Mission First  Tactical SCPM556 Standard Capacity Polymer Mag Review – “Conventional” Lightweight AR15 Build

Mission First  Tactical Standard Capacity Polymer Mag

The most needed accessory for the rifleman, the one thing that keeps the ammo aligned to placed in the chamber, the magazine. As mission First  Tactical names it the Standard Capacity Magazine, this standard, should squelch any misinterpretation of how many rounds the AR15 should hold.

MFT Standard Capacity Polymer Mag field use results

We have been using the MFT Standard Capacity Polymer magazines for field testing and shooting both rifles in the Lightweight AR Project. The ammo used was provided by several brands. The rifles are chambered in the .223 Wylde. So, both .223 Remington and 5.56×45 Nato have been used in a variety of bullet weight configurations. The magazines have not given us any issues in either of the Lightweight AR Project rifles, or any other AR15s that have been used with them along the way.

MFT Standard Capacity Polymer Mag fit and finish

The texture is even, showing good edges in between the textured and the ribbed areas, in which such transitions increase the grip from either a bare or gloved hand. The rough areas are not overly gritty that I would ever think it is rough to grip. I might be inclined to say that the texture could be a bit rougher to increase the traction with skin or gloves. The over molded ribs on the other hand do enhance the hold for both inserting or removing the magazine into the rifle.

The lips for the magazine hold the bullets in without problem and regardless of having 2 or 30 round in it. The spring tension always delivers the proper push on the follower and makes followup shots no problem. Magazines with weak springs will fail to have the second bullet ready for the BCG, and this has not been an issue in our testing.

The magazines are made from two halves and it is noticeable by the visual line that the welding leaves, but there is not a measurable way of quantifying, it is however felt if one drags a finger or fingernail over the line.

The magazines have a very positive hold once they are placed into the rifle’s receiver. I have not experienced any lost or released magazine through any of  the shooting of field use. The magazines have been durable enough and have not cracked or broken when dropped full, partially full, or empty from a standing shooting position. this might differ depending on the landing surface, our use was over loose gravel and dirt with some vegetation.

MFT Standard Capacity Polymer Mag disassembly

The bottom plate can easily be removed without the use of tools but does require two hands to accomplish. All it takes is pressing the bottom spring holder notches with 1 finger nail at each port and pushing the bottom plate forward. (I hope I don’t have to mention not to try this with ammo in the magazine, or the magazine inserted in a rifle.)

MFT Standard Capacity Polymer Mag final thoughts

I have been very satisfied and pleased to evaluate the magazines. These Standard Capacity Polymer Magazines performed without malfunction, regardless of variety of ammo used or rifle they were used in.

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.
