Mi Alpha Blast Diverter Blk 1/2X28-9Mm
The Midwest Industries Alpha Blast Diverter is a muzzle blast management accessory designed for 9mm rifles and pistols with 1/2x28 threading. If you shoot unsuppressed and want to reduce the concussive force pushing back toward you and those nearby on the firing line, this diverter redirects muzzle blast forward and away from the shooter—a practical solution for reducing blast signature and improving shooting comfort, especially in indoor ranges or tactical training scenarios where muzzle blast is a real concern.
Built from 6061 aluminum with a steel endcap secured with threadlocker, the Alpha Blast Diverter is engineered in the USA for durability and reliability. At 9.8 ounces with a 4.5-inch overall length, it's substantial enough to be effective without being unwieldy. The 2.25-inch length from the rear to the vent holes and 1.950-inch outside diameter give it a balanced profile that works on most rifle and pistol platforms accepting 1/2x28 mounts.
This is a straightforward piece of gear—no moving parts, no complex operation. Thread it on, apply the included threadlocker, and let physics do the work. If you're tired of blast washing back over the firing line or dealing with the concussive kick of unsuppressed 9mm shooting indoors, the Alpha Blast Diverter is a no-frills way to push that energy downrange instead of back at your face.

Frequently Asked Questions
What thread pitch does the Alpha Blast Diverter fit?
The Midwest Industries Alpha Blast Diverter is designed for 1/2x28 threading, the standard pitch for most 9mm rifles and pistols.
Will this work on my 9mm pistol or rifle?
Yes, as long as your 9mm platform has 1/2x28 threaded muzzle. If your barrel is already threaded for a suppressor or muzzle brake, you can use this diverter as an alternative or upgrade.
Does the Alpha Blast Diverter come with threadlocker already installed?
The steel endcap is loctited in place at the factory. You'll want to apply fresh threadlocker when installing it on your barrel to ensure secure retention.

The diverter weighs 9.8 ounces, making it a relatively lightweight addition to your muzzle without excessive bulk.
