Carb Insert 2in Tall 1.450in Diameter

The Carb Insert 2in Tall 1.450in Diameter is a precision-engineered restrictor plate spacer designed for tactical rifle systems and competitive shooters who demand control over gas flow dynamics. Built by Wehrs Machine—a trusted manufacturer in the precision firearms components space—this carburetor insert serves as a critical tuning component in the Wehrs Machine Spacer System, allowing shooters to optimize performance across varying ammunition loads and operating conditions. Whether you're fine-tuning an AR platform for suppressed fire, adjusting for subsonic loads, or balancing bolt carrier group cycling on a precision rifle, this insert delivers the mechanical consistency required in high-stakes shooting environments.

Manufactured from aluminum in natural finish, the Carb Insert 2in Tall 1.450in Diameter measures precisely 1.450 inches in bore diameter with a 2-inch tall profile, engineered to fit seamlessly into compatible Wehrs Machine systems. The aluminum construction provides weight savings critical in modern tactical platforms while maintaining the dimensional tolerances necessary for reliable gas regulation. At just 0.81 pounds, this spacer insert won't burden your rifle system, and its straightforward mechanical design eliminates unnecessary complexity—gas flows through the precisely dimensioned bore, creating a controlled pressure curve that stabilizes bolt carrier group movement and reduces carrier tilt, translating directly to improved reliability and reduced wear on critical components.

Law enforcement duty rifles, military platforms, and competition shooters benefit most from this restrictor plate insert when running unconventional ammunition or operating suppressors that alter system pressure dynamics. Installation requires familiarity with your specific Wehrs Machine Spacer System configuration; verify bore diameter and stack height compatibility with your existing components before purchase. This insert is ideal for shooters who've experienced carrier tilt, unreliable bolt lock-back on empty magazines, or inconsistent cycling with subsonic ammunition—giving you a proven mechanical solution to dial in your system precisely rather than relying on friction-dependent adjustments.
