The Dead Air Keymicro 1/2x28 Taper Adapter is a quick-disconnect muzzle interface built for .22 caliber rifle suppressors. This adapter lets you mount Dead Air Keymicro or compatible KeyMo suppressors to your .22 rifle with a 1/2-28 SIG TAPER threaded muzzle. If you run a .22 host rifle and want modular suppressor mounting without the weight and bulk of a full-sized flash hider, this adapter strips the job down to essentials—it threads on, stays put, and gets out of the way.
The 1/2x28 SIG TAPER threads are standard on many .22 rimfire platforms and modern centerfire rifles in compact cartridges. This adapter uses the same quick-change mounting technology Dead Air engineered into their industry-standard KeyMo system, so you get proven reliability in a smaller footprint. Built from 4140 HT alloy steel with black nitride finish, it's tough enough for regular use and won't rust or corrode in the field or on the range.
Whether you're running a .22 for varmint work, subsonic plinking, or training, the Keymicro adapter lets you swap suppressors between compatible hosts quickly and securely. It's a straightforward tool for hunters and shooters who want sound reduction without the fuss of direct-thread mounting.

Frequently Asked Questions
What caliber and thread pattern does this adapter fit?
The Keymicro 1/2x28 Taper Adapter is designed for .22 caliber rifles with 1/2-28 SIG TAPER threaded muzzles. It will not fit other thread pitches or taper angles.
Which suppressors can I use with this adapter?
The adapter is compatible with Dead Air Keymicro suppressors and other KeyMo-compatible suppressors designed for .22 caliber. Check your suppressor's documentation to confirm KeyMo or Keymicro compatibility before purchase.
Can I use this adapter as a standalone muzzle device without a suppressor?
The adapter is designed as a mounting interface for suppressors. While it can thread onto your barrel, it functions primarily to attach a compatible quick-change suppressor, not as a standalone flash hider or muzzle brake.
Is this the same quick-change technology as Dead Air's KeyMo system?
Yes. The Keymicro adapter uses the same proven quick-disconnect design that Dead Air developed for the KeyMo system, scaled for smaller-bore applications.
