·I'm building a flat-top and will need a rear BUIS. I'm totally undecided between the two. Anyone with more experience care to chime in?
ARMS #40L Flip Up Rear Sight - Low
- spring loaded with a quick release lever.
Two aperatures, one for 250-300m and one for 500-600m.

They both cost $118 + shipping.ARMS 40L-SP
Identical to ARMS 40L, but uses the same plane aperture system.
Allows operator to choose between large and small aperture without worrying about zeroing to different ranges. Small aperature can be removed.
