Frequently Asked Questions

Which Gemtech suppressors is the QuickMount Flash Hider compatible with?

The Gemtech QuickMount Flash Hider is compatible with all Gemtech 5.56mm suppressors that use the QuickMount system, including the M4-96D, G5, G5-T, SHIELD, HVT-QM, QUICKSAND, and ONE models. It also works with Gemtech's .30 caliber QuickMount suppressors, making it a versatile host device for multiple cans in your collection.

Can I use this flash hider without a suppressor attached?

Absolutely. The Gemtech QuickMount Flash Hider functions as a fully capable standalone muzzle device when no suppressor is mounted. Its aggressive tine design effectively reduces muzzle flash, and the QuickMount lugs remain low-profile and out of the way during unsuppressed use. Many users run it full-time as a flash hider and simply attach their suppressor when needed.

What is the purpose of the included precision shim kit?

The precision mounting shim kit allows you to properly time (orient) the flash hider so the tines are correctly positioned relative to the bore when fully torqued onto the barrel. Correct timing ensures optimal flash suppression performance and proper alignment of the QuickMount lugs for suppressor attachment. Using the shims is highly recommended for best results and a secure, repeatable mount.
