KGM Suppressors
KGM Suppressors is a suppressor manufacturer, and Impact Guns carries their muzzle-device lineup — the flash hiders, muzzle brakes, and thread adapters built around KGM's quick-detach and direct-thread suppressor mounting systems. Whether you already run a KGM can or just want a well-made muzzle device on a standalone build, these parts cover 1/2x28, 5/8x24, 3/4x24, and 1.375x24 thread patterns across AR-15, AR-10/SR25, and SMG9 platforms.

Quick-Detach vs. Direct-Thread: Which KGM System Do You Need?
KGM's quick-detach (QD) flash hiders and adapters let a suppressor lock onto the muzzle device without re-threading, ideal for shooters who move a can between multiple rifles. Direct-thread adapters, by contrast, thread the suppressor straight onto the barrel — simpler and often more affordable, but slower to swap between guns. Most of KGM's device lineup is available in both mounting styles across the same thread patterns.
R50T Taper Muzzle Brakes
The R50T is KGM's taper muzzle brake, built in black nitride steel and offered in 1/2x28, 5/8x24, and 3/4x24 thread patterns to cover 5.56/.223, most .30-caliber, and larger-bore rifles. It functions as a standalone recoil-reducing brake or as the mounting point for a QD suppressor adapter.
Quick-Detach Flash Hiders and Adapters
KGM's QD flash hiders are black nitride steel, available in 1/2x28 and 5/8x24 threading, and pair with KGM's QD suppressor adapters — including a 1.375x24 adapter sized for larger suppressor mounting systems.
Thread Pattern Guide: 1/2x28, 5/8x24, 3/4x24, and 1.375x24
1/2x28 is the standard thread pattern for 5.56/.223 barrels, while 5/8x24 covers most .30-caliber rifles. 3/4x24 is used on the SR25/AR-10 platform, and KGM's SMG9 direct-thread adapter is sized specifically for 9mm SMG-pattern barrels rather than standard AR threading. Confirm your barrel's thread pattern before ordering any muzzle device.
Frequently Asked Questions: KGM Suppressors
Does Impact Guns sell KGM suppressor cans?
Our current KGM inventory is muzzle devices — flash hiders, muzzle brakes, and thread adapters built for KGM's mounting systems, not the suppressors themselves.
What's the difference between a direct-thread and quick-detach adapter?
Direct-thread adapters thread the suppressor straight onto the barrel. Quick-detach adapters let the suppressor lock and release without re-threading, making it faster to move between rifles.
What thread pattern does my rifle use?
Most 5.56/.223 rifles use 1/2x28, most .30-caliber rifles use 5/8x24, and the SR25/AR-10 platform typically uses 3/4x24. Check your barrel's markings to confirm.
