80% Lower Fire/Safe Marked – Raw
About this product
The Trigger Logic 80% Lower Fire/Safe Marked – Raw is a forged 7075-T6 aluminum AR-15 receiver blank requiring final machining by the builder. This raw, unfinished lower features permanently engraved FIRE/SAFE selectors and a broached magwell ready for immediate jig setup and milling operations. It ships unfinished specifically for builders who want complete control over their final surface treatment and coloration.
What is the Trigger Logic 80% Lower Fire/Safe Marked – Raw used for?
This 80% lower serves as the foundation for building a custom AR-15 rifle without requiring an FFL transfer. You'll need to complete the fire control group pocket, trigger pin holes, and safety selector recess using a compatible jig like the 80% AR-15 Easy Jig® Gen 1. The raw finish means you can anodize or Cerakote after machining to match your exact build specifications.
How does the Trigger Logic 80% Lower Fire/Safe Marked – Raw compare to the 80% Lower Fire/Safe Marked – Anodized Black?
The raw version provides greater finishing flexibility but requires additional steps before use. While the anodized black version ships ready for immediate assembly after machining, this raw lower saves approximately $25-35 on upfront cost but requires you to source and apply your own finish. For builders planning custom coatings or who have anodizing capabilities, the raw version offers better value.
What does it weigh and what are the dimensions?
The unfinished lower weighs 8.2 ounces with dimensions measuring 7.5 inches long, 2.25 inches wide, and 1.5 inches thick at the buffer tube interface. The broached magwell opening measures exactly 0.998 inches wide to accommodate standard AR-15 magazines without modification. These dimensions match mil-spec patterns within 0.003-inch tolerance.
Who is this NOT for?
This product is not suitable for beginners without access to milling equipment or proper jig alignment tools. If you lack experience with machining operations or don't own a drill press capable of maintaining 0.001-inch tolerances, consider starting with our jig alignment guide first. It's also not ideal for immediate builds since finishing adds 2-3 days to your timeline.
What's in the box?
You receive exactly one raw 80% lower receiver with no additional components or hardware. The package includes only the unfinished aluminum forging with pre-engraved markings and broached magwell. You'll need to supply your own jig, end mills like the 5/16″ High Speed End Mill, and finishing materials.
Is the Trigger Logic 80% Lower Fire/Safe Marked – Raw worth it at $89?
At $89, this represents solid value for experienced builders who prioritize finishing control. The 7075-T6 aluminum construction provides superior strength compared to 6061 alternatives, and the deep engraving ensures selector markings remain legible after aggressive finishing. For builders planning custom cerakote patterns or specialty anodizing, the raw version eliminates the cost of stripping existing finish.

Pros & cons
What works
- Forged 7075-T6 aluminum - 35% stronger than 6061-T6 equivalents
- Deep-engraved FIRE/SAFE markings remain visible after aggressive finishing
- Broached magwell with 0.998-inch opening for drop-free magazine compatibility
- Weighs 8.2 oz unfinished - lighter than billet alternatives by 1.5-2 oz
Trade-offs
- Raw finish requires additional $40-80 for professional anodizing/Cerakote
- No included jig or tools - adds $120-200 to total build cost
- Tighter tolerances require machining experience - not beginner friendly

Frequently asked questions
- Is it compatible with standard AR-15 parts kits?
- Yes, it accepts all mil-spec AR-15 lower parts kits including triggers, pistol grips, and buffer tubes. The fire control group pocket requires final machining to precise dimensions outlined in our jig documentation. Tolerance is maintained within 0.002 inches for proper parts fitment.
- Does this work with Polymer80 jigs?
- It's designed specifically for Polymer80 jig systems including Gen 1 and Gen 2 Easy Jigs. The alignment pin holes are drilled to 0.154-inch diameter matching Polymer80's specifications. We recommend consulting our <a href="/blog/80-lower-receiver-jig-alignment-pin-specifications/">alignment pin guide</a> for proper setup.
- How long does shipping take?
- Most orders ship within 24 hours via USPS Priority Mail (2-3 days transit). Expedited shipping options are available for same-day dispatch if ordered before 2 PM EST. International orders require 7-10 business days and proper export documentation.
- Can I return it if I mess up the machining?
- No, once machining has begun the product cannot be returned due to ATF regulations regarding serialization requirements. We recommend practicing on cheaper materials first - approximately 90% of machining errors occur during the first FCG pocket operation.
- Does this work with ambidextrous safety selectors?
- Yes, the safety selector pocket is cut to standard dimensions accommodating most ambidextrous selectors including Radian Talon and Battle Arms Development models. The pocket measures 0.375 inches wide with 0.005-inch clearance for smooth operation.
