SPIKE'S Rear FLDNG Micro Sights G2

These sights are really the best folding BUS out there in terms of accuracy, durability, and low profile.

Good

These are really well designed and manufactured. I really like the fact that the rear sight has a sliding aperture for your choice of small or large peep holes. The front sight has a very precise needle point, and they say that the assembly is machined from billet steel as is the rear sight. Overall, this is a very high quality BUIS set. They are more expensive than some sets out there, but are high quality and highly recommended.
