Description
The CAT Spooky A1 Flash Hider is a 5.56mm muzzle device that threads onto a 1/2×28 barrel and lets you mount a CAT silencer to your host rifle. It is made from 4140 steel with a Black Nitride finish, and it adds only 1.26-inch of length to the muzzle. The A1 is the 5.56mm version of the Spooky line, which CAT also offers in a 14.5PW version and a 7.62mm A2 version. It suits an AR-15 owner who wants one muzzle device that handles flash reduction now and a suppressor mount later. CAT also lists a 1x16LH QD attachment on the design.
Key Specifications
- The caliber rating is 5.56mm, which matches the 1/2×28 thread used on most AR-15 barrels.
- The barrel attachment is 1/2×28, the standard thread for 5.56mm rifles.
- Overall length is 1.88-inch, so the device stays compact at the muzzle.
- Weight is 2.7 oz, light enough that it does not upset the balance of a carbine.
- The finish is Black Nitride over 4140 steel, a hard coating that resists wear and corrosion.
