Pros & cons
What works
- Weighs 8.2 oz — 1.3 oz lighter than aluminum Mil-Spec lowers

- Ships within 24 hours — faster than industry average 3-5 day processing
- Saves 58% vs completed lowers — $63.27 vs $150+ finished units
Trade-offs
- No completion jig included — adds $50-120 to total build cost
- Requires milling machine — not suitable for drill-press only setups
- Limited to Glock triggers — won't accept standard AR trigger groups without modification
- No magazine compatibility — strictly trigger housing, requires separate lower for Glock mags

About this product
The Glock-Mod Polymer80 G150 AR-15 80% Lower Receiver ONLY is a specialized 80% lower receiver designed for builders who want a Glock-style trigger housing integrated into an AR-15 platform. This receiver ships unfinished and requires machining to complete, making it ideal for experienced builders who understand firearm regulations. We've shipped over 731 units since late 2024 to customers across the United States.
What is the Glock-Mod Polymer80 G150 AR-15 80% Lower Receiver ONLY used for?
This receiver is used for building custom AR-15 rifles with Glock-compatible trigger systems. It accepts standard Glock-style drop-in trigger packs like our Glock-Mod BLEM Standard Semi-Auto 6061 Aluminum Flat Glock Trigger, allowing for rapid trigger upgrades without gunsmithing. The unfinished design requires milling and drilling to complete, making it suitable for builders who want full control over their lower's specifications.
How does the Glock-Mod Polymer80 G150 compare to the Polymer80 PF940V2?
The G150 outperforms the Polymer80 PF940V2 in trigger compatibility while being more specialized. The G150 weighs 8.2 oz compared to the PF940V2's 9.5 oz, and its Glock-style trigger housing allows direct drop-in installation of performance triggers like our Glock-Mod 3.5lb Modified Cut Nub Connector. However, the PF940V2 offers broader magazine compatibility while the G150 is optimized specifically for Glock-style systems.
What does it weigh and what are the dimensions?
The receiver weighs 8.2 ounces and measures 7.5 inches in length, 2.1 inches in width, and 1.8 inches in height. These dimensions match standard AR-15 lower receiver specifications while maintaining compatibility with Mil-Spec upper receivers. The weight is 1.3 ounces lighter than many aluminum counterparts, reducing overall build weight.
Who is this NOT for?
This receiver is not for beginners or those unwilling to complete machining work. It requires specialized tools including a drill press, milling machine, and appropriate jigs to complete the fire control group pocket and trigger pin holes. Builders must also understand federal and state regulations regarding 80% receivers before purchase.
What's in the box?
The box contains one unfinished Polymer80 G150 lower receiver weighing 8.2 oz, one set of installation instructions, and discreet packaging materials. No jigs, tools, or fire control components are included—this is strictly the raw receiver. Customers will need to source their own completion jig and appropriate machining equipment.
Is the Glock-Mod Polymer80 G150 worth it at $63.27?
At $63.27, this receiver offers exceptional value for builders seeking Glock trigger compatibility. Compared to completed lowers costing $150+, the G150 provides 58% savings while allowing custom fitting of trigger components. When paired with our Glock-Mod 3.5lb Modified Cut Nub Connector, it creates a superior trigger system than most factory AR setups.

Frequently asked questions
- Is it compatible with standard AR-15 upper receivers?
- Yes, the G150 maintains full Mil-Spec dimensions and accepts any standard AR-15 upper receiver. The lower measures 7.5 inches in length with standard pin spacing, ensuring compatibility with 99% of commercial uppers without modification.
- Does it fit Glock magazines?
- No, this receiver uses standard AR-15 magazine wells but is designed for Glock-style trigger systems. You'll need a dedicated Glock magazine lower or adapter for magazine compatibility—this receiver only accepts the trigger mechanism, not the magazines.
- How long does shipping take?
- We ship from our Dallas, TX warehouse within one business day via USPS or UPS. Most continental US orders arrive within 3-5 business days from shipment date, with tracking provided for all orders.
- Can I return it if it doesn't fit?
- No returns are accepted on 80% receivers once machining has begun due to federal regulations. We recommend verifying compatibility with your build plans and local laws before purchasing—email our support team with specific questions before ordering.
- Does this work with binary triggers?
- Yes, when properly machined, the G150 accepts most binary trigger systems including Franklin Armory BFSIII. However, trigger compatibility depends on proper pocket dimensions—we recommend using our <a href="/products/⚡-new-glock-mod-blem-standard-semi-auto-6061-aluminum-flat-glock-trigger/">Glock-Mod BLEM Standard Semi-Auto Trigger</a> for guaranteed fitment.
