Silencerco Ac1278 Asr Black Nitride 9/16"X24 Lh Threads 30 Cal

The SilencerCo ASR (Accept / Suppress / Repeat) adapter system is a modular quick-disconnect platform that lets you attach and detach SilencerCo suppressors rapidly without losing zero. This ASR Black Nitride adapter features 9/16"×24 left-hand threads and is rated for .30 caliber rifles, making it a solid foundation for building a flexible suppressor setup across multiple rifles in that caliber class. Whether you're running a bolt gun, semi-auto, or anything in between, the ASR system's repeatability and ease of use have made it a go-to choice for serious hunters and shooters who want suppressor versatility without compromise.

The black nitride finish provides corrosion resistance and a clean, professional appearance. This adapter is designed to work with SilencerCo's ASR-compatible suppressors, so you can swap cans between rifles quickly—ideal if you're consolidating gear across multiple platforms or want to move a suppressor between hunting seasons. The left-hand thread orientation suits rifles with LH-threaded muzzles, which is less common than right-hand but essential if that's what your barrel requires.

Like all SilencerCo products, this adapter reflects precision engineering and real-world testing in the field. It's a component built for hunters and shooters who demand reliability when it matters.

Frequently Asked Questions

What rifles does this ASR adapter fit?

This adapter is designed for .30 caliber rifles with 9/16"×24 left-hand threaded muzzles. Verify your rifle's muzzle thread pitch and direction before purchasing—left-hand threads are less common and not interchangeable with right-hand.

Can I use this adapter with different SilencerCo suppressors?

Yes. This ASR adapter will work with any SilencerCo suppressor designed for the ASR quick-disconnect system, allowing you to swap suppressors between compatible rifles without tools.

Does this come with a suppressor?

This is the adapter only. A SilencerCo ASR-compatible suppressor is purchased separately.

What's the benefit of the ASR quick-disconnect system?

The ASR system lets you attach and remove suppressors quickly while maintaining point-of-impact consistency, so you can move a suppressor between rifles or take it off without resighting your scope.
