LMT Defense 3 Prong Flash Hider Restrictor Cap Features The LMT Defense 3 Prong Flash Hider Restrictor Cap is built specifically for 5.56mm rifles and threads onto a 1/2x28 muzzle the standard thread pattern found on most AR-15 pattern rifles. Its purpose is to further reduce visible flash signature which matters for shooters operating in low light where muzzle flash can momentarily impair vision or reveal a shooter s position. By restricting the escaping gas pattern the cap helps direct combustion byproducts away from the shooter s line of sight. This makes it a useful addition for anyone running a rifle in home defense duty or low-light training scenarios. Designed as an end cap rather than a standalone muzzle device the Restrictor Cap is meant to complement an existing setup adding flash control without requiring the shooter to replace their primary muzzle device. The compact low-profile design keeps the rifle s overall length and balance largely unaffected. Because it threads onto the common 1/2x28 pattern it fits a broad range of 5.56mm rifles without requiring a gunsmith for installation. The LMT Defense 3 Prong Flash Hider Restrictor Cap is a simple affordable way to dial in a rifle s flash performance for any lighting condition.
