First Look: Magpul MP BSL Arm Brace for the HK94/MP5

posted on June 7, 2021

The Heckler & Koch MP5 is one of history's most iconic firearms, and it has a well-deserved reputation for packing an accurate, controllable punch in a compact, reliable package. Used by organizations all over the world, it’s a go-to gun for some of the most elite units on the planet. A very similar gun, the HK94, is based on the same platform in the same caliber but has a longer, 16-inch barrel versus the MP5’s 8.9 inch barrel length.   

Now Magpul is launching the new MP BSL Arm Brace for the HK94/MP5, available exclusively online at The MP BSL Arm Brace is a lightweight, collapsible arm brace that aids the single-handed use of HK94 or MP5-pattern pistols, while still maintaining the iconic aesthetic of the firearm. The high-strength polymer and rugged metal construction of the brace combine with  a tool-less adjustment system that makes it easier to deploy and collapse the brace. The integrated QD sling attachment and ample surface area for lateral forearm contact dramatically increase stability while firing. An M-Lok slot is also included on the brace for other sling mounting options.

What is the Greatest Defensive Skill?

You can say what you want to about your favorite defensive school or those advanced-fighting techniques you learned, but the greatest defensive skill that a person can develop is simply awareness.
