Operation is fast and intuitive, with a factory-reversible sidelever that delivers a smooth cycling action, now integrated into the strengthened upper rail for added durability. The manual AR-style safety ensures confident handling, while the ambidextrous FX UG1 AR-style grip and adjustable buttpad cater to a wide range of shooting styles.

The M4 Compact comes equipped with a high-capacity Side-Shot magazine , offering 35 shots in .177 and 28 shots in .22 , alongside a magnetic single-shot tray for precision shooting disciplines. At its core is the AMP MKII regulator, providing consistent air delivery with high-speed recovery, supported by FX’s renowned Quick Tune System. This external setup allows tool-free macro and micro adjustment of the hammer spring and valve flow, enabling quick and precise tuning without the need for disassembly.

For mounting optics and accessories, the rifle features a Picatinny rail with 30 MOA incline, plus side and underside accessory rails. The ½" x 20 UNF threaded muzzle allows for moderator attachment, ensuring stealth when required.
