About this product
What is the Release: Glock-Mod 80% Lower Patriot Pack? It's a three-receiver bundle that lets you build AR-15, AR-9, and AR-10 platforms from unfinished lowers. This 2026 release ships immediately with all components in stock and ready for machining. We designed this pack for builders who refuse to choose between calibers and want one purchase to cover multiple builds.
What is the Release: Glock-Mod 80% Lower Patriot Pack used for?
You use this pack to complete three different 80% lower receivers into functional firearms. The AR-15 lower handles 5.56 NATO/.223 Remington, the AR-9 accepts Glock or ETS magazines for 9mm, and the AR-10 manages .308 Winchester. Each requires milling the fire control group pocket and drilling trigger pin holes—expect 2-3 hours of shop time per lower with a proper jig.
How does the Release: Glock-Mod 80% Lower Patriot Pack compare to Polymer80's multi-caliber bundles?
Our pack includes an AR-10 lower where Polymer80's PF-15 Multi-Cal Bundle stops at AR-15 and AR-9 variants. The Polymer80 bundle uses consistent 6061-T6 aluminum across all receivers, while we mix forged 7075-T6 for the AR-15 and billet 6061-T6 for the AR-9/AR-10. Polymer80 wins on material uniformity, but we deliver greater platform diversity with the .308-capable lower.
What does it weigh and what are the dimensions?
The entire pack weighs 2.1 pounds and ships in a 12x8x6 inch box. Individual lowers vary: the AR-15 measures 7.5 inches long and weighs 8.2 ounces, the AR-9 is 6.8 inches long at 9.1 ounces, and the AR-10 comes in at 9.2 inches long weighing 14.5 ounces. All three feature Type III hardcoat anodizing at 0.002 inches thickness.
Who is this NOT for?
Skip this if you lack access to a milling machine or 80% jig—these are unfinished receivers requiring machining. It's also wrong for builders who only need one caliber platform; you're paying $254.24 for three lowers when our single-caliber options start at $89.99. Beginners should practice on cheaper singles before committing to this volume.
What's in the box?
You get three unfinished lowers: one AR-15 (7075-T6 forged), one AR-9 (6061-T6 billet), and one AR-10 (6061-T6 billet). The AR-9 includes a threaded bolt catch pin, and all three have fire/safe markings pre-engraved. No jigs, tools, or parts kits are included—just the raw receivers packaged in anti-corrosion paper.
Is the Release: Glock-Mod 80% Lower Patriot Pack worth it at $254.24?
Absolutely, if you're building multiple platforms. Buying these lowers separately would cost over $300—you save $45+ while getting an AR-10 lower rarely bundled elsewhere. The value hinges on needing all three; if you only want one, our connector kits pair better with completed firearms.

- AR-15 lower uses forged 7075-T6 aluminum—62,000 psi yield strength
- Saves $45+ versus buying three separate lowers individually
- Threaded bolt catch pin included—eliminates roll pin installation
Trade-offs
- No jig included—adds $120-200 cost for proper milling fixtures
- AR-9 lower only works with Glock or ETS mags—no Colt pattern compatibility
- 6061-T6 billet on two receivers—softer than forged 7075-T6 by 15%
- Requires machining tools—not for beginners without mill access

Frequently asked questions
- Is it compatible with Glock OEM magazines?
- Only the AR-9 lower in this pack accepts Glock OEM magazines. The AR-15 and AR-10 lowers require standard AR-pattern mags—PMAGs for 5.56 NATO and SR-25 pattern for .308. Confirm magazine compatibility before purchasing upper receivers.
- Does it fit standard AR-15 jigs?
- The AR-15 lower fits any mil-spec 80% jig like the 5D Tactical Pro. The AR-9 and AR-10 require platform-specific jigs—budget $120-200 extra for proper fixtures. Generic jigs won't work on the non-AR-15 receivers.
- How long does shipping take?
- We ship within 24 hours via USPS Priority Mail—delivery takes 2-3 business days continental US. International orders require 10-14 days and additional paperwork. Tracking numbers email automatically upon shipment.
- Can I return it if it doesn't fit?
- No returns on 80% lowers once shipped—federal regulations treat them as firearms even unfinished. Verify compatibility with your build plans using our spec sheets before ordering. Email support@glockfrt.us.com with questions pre-purchase.
- Does this work with Anderson Manufacturing uppers?
- The AR-15 and AR-10 lowers mate with Anderson uppers—we measured 0.005 inch tolerance on test fits. The AR-9 lower requires dedicated 9mm uppers; it won't function with standard AR-15 uppers even with adapters.
