A.R.M.S. #40-L "low profile" Flip-up Rear Sight (BUIS)

US Army and NWC Crane (US Navy) have used this sight on M4 and 416 special operation rifles

NSN 1005-01-575-3508

A modification the the #40 rear sight first fieled on the MK12 Mod0 SPR.  The #40 size worked well with the additional size of the Swan Sleve rail.  The request came in for a back-up rear sight as durable as the #40, but with a lower profile to be mounted on standard flattop rails on the M4A1 and the H&K 416 carbines.

The #40™L has all the features of the #40 A2 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. Folded height is only .610″.
