PCQ G2 – AR 15 Carbine Drop In Quad Rail

Upgrade your AR15, M4, or M16 carbine with the IMI Defense™ PCQ G2 AR15 Carbine Drop-In Quad Rail — a lightweight polymer handguard built for accessory mounting, fast installation, and improved rifle versatility.

Constructed from durable fiber-reinforced polymer, the PCQ G2 gives shooters a strong, lightweight alternative to aluminum quad rails while keeping the rifle slim and easy to handle. Its two-piece drop-in design installs quickly with no gunsmithing required, making it a practical upgrade for carbine-length rifles.

The handguard features Mil-Spec 1913 Picatinny rails at the 3, 6, 9, and 12 o’clock positions, allowing flexible mounting for lights, grips, lasers, sling accessories, rail covers, and other tactical gear. The continuous upper rail includes numbered T-marks for more precise and repeatable accessory placement.

A single QD swivel mounting point on the bottom adds sling compatibility, while the ultra-slim 1.5" width and compact 6.65" overall length help maintain a clean, low-bulk carbine setup.
