Key features and tactical considerations

KAC Knight’s Armament quad rail

The KAC quad rail is a high-quality mounting interface known for rigidity and repeatable zero when mounting optics or lasers. For precision shooting or duty use, this rail simplifies accessory placement and keeps the sight picture consistent under recoil. Expect plenty of real estate for lights and backup irons while retaining a slim center profile for natural handling.

LE serial number M4 & factory box

An LE serial number M4 indicates law-enforcement provenance which can affect collector value and traceability. The included factory box helps verify original configuration and condition—important when assessing a used firearm’s history. These elements can make the difference when prioritizing long-term serviceability or resale value. View product details and pricing on the shop page for complete condition notes.

Practical fit and use cases

On patrol, range training, or as a precision-focused setup for competitions, this Colt platform and the KAC rail allow quick transitions between roles. With its Semi Auto classification, operators can install a matched optic and backup iron sights to maximize accuracy, or fit a compact red dot for fast target acquisition.

Buying considerations

When evaluating this COLT M4 CARBINE at $1599.99, confirm the rail mounting torque, inspect the upper/lower fit, and verify the LE serial documentation if provenance matters.
