Troy Rail Mounted Folding Battle Sight - A4 Front Use with all M4, M16A4, SR25 and AR10 Flat Top configured weapons. FBSA4F Front Picatinny rail mounted folding sight for M4/M16A4/SR25/AR10
Best front iron sight I've used so far. It's durable, well made and I really like the way HK style sight seem to naturally line up when you look through them. Wish the iron sights on the M4 where set up like this sight is. A little white out on the tip of the sight post adds contract and is a great way to make this sight even better
Durable, easy to install, and returns to zero. I especially like the HK style opposed to the M4 style because when looking at it through my aimpoint, it tends to center itself.
