Packer 14mm 1/8in Thick

The Packer 14mm 1/8in Thick is a crucial bump stop shim designed for operators and armorers who require precision in their tactical platforms. This component addresses a vital need in modern rifle systems by controlling bolt carrier group travel and managing recoil impulse through controlled spacing. It is ideal for building duty rifles, tuning competition platforms, or servicing military-pattern firearms.

Manufactured to exacting tolerances, the Packer shim measures precisely 1/8 inch thick with a 14mm inner diameter, allowing it to sit flush against buffer tube hardware without binding or shifting under recoil. Its lightweight profile ensures it does not introduce any detectable mass penalty to your system's cycle rate. Constructed from durable materials, this shim is engineered to withstand repeated chambering cycles and sustained fire, preventing excessive bolt carrier group rattle while maintaining the necessary headspace clearance for reliable feeding and extraction.

Law enforcement armorers, military gunsmiths, and serious civilian shooters benefit from the Packer shim to fine-tune bolt velocity, suppress carrier tilt, and extend component service life. Its compact design makes it compatible with standard AR-platform architectures and similar modular systems, ensuring versatility in various applications.
