Overview

The PSA Sabre-IC Ambi Receiver Set is a matched forged upper and lower built for 6mm ARC and .338 ARC, machined from 7075-T6 aluminum and finished in Cerakote so the two receivers tone together. It carries the same three Sabre upgrades as the AR-15 Sabre Enhanced set, a pre-installed ambidextrous bolt catch and release, a threaded set screw in place of the bolt-catch roll pin, and a flared magwell with an integral trigger guard, but on a magwell cut for the ICAR pattern instead of standard AR-15 magazines. It launched June 12, 2026 in six finishes: Champagne, FDE, Burnt Bronze, Black, Moss Green, and Blue Titanium.

The defining constraint is the magazine. The Sabre-IC runs the Magpul PMAG 25 ICAR GEN M3 and nothing else, a 25-round polymer magazine built around the SureFire ICAR and LWRCI Six8 magwell pattern and optimized for 6mm ARC and .338 ARC. A standard AR-15 magazine will not seat in this lower, and the ICAR magazine will not run in a standard AR-15 lower, so the receiver set and the magazine are a closed system. Budget for ICAR magazines as part of the build cost.

Everything north of the magwell stays familiar. The upper carries engraved T-marks and a thermal-fit barrel extension, and the lower takes mil-spec triggers, safeties, pins, grips, and charging handles. For the bolt and barrel, PSA points builders at its E4 bolt and 6mm ARC barrels, and the lower will run most 6.5 Grendel bolts since 6.5 Grendel and 6mm ARC share a bolt face. Black runs $329, the Cerakote finishes run $349, and a bundle with five PMAG 25 ICAR magazines runs $499.
