Allen Engineering AEM5K 5.56mm Steel Suppressor - FDE

Allen Engineering AEM5K 5.56mm Steel Suppressor - FDE

The Allen Engineering AEM5K is a compact hybrid suppressor that blends the proven performance of the AEM5 with the ultra‑short footprint of the AEM3. Built with an A‑length mount and the shorter AEM3 baffle stack, the AEM5K allows shooters to swap directly from a full‑size A‑mount suppressor using the exact same hardware—making it an ideal choice for users who run a single host but want multiple suppressor options for different applications.

Only slightly longer than an AEM3, the AEM5K delivers nearly identical sound and flash performance while offering the convenience of A‑mount compatibility. Its full 300‑series stainless steel construction ensures durability, heat resistance, and the classic OPS/AE tone that precision shooters value. Finished in FDE, the AEM5K provides a rugged, compact, and highly versatile solution for 5.56mm platforms built around the A‑mount system.
