    A.R.M.S. #40L Low Profile Flip Flip Up Rear Sight

    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.

    Only weighs 1.7 oz

    I have a arms 40l rear sight mounted on my other AR. It is a good back up sight. It is similar to the rear sight of the A2, minus the elevation, with distance flip-up view apertures. I'd regard that as a significant upgrade. It's practical, functional, well designed, and it's good.

    Everything I was looking for in a flip rear AR sight. Took me a second to figure out install since you have to slide it along the rail to install.

    This arms 40l rear sight is made from quality materials and workmanship here in the USA. It was a precision fit, and packaged with pride too. This is the only low profile flip-up rear sight to have if you are a competitive shooter and enjoy fine quality in your equipment.

    I have these AR BUIS on three of my duty weapons. They are precise, durable, and innovative. The ARMS flip up rear sight are the perfect height for co-witnessing with your optics. They provide precise enough sight picture for tight groups at the range, yet allow fast transition at close range when necessary. I would never head into a Hot Zone without them.

    Installed these AR Sights on a Del-Ton Dissipater HB upper; co-witnessed with an EOTech 512. No adjustments needed, was dead-on at 100 yards. This is the second one of these I've purchased for personal use, and it's the one flip-up rear sight we used to recommend when I worked at a commercial shooting range/gun retailer. Yeah - it's a little bit pricey, but it's packed with features, it's rugged and reliable. This is the one to get - why not start with the one you'll wind up with?

    I already own one of these ARMS #40L Flip Up Rear AR Sight and plan to get another one for my other ar. ARMS make a quality AR sight with a low profile so I can leave my red dot mounted or see-through without removing it. I quickly flip us too. I didn't need much adjustment. This Rear sight lined up great with my yhm front flip AR sight at 50 yds and maintained accuracy with the same plane peep sights.
