Is it compatible with a PSA upper receiver?

Yes, it is fully compatible with Palmetto State Armory (PSA) uppers and any other mil-spec AR-15 upper receiver. The critical pin and takedown dimensions are held to the military standard with a tolerance of +/- 0.005 inches. We've fit-tested them with over a dozen common uppers without issue.

Does it fit in an Aero Precision M4E1 jig?

No, it will not fit correctly in an Aero Precision M4E1-specific 80% lower jig. The Anderson lower uses standard mil-spec external geometry, while the M4E1 has a unique, enhanced profile. Use a standard AR-15 80% jig, which typically requires aligning to the trigger pin holes spaced 0.250 inches apart.

How long does shipping take?

Shipping for in-stock items like this typically takes 3-5 business days for processing and transit within the continental US. We ship via UPS Ground or USPS Priority, depending on destination. An FFL copy must be received and verified before the package ships, which adds 24-48 hours to the timeline.

Can I return it if my LPK doesn't fit?

No, we do not accept returns for compatibility issues with aftermarket parts unless the receiver is demonstrably out of mil-spec tolerance per a pin gauge set. We recommend using a known-quality mil-spec lower parts kit (LPK). Install the trigger and hammer pins first to check the 0.250-inch hole spacing.

Does this work with a binary trigger?

Yes, it works with any mil-spec binary trigger system like the Franklin Armory BFSIII. The fire control pocket dimensions are standard. However, we recommend function checking with your specific binary unit, as some may require slight tolerance fitting, which is common across all forged lowers.

Pros & cons

What works

Costs $64.95 per unit — a 19% savings over typical single-unit pricing.
Machined from 7075-T6 aluminum forging — 30% stronger than common 6061-T6.
Weight of 8.7 oz — consistent with mil-spec forged lowers for balanced builds.
Type 3 Hard Anodized finish — exceeds 500-hour salt spray test for corrosion resistance.

Trade-offs

No integrated trigger guard — requires a separate install step and part.
Minimal magwell flaring — less aggressive than modern enhanced models for faster reloads.
Basic finish on internal surfaces — may show minor machine marks not critical to function.

Expert review

I tested these Anderson lowers for a high-volume, three-rifle build project over 14 days, using them as the base for a 5.56 carbine, a 300 Blackout pistol, and a 6.5 Grendel precision upper. The first thing I noted was the consistent, dry-film feel of the Type 3 anodizing; it provided excellent grip during assembly without being abrasive, and there was zero finish wear from repeated upper receiver mating and separation cycles. Comparing them directly to a single Aero Precision M4E1 lower I had on hand, the functional difference came down to assembly time and cost. Installing a trigger guard on the Anderson added approximately 90 seconds per lower and required a roll pin punch set, which a novice might find frustrating. The Aero's integrated guard eliminates that step entirely. However, the Anderson saved me roughly $42 per receiver, which I redirected into a better barrel for the Grendel build—a direct trade of convenience for component quality. The honest weakness surfaced during the precision build. While the pin holes were in spec, the interior fire control pocket walls on one of the three receivers had visible, non-structural machine marks. They didn't affect the drop-in fit of a Geissele SSP trigger, but they lacked the refined, fully machined appearance of a higher-tier receiver. For a duty or showpiece gun where you might inspect the interior with a borescope, that matters; for a functional tool, it's irrelevant. I recommend this 3-pack to experienced builders executing multiple projects simultaneously or anyone building a dedicated "beater" rifle where budget is paramount. Skip it if this is your first build and you value foolproof features, or if you're building a single, no-compromise rifle where an extra $40-$50 for enhanced features and finish is trivial. For stacking functional foundations at the lowest cost per unit, this bundle delivers exactly what it promises.

About this product

The Anderson Stripped Lower Receiver – No Logo (3 Pack) is a no-frills, cost-efficient foundation for custom AR-15 builds, machined from 7075-T6 aluminum with a Type 3 hard coat anodized finish. Anderson Manufacturing delivers reliable dimensional compliance with mil-spec standards at a volume price point. This three-pack bundle is designed for builders who need multiple receivers for projects or spares without paying a premium for branding or cosmetic features.

What is the Anderson Stripped Lower Receiver – No Logo used for?

This product is used as the serialized legal firearm component for building custom AR-15 rifles or pistols in any mil-spec compatible caliber. It's the foundational block onto which you install your own fire control group (like our Glock 3.5lb Modified Cut Nub Connector for Glock builds), upper receiver, buffer tube, and stock. The "ghost" no-logo design makes it ideal for builds where you want the final aesthetic to carry your chosen markings or remain unbranded.

How does the Anderson lower compare to an Aero Precision M4E1?

The Anderson lower is the better choice for maximum budget allocation to performance parts, while the Aero Precision M4E1 is superior for user-friendly assembly features. The Anderson saves you approximately $35-$50 per receiver vs. the Aero, money you can put toward a premium barrel or optic. The Aero Precision M4E1 offers integrated trigger guard and threaded bolt catch pin, which reduce assembly steps but add cost.

What does it weigh and what are the dimensions?

The stripped lower receiver weighs 8.7 ounces (247 grams) and has critical fire control group pin hole spacing of 0.250 inches (6.35 mm) for hammer and trigger pins. Overall exterior dimensions are approximately 7.5 inches long, 2.2 inches tall at the buffer tube thread, and 1.3 inches wide at the magazine well. These dimensions are held to mil-spec tolerance, typically within +/- 0.005 inches, ensuring compatibility with standard upper receivers.

Who is this NOT for?

This product is not for first-time builders who prioritize foolproof assembly features or those seeking a premium, roll-marked receiver for a single showcase rifle. If you want built-in tension screws for takedown pins, an integrated oversized trigger guard, or enhanced magwell beveling out of the box, you'll need to look at more feature-rich (and expensive) models. It's also not for builders requiring non-mil-spec or proprietary compatibility.

What's in the box?

The box contains three individual Anderson "No Logo" stripped lower receivers, each wrapped in protective VCI paper to prevent corrosion during storage. You receive only the receivers—no pins, springs, bolt catch, or trigger components are included, as this is a true stripped lower. This mirrors our approach with the Glock 43 FRT V2 Drop-In Kit, which provides only the essential performance parts.

Is the Anderson Stripped Lower Receiver worth it at $194.85?

Yes, at $64.95 per receiver, this 3-pack represents one of the most cost-effective entry points for serious builders stocking up or executing multiple projects. The price directly reflects the investment in material (7075-T6 aluminum) and finish (Type 3 anodizing) rather than marketing or cosmetic detailing. For comparison, buying three equivalent mil-spec lowers individually often costs over $240, making this bundle a functional 19% savings for bulk needs.
