MBUS PRO® FLIP-UP SIGHT SET FOR AR-15

MBUS PRO® FLIP-UP SIGHT SET FOR AR-15 Reviews & Ratings

Made from case hardened steel with a corrosion resistant, melonite finish, these flip up sights fit all 1913 Picatinny rails. Both sights have positive detents to keep them secured at standard AR sight height when deployed, but low profile when stowed. Dual aperture rear sight features a tool-free windage adjustment and is only 3/8" above the rail when stowed.


Front sight has a finger adjustable elevation knob on the post, eliminating the need for any tools and sets 7/16" above the rail when stowed.


Narrow width of the front sight makes it compatible with most IR aiming laser and light installations.


SPECS
  • Steel, melonite finish, black.
  • Rear Sight – 2" (5cm) OAL, 1-7/16" (3.7cm) wide, 3/8" (1cm) above the rail when stowed. 1-7/8" (4.8cm) high deployed.
  • Front Sight – 1Ѕ" (3.8cm) OAL, 1ј" (3.2cm) wide, 7/16" (1.1cm) above the rail when stowed. 1-11/16" (4.3cm) high when deployed.

Excellent product
These Magpul sights are excellent. The front sight adjustment is a little stiff at first but if you don't have girlie hands it isn't bad. Plus it's most important they stay tight and gold adjustment. I'll buy again.

Great sights! Lay super flat.
These sights are perfect for a SBR build, as they are a little smaller than the typical sights, and they lay extremely flat. Great if you have flip up magnifiers that require clearance, or you

Excellent
The MBUS Pro sights are excellent. The only thing that was holding me back was the price. Normally the front is around $130 and the rear is around $80. This set was $150!! WELL worth the money!!
