The Kaw Valley Precision 9mm Linear Compensator in 1/2×28 with a black finish (Kaw Valley Precision part no. BLKLINEAR9MM12X28TPI) is the thread option the maker lists for AR-9 and Kel-Tec Sub 2000 Mk2 barrels. A linear comp collects muzzle gas and redirects it away from the shooter, which lowers the perceived noise and concussion at the shooter’s ear, and bystanders benefit too. Kaw Valley Precision cites close-quarters shooting, competition, varmint hunting, law enforcement and indoor ranges as uses. No crush washer is needed to install it.
