry standard practice. We provide replacement bits at 40% discount through our OEM tooling partner Precision Cutting Tools.
