Mission First  Tactical FLIP UP sights Review – “Conventional” Lightweight AR15 Build

Mission First  Tactical Polymer Flip Up Front and Rear Sights

Although not the heaviest duty or unbreakable, these flip up sights serve the purpose of a secondary back up sight. The MFT Flip Up sights stay folded and tucked under a scope or can be used as co-witness with some of the minimal reflex sights or red dots.

These back up sights do contain the large and small aperture that help you focus on close or long range targets. There is, as expected windage adjusting for the rear sight and elevation adjustable for the front post. The standard tool and 1/4″ MOA per click of adjustment is for the front post, while the rear sight has what is described and infinite adjustability. I take that as a lack of clicks, and the use of a small Flathead screwdriver is needed for turning the adjusting screw.

The sights are trapped down by a sliding cover and they are spring loaded so they pop up and stay deployed as soon as the sliding cover is pulled back. The reverse motion is needed to drop the sights, light pressure is applied to lower them and then with a push of the slide, friction will keep them closed.

An unfortunate lapse of judgement from the review files

Not long after the rifle was assembled we took it to the range for initial testing. At a break in the action Jeff grabbed the rifle for a quick photo shoot on the back of the Project HMMWV Battlewagon.

Mere seconds before disaster…

As you can see, the rifle stayed balanced long enough to capture a rather nice image. Then, without warning, the rifle took a dive down 4 feet, landing upside down on hard gravel. The good news is that the Vortex PST scope (which is awesome) and the front MFT Sight were unscathed. I guess the unintended drop proves that the sights are durable, at least as much as we can tell after being dropped from the Battlewagon.

Mission First  Tactical Polymer Flip Up Sights performance

Adjusting the sights is easy and anyone with basic firearms training should have no trouble doing so. Windage adjustment for the rear peep-sight is easy. Not having clicks helps get a more precise final adjustment. Once your zero is set, I recommend that you use Kentucky windage rather than changing the zero for different distances for the sights. Our rifle has been set for quick transitions and the sight zeroed. So, that’s how it will be used.

The sights have the blend of metal parts and polymer which have been assembled properly and were easy to install on the AR15 upper receiver’s picatiny rail. I like the attention taken to the sights as they were shipped with shims that safeguard the polymer from braking if the screws are tightened without being installed.

Mission First  Tactical claims to be at the leading edge of composite products.  I would have a difficult time disputing that statement.

From my experience the Mission First Tactical Flip Up sights are durable and light.

Lightweight AR15 Review Project

With so many brands introducing light weight parts and rifles, we put together two AR15s that barely tip the scales. We call this series of reviews… the Lightweight AR Review Project.

The two rifles are:

  • “Conventional” Lightweight AR15 – mostly aluminum that has been aggressively lightened.
  • “Carbon fiber” Lightweight AR15 – combo of lightened aluminum and carbon fiber

This is our “Conventional” Lightweight Build

Each brand that sent parts for this build is featured in a separate article. This one is for Mission First  Tactical Battlelink stock.

Mission First  Tactical

We were introduced to Mission First  Tactical’s line of AR15 components and accessories at SHOT Show 2017. What caught my attention was a clever banner that said 30 rounds capacity is THE standard for  AR15 magazines. I could not agree more. Mission First  Tactical uses Polyamide materials to manufacture state of the art products to enhance the functionality and provide a weight reduction to the rifle. After contacting them during SHOT, they gladly answered our invitation to participate.
