Reviews & Ratings for Breek Arms Plan B Sentinel Closed Flash Hider — 4 reviews — Page 1

Solid and to the point: the Breek Arms Plan B Sentinel is a semi-compact, well-made caged flash hider that’s perfect when you need real flash suppression without stretching your barrel — it’s machined from 4140 hardened steel, nitride finished, runs about 2.15" long and weighs roughly 1.8–2.2 oz depending on caliber, and it’s built to work with the Plan B/Atlas quick-mount system. The closed-tine/caged design does a good job breaking up and redirecting the muzzle signature (NVG-friendly), and it’s pin-and-weld ready if you’re tying it into a 14.5" build. Fit and finish feel like what you’d expect from Breek at this price — clean machining, solid threads and a proper peel washer in the box — In my opinion it looks and functions better than its modest price suggests. One caveat: the internal depth can protrude farther into certain low-profile mounts/suppressors than expected, so double-check clearances if you’re mating it to a specific can. All told, if you want a short, snag-resistant flash hider that plays nicely with Plan B accessories and actually tames signature in low light, the Sentinel is an easy, practical pick.
