The Midwest Industries Combat Rifle sight set brings modern advancements to their line of BUIS. This pair of folding sights are machined from 6061 aluminum and finished with a durable black coating to protect them from wear and weather. They feature a low-profile and snag-free design, so you only notice them when you need them. They feature a durable detent to secure them in the upright or down position during recoil but will collapse to prevent them from bending or breaking if impacted. The rear sight is windage adjustable and features an aperture for precise aiming.
