Silencerco Ac2608 3-Lug Muzzle Device M13.5X1Lh Threads 45 Acp

The SilencerCo AC2608 is a 3-lug muzzle device engineered for .45 ACP pistols and carbines that require a direct-thread suppressor interface. Built for shooters who want reliable suppressor attachment without the bulk of other mounting systems, this muzzle device features M13.5×1 left-hand threads and the proven 3-lug quick-disconnect design that SilencerCo suppressors are built around. Whether you're running a .45 ACP pistol with a threaded barrel or a dedicated suppressor host, the AC2608 gives you a rock-solid foundation for hearing protection and reduced muzzle rise.

Left-hand threads mean this muzzle device is specifically indexed for counterclockwise installation—critical for proper fitment and suppressor alignment. The 3-lug design is faster and smoother to engage and disengage than traditional mounts, and it's battle-tested across SilencerCo's suppressor line. If you already run SilencerCo suppressors or are building a .45 ACP setup that demands quick-change capability, this muzzle device is purpose-built for that mission.

Precision machining and durable materials ensure this adapter will handle the pressures of .45 ACP without degradation—no rocking, no walkoff, no surprises when you need it. It's the kind of straightforward, reliable hardware that lets you focus on shooting instead of wrestling with gear.

Frequently Asked Questions

Will this muzzle device work with my .45 ACP pistol?

Yes, provided your barrel has M13.5×1 left-hand threads. Verify your pistol's thread pitch before purchasing—incorrect threads will not fit safely.

Is this compatible with SilencerCo suppressors?

The AC2608's 3-lug design is built to interface with SilencerCo's 3-lug suppressor line. Confirm your specific suppressor model supports 3-lug mounting.

What does "left-hand threads" mean?

Left-hand threads install counterclockwise (reverse of standard). This device is threaded for left-hand attachment only—forcing it onto a right-hand barrel will cause damage.

Can I use this muzzle device without a suppressor?

The AC2608 is designed as a suppressor mounting interface. Use it as part of a complete suppressor system for which it is rated.
