Moriarti AR-15 Dual Side Charging Billet Upper Receiver with BCG – Ambidextrous

AR-15 Line

Upgrade your AR-15 platform with the Dual Side Charging Billet Upper Receiver, engineered for versatile operation, durable construction, and distinctive styling. CNC-machined in the USA from aircraft-grade 6061 billet aluminum, this upper features an ambidextrous side-charging system, skeletonized Picatinny rail, and an included proprietary bolt carrier group.

Unlike conventional AR-15 upper receivers, this design eliminates the standard rear charging handle in favor of a screw-in side-charging handle mounted directly to the bolt carrier group. The charging handle can be installed on either side, allowing shooters to configure the upper for left-side or right-side operation.

The receiver features a beveled ejection port, M4 feed ramps, and a durable Class III hardcoat anodized finish. Its skeletonized 1913 Picatinny rail provides a distinctive appearance while maintaining compatibility with appropriate rail-mounted accessories.

The included proprietary side-charging BCG comes configured with a 5.56 NATO bolt. The bolt can be exchanged for compatible standard-cut bolts to accommodate other calibers, subject to proper component compatibility.

100% Made in the USA, this billet upper receiver offers a modern alternative to traditional rear-charging AR-15 configurations.
