Let’s Dive into Magpul Industries MBUS Front Flip-Up Back Up Sight Gen 2

The Magpul Industries MBUS Front Flip-Up Back Up Sight Gen 2 is a staple in the AR-15 world. This front sight provides a reliable backup sighting system without breaking the bank. I remember when polymer sights were considered a joke, but Magpul changed that perception with their MBUS (Magpul Back-Up Sight) line.

I’m a firm believer in redundancy, especially when it comes to critical equipment. My red dot sight is fantastic, until the battery dies, or it gets damaged. Having a reliable backup sighting system like the MBUS Gen 2 front sight provides peace of mind.

Unboxing the MBUS Gen 2 front sight revealed a simple, lightweight, and seemingly durable polymer sight. The spring-loaded flip-up mechanism felt positive and secure, instilling confidence. It was surprisingly robust for its weight and price.

I considered other backup sights, like metal flip-up sights from Troy Industries or Midwest Industries. Ultimately, I chose the Magpul MBUS Gen 2 for its reputation for reliability, affordability, and minimal weight. It also co-witnesses perfectly with my red dot.

My first impression was positive; the MBUS Gen 2 front sight felt well-made and functional. I was eager to test its zero retention and durability on the range. It’s a simple piece of kit, but I had a feeling it would perform well.
