Troy Folding Battle Sight- Rear, FBS-R

The Troy Folding Battle Sights have set a World Standard for design and quality by which all other Back Up Iron Sights are judged. They feature a hand-adjustable windage wheel and a new Dual Aperture. They are easily installed and position the apertures at the exact same height as the factory sights, with no levers or springs to fumble with, deployment of the sight under stress is easy. The robust stainless steel cross locking system ensures your sights will remain up and zeroed in the most extreme combat conditions.

To fold, simply press the release button located on the left side of the sight. All Troy Sights feature a zero-canting attachment system for use on all military and aftermarket receivers. No tools are required for adjustment. Each click equals .50 MOA of adjustment. The FBS-R sight has a Low .472" profile when folded, so you won't have any issues fitting it under optics.

These sights are rugged, snag free, and have a positive lock for accuracy and reliability. They are designed for instant deployment without levers or springs and are engineered to fit a variety of weapons such as the M-4, M-16, AR-10, and SR-25. Blackened Stainless Steel and MIL-SPEC Type III Hard Coated T6 Aircraft Aluminum construction.

Great choice April 3, 2015
Reviewer: Miles McClintock from Olympia, WA United States  
This is the second Troy BUS I've purchased. Quality machining and finish. I run a scope most times, but pull it off to shoot with the iron sites and it's dead zero. You could save a few bucks with others, but you'll never be satisfied. Buy this product!

Excellent Sight February 12, 2014
Reviewer: Nolan19 from Clinton, IN United States  
The Troy battle sights are, in my opinion, the best back up sights you can buy. They are very durable and can withstand a lot of abuse. They fold down really low and when flipped up they lock up very solid. I highly recommend these sights!

Troy folding sights= standard for BUIS April 28, 2013
Reviewer: malac gilkey from tacoma, WA United States  
I think the title says it all, outside of larue, its hard for me to find any product that this company makes that isn't stellar.  The Buis go above and beyond, very low profile, easy to use and holds a zero very well. These are my 2nd set from Troy.

Product faulty -- but SKD awesome as always March 12, 2013
Reviewer: John Sturm from Kettering, Ohio United States  
I have already talked to you guys about this, but the Troy rear sight is extremely wobbly in the up position.  It tilts side to side, and front and back with slight pressure. This is my 5th Troy sight and the only one this loose.  I have another rear that moves slightly, but it springs back to the normal position so there's no issue with POI shift.  This one will stick in multiple positions each time it moves and can be as much as 1-2 clicks if I was adjusting windage and 2-4 notches if I was changing the elevation on the front sight post.  You guys have already told me I am welcome to send it back, but I believe I purchased your last one in Tan, and am worried about waiting on a backorder.  I have contacted Troy to try to get an exchange, and they have been freaking awful.  I have filled out online contact forms, requesting to be contacted, made multiple phone calls, and finally just got a response (5 days later) in their industry forum on ARFCOM.  Your service has always been great.
