Magpul MBUS Sight, Front

The MBUS is a low-cost, folding back-up sight. The front sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15 / M16 platform.

Elevation adjustment

One click is a quarter (1/4) of a turn and your setting is retained by a detent. The effect of one click is roughly as follows:

• 1.6 MOA (48 mm / 100 m or 1.68" / 100 yd) with the sight radius of a 14.5" carbine
• 1.2 MOA (35 mm / 100 m or 1.26" / 100 yd) with the sight radius of a 20" rifle

The included leaflet says the adjustment range is fine for rifles but you could run into issues trying to zero a pistol-caliber carbine to longer distances due to the snowball-like trajectory. Savvy in trigonometry and ballistics as we are, we think you can overcome this by mounting the front and rear sights closer to each other. It's not like your PCC is very accurate and frankly, you're probably no marksman, either.

An elevation adjustment tool is included, but most aftermarket A2 front sight adjustment tools may be used as well.
