ARMS40L: A.R.M.S. #40L LOW
PROFILE FLIP UP REAR SIGHT - AR15 BUIS Rear Sight
ARMS #40L Spring Loaded Rear BUIS for the AR15/M16 flat top family of
rifles that is easily operated with bulky gloved hands. The A.R.M.S.® #40L
Low Profile Flip-up rear BUIS sight is designed to be a cowitness backup
sight that can deploy in a split second when optics have failed. With a
miniaturized windage knob and low mounting height, this ARMS BUIS is ideal for
mounting behind or underneath riflescopes or the EOTech HWS and other red-dot
sights. The A.R.M.S. sight is held in the locked down
position by a quick release lever, that can be deployed with the flip of your
finger. Initial elevation zero is acquired by adjusting the standard M16A2/M4 front sight
post.
The newly designed 250-300 meter Dual Leaf Aperture and smaller miniature
windage dial design allow the A.R.M.S.
Low Profile #40L spring loaded flip-up rear BUIS sight to sit nearly flush with
the top rail when mounted behind an A.R.M.S. base riser.
