The Kaw Valley Precision Plan B Muzzle Brake in 5/8×24 (brand part no. KVPPLANBBRAKE02) threads onto larger-caliber AR barrels cut to 5/8×24, including many .308 and 300 Blackout builds. As a traditional side-venting brake, it works to cut felt recoil and reduce muzzle rise between shots on calibers that hit noticeably harder than 5.56. It is built from steel with a corrosion-resistant QPQ melonite finish for long service life. It is a solid choice for shooters running a heavier-recoiling AR-pattern rifle who want faster, more controlled follow-up shots.
