This Elite Builder 80% Lower Jig is compatible with our Forged 80% Lowers and our Premium Fire/Safe Marked Billet 80% Lowers! Other manufacturer's billet 80% lowers may be compatible with this 80% lower jig, provided their lower receiver design adheres to mil-spec specifications.
One lower’s good practice for that first “from-scratch” AR build. Two lowers are great if you make a mistake. Three works, but let’s face it, you’re going to want to build more - especially since you’re buying the best 80% jig on the market, the Elite Builder. Stop the debate in your head. Just do it: Grab the five-pack combo and you’ll be ready to flesh out that AR armory like you’ve always dreamed. You’ll be glad you did.
Billet 80% Lower Receivers
What good are a bunch of junk lowers? We kept things to a high standard of quality by machining every billet 80% receiver from 6061-t6 aluminum using precise CNC. All receiver blanks ship with perfectly tapped and threaded mil-spec fittings and the gold-standard anodized coating to boot. Assembly is easier thanks to some innovations that ditch those roll pins, too:
- Integrated trigger guard
- Threaded bolt catch hole
- Threaded rear takedown hole
- Included screws and hex key
- “FIRE” and “SAFE engravings
- Type III hardcoat anodized finish
- Mil-spec buffer and parts kit fitment
- Broached mag well for easier reloads
