Lyman, the trigger is not caliber specific, it will work in any AR15 lower. Have a great day!

any AR lower caliber does not matter

This will work in any Standard AR15 Lower.
Binary triggers are kind of cool but honestly I like the "Graves Automatic Reset (A.R.T) Trigger is much faster and more controllable.

Lyman, this will work in any caliber AR lower receiver. The trigger is not caliber dependent. Cheers and stay safe!
