Magpul MBUS 3 Sight – Rear

Overview These Magpul BackUp Sights (MBUS 3) take the affordability of the original MBUS sights and the low profile of the MBUS Pros and combine them to create the optimal balance between cost, weight, and profile. Their impact-resistant polymer construction keeps weight to a minimum while being durable enough to withstand abuse, and the toolless adjustments make zeroing quick and easy. If you want a folding front sight to match, we carry the MBUS 3 folding front sight as well. Or, if you want to run a fixed front sight, this rear sight will pair perfectly with the PRI or Scalarworks fixed front sights we offer. What’s Included 1x Magpul MBUS 3 rear iron sight We include an 8.5″ x 11″ rifle zero target with every rifle optic. We recommend a 50/200 meter zero for most 5.56 rifles.
