Samson front and rear sight set - Samson Top Mounted Deployable Front and Rear Sight for AR-15

All quality BUIS are expensive and after much research I decided on these. They are taller than I expected but still fit under my Leupold scope. They installed easily on my RRA Predator Pursuit AR with a straight screwdriver and some lock tight. I only had to adjust the front sight pin up and was hitting a 3 inch target at 100 yards every time.I didn't have to adjust left or right. They flip up with a push of a button and stay up until you push it and manually fold them down. Very solid and I would recommend these to a friend.
Pros: Solid Construction, Easy to use
Cons: cost
