Fn 20-100816 545 Accessory Comp Kit Fde

The FN 545 Accessory Comp Kit in FDE gives your FN 545 Tactical or FN 545 MRD a serious upgrade in shootability without requiring a gunsmith or factory work. This kit pairs FN's quick-detach compensator with a proprietary QD barrel, letting you install or remove the comp in minutes using nothing but your hands. It's the same recoil-management technology FN introduced on the 509 CC Edge, now available for the 545 platform.

The compensator itself is the real game-changer here. Its V-style ports redirect muzzle gases outward and downward, which does two critical things: it cuts felt recoil noticeably and keeps flash and gas out of your line of sight so your sight picture stays locked between shots. That translates to faster, more accurate follow-ups—whether you're running drills at the range or training for defensive use. The stainless steel construction is finished with a hardened PVD coating that handles standard and self-defense ammunition equally well, so you don't have to fuss with load-specific tuning.

What makes this kit practical is the threadless QD design. No muzzle threading, no timing concerns, no permanent modifications to your barrel. The compensator locks on securely and comes off just as easily. You'll still use your factory FN 545 recoil spring with no changes needed—FN engineered this to work as a drop-in system on your existing setup.
