Description
The MP7 has one of those muzzle thread patterns that makes accessory shopping a headache, and M11.5×1 options are thin on the ground. KGM Technologies solved that with this quick detach flash hider, purpose-built to thread onto the HK MP7 and serve as the mount for their R556, R556A1, R556A2, R30A1, and R30A2 suppressors. Instead of hunting for adapters and hoping everything stacks up straight, you get a single dedicated muzzle device that was designed for this platform from the start.
How the KGM QD Flash Hider Locks Up
The mounting system is where this piece earns its keep. A taper mounting surface centers the suppressor and wedges it tight every time you spin it on, while a ratcheting secondary retention system backs that up so the can stays put through hard use. That combination gives you the two things people care about most in a QD mount: the suppressor goes on fast, and it comes back to the same place shot after shot. Point of impact shift between mounting cycles stays predictable, which matters when you zero with the can on.
Built From Chromoly, Finished in Nitride
KGM machines this flash hider from heat-treated chromoly steel and treats it with their OXyN gas nitride finish, so it shrugs off heat, carbon, and weather without fuss. Run it bare and the birdcage design does its usual work of taming muzzle flash on the MP7's short barrel, which throws a fair amount of fire on its own. Run it as a mount and it disappears under the suppressor doing its job quietly.
A Clean Answer for MP7 Suppressor Mounting
If you already own or plan to pick up one of KGM's R556 or R30 series cans, this is the piece that ties your MP7 into that system without any guesswork. One muzzle device, one suppressor line, everything designed to work together. That is about as simple as suppressor mounting gets on a platform this particular about its threads.

Frequently Asked Questions
Which suppressors does the KGM MP7 quick detach flash hider work with?
This flash hider serves as the QD mount for KGM's R556, R556A1, R556A2, R30A1, and R30A2 suppressors. It is part of KGM's quick detach mounting system, so it is not designed to interface with other brands' cans. If you are running one of those KGM suppressors, this is the piece that puts it on your MP7.
Will this fit my HK MP7's factory muzzle threads?
Yes, it is cut for the M11.5×1 metric thread pitch found on the HK MP7. That is an uncommon pattern, and this device was made specifically for it, so no adapters or thread converters are needed. Just remove your factory muzzle device and thread this one on.
Does the suppressor hold zero when I take it on and off this mount?
That is the whole point of the design. The taper mounting surface centers and tensions the suppressor the same way every time, and the ratcheting secondary retention system keeps it from backing off under fire. Together they give you repeatable lockup, so point of impact shift between mounting cycles stays minimal and consistent.
Can I run the KGM QD flash hider without a suppressor attached?
Absolutely. It functions as a standard birdcage-style flash hider on its own, which helps tame the flash signature from the MP7's short barrel. The heat-treated chromoly steel and nitride finish hold up fine to regular unsuppressed shooting.
