Product Description The Troy Industries Delta CX Rail is a precision-engineered 12" modular quad rail system designed for AR-15 platform rifles. Featuring a two-piece drop-in design, this free-float handguard installs in minutes with absolutely no gunsmithing required and no modification to the firearm. Built around Troy&';s rock-solid rotary clamping system, the Delta CX Rail does not require removal of the delta ring, barrel nut, or fixed front sight, making installation straightforward and hassle-free. Two built-in QD swivel mounts are integrated directly into the rail, adding functionality without extra hardware. The modular design allows the addition of smaller Picatinny rail segments (sold separately) wherever needed, avoiding the unnecessary weight of a full-length quad system. Constructed from lightweight aluminum with a durable black finish, this rail is Made in the USA and designed specifically for firearms with A-frame sights. Note: Not compatible with .308 ARs and Ruger AR-556 due to the built-in QD at the bottom of the A2 front sight.
