When you build a reliable rifle, the lower receiver is more than a parts shelf — it’s the backbone that defines fit, feel, and long-term durability. Whether you’re assembling a competition rig, a range trainer, or a precision-minded cartridge conversion, selecting a lower that blends rugged construction with thoughtful ergonomics is critical for consistent performance.
SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER
Design and Materials: Purpose-Built from 7075-T6
The SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER is machined top to bottom from forged 7075-T6 aluminum — the same high-strength alloy favored for service-grade receivers. That foundation provides a high strength-to-weight ratio and proven longevity under repeated use. The Overthrow’s open mag well helmet design not only speeds reloads but also gives the lower a distinct tactical profile that blends form and function.
Battle-Worn Aesthetic with Functional Details
The Overthrow is defined by intentional surface treatments: battle worn dents, sword gashes and crack lines sculpted into the exterior. These aren’t just cosmetic flourishes; they create a unique visual language that stands out on the range while maintaining full compatibility with standard components. The receiver carries a Multi caliber mark, signaling broad compatibility for builders who plan to change calibers or create multi-role platforms.
Compatibility and Practical Use
One of the most practical strengths of the SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER is its mil-spec compatibility. It accepts all mil-spec internal parts and mates with aftermarket mil-spec upper receivers without modification. That means you can drop in standard lower parts kits, buffers, and stocks from the parts bin or a trusted vendor and achieve a reliable, repeatable build.
Magazine compatibility is equally straightforward: the Overthrow works with GI standard issue magazines and PMags. For shooters who value interchangeability and logistics simplicity, that compatibility minimizes surprises during builds and when sourcing spare mags.
Multi-Caliber Flexibility
The Multi caliber mark on the SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER is an important indicator for progressive builders. Whether you’re running common 5.56/.223 platforms today and considering an upper for a different cartridge later, this lower supports a modular approach. That flexibility is ideal for range-sharpening, training rigs, or users who want a single core lower that adapts to multiple mission profiles.

Installation Notes and Builder Tips
The SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER ships stripped — it requires a lower parts kit, buffer, and stock of your choosing to complete the build. For first-time builders or those stepping up from polymer lowers, keep these points in mind:
- Use a mil-spec lower parts kit to ensure proper fit with the Overthrow’s internal geometry.
- Select a buffer weight and stock that match your intended gas system and recoil characteristics for best reliability.
- When installing the trigger group and safety, maintain correct pin alignment and torque to avoid premature wear.
- Because the Overthrow is machined from 7075-T6, threading or modification should be done only by qualified armorers to preserve material integrity.
Assembly Workflow
Start with test-fitting the bolt catch, trigger group, and safety before final pinning. Drop-in triggers that are mil-spec will interface cleanly, but if you opt for a precision trigger, verify sear engagement and safe reset before live firing. The open mag well helmet design makes magazine insertion smoother — a benefit during both timed drills and casual range sessions.
Why Choose the Overthrow for Your Next Build
For builders who want a lower that combines rugged reliability with standout aesthetics, the SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER is a compelling choice. It blends 7075-T6 durability with practical features like mil-spec compatibility and an open mag well. The battle-worn visual treatment gives the platform personality without impacting performance.

Field Performance Expectations
Expect the SHARPS BROS MFG OVERTHROW STRIPPED LOWER RECEIVER to offer a consistent platform for accurate, repeatable shooting when paired with quality uppers and components. The 7075-T6 construction resists deformation under stress and helps maintain solid pin alignment — both essential for repeatable accuracy. The open mag well accelerates reloads, and the Multi caliber designation future-proofs your investment for caliber conversions or varied mission sets.
