A.R.M.S.® #40™L Low Profile Rear Sight
Selected as the best and was awarded a contract from Crane NSWC for use by U.S. Spec. Forces.
The #40™L has all the features of our excellent 40A2 sight, but has a lower profile, allowing more clearance for mounting optics to your flat-top receiver and allows lower mounting, miniaturized windage knob with .75 MOA adjustment and a very new and unique dual aperature. (Go to #40L-P for .50 MOA.) Folded height is only .610″. US Pat. 5533292,7356962,D526380
