The FBS/RBS are an advanced, dual aperture, durable and low-profile auxiliary sights. They are readily mounted on any 1913 Picatinny rail, making it ideal for use on M4 / AR-15 / M-16 platforms and on the FAB Defense K.P.O.S.. Made of extremely durable high-grade polymer and metal, the sights features a low folded profile which is smooth and inconspicuous, and willnot snag on hear, webbing, or brush. The instant spring-lockable deployment mechanism will not slip, brake or deform. No tools needed for easy, repaid windage adjustments, with positive detent locking.

Oregon residents: If you are making a firearm purchase online from us, please understand, you are more than likely going to go in the FICS background check line of over 37,000. This means, that there's a good chance you'll still be in line on the 18th of December and are at the mercy of what the Judge in Harney County decides. At the point, there's a chance you'll have to get a permit-to-purchase said firearm. There will be no refunds for people that go in line and have to wait. Purchase at your own risk. That being said, we will continue to fulfil orders as they come in. Thank you for your patience! ~ Fifty1Fifty Tactical, LLC
