Palmetto State Armory's new Sabre IC receiver sets are here! These ambidextrous setups are built around the Magpul ICAR magazine for cartridges like the 6mm ARC and 338 ARC. Keep reading for all the details.PSA @ TFB: TFB 1,000 Round Review: PSA Sabre 15 (Duty Grade Or Don't-y Grade?) [SHOT 2025] PSA New Releases & Concept Guns TFB Review: PSA Soviet Arms "Krink" in 5.56 PSA AK-104 3000 Round Review PSA Drops The Hottest Mixtape EverThe Magpul ICAR architecture will be familiar to some AR15 users. It is an update on the older LWRC Six Eight platform, which was optimized for the 6.8 SPC caliber. Though that round fell out of favor, the magazine and receiver sets it spawned are a perfect fit for newer calibers like the 6mm ARC. This setup offers a great starting point for a build in one of the compatible calibers.PSA showed off complete rifles using these receivers at SHOT 2026, but the parts are beating the full guns to market. The Sabre IC receivers retail for $329 in black, or $349 in an assortment of Cerakote colors. For $499 you can get a receiver set and five ICAR magazines. All models are in stock at PSA as of writing. Individual 25-round windowed ICAR mags are available in black or FDE for $37.99 each. All images from PSA. From the manufacturer:"Based on our Sabre-15 Enhanced receiver sets, the Sabre-IC receiver set is purpose-built for Magpul ICAR magazine compatibility, making it the right foundation for a 6mm ARC or similar caliber build.The upper receiver features engraved T-marks and provides a thermal fit for your barrel. The lower receiver includes an ambidextrous bolt catch/release and features an integral trigger guard and flared magwell. Both the upper and lower receivers are compatible with AR-15 pattern parts."
