Requires a compatible SilencerCo ASR muzzle device for quick attach/detach suppressor mounting.
The SilencerCo AC824 Harvester Big Bore ASR Mount is a Bravo-pattern ASR suppressor adapter for compatible SilencerCo suppressors. It allows compatible suppressors to mount over SilencerCo ASR muzzle brakes, ASR flash hiders, ASR closed-tine flash hiders, and compatible ASR muzzle devices.
SilencerCo’s ASR / Active Spring Retention system is a quick attach/detach rifle suppressor mounting system. The ASR mount threads into the rear of a compatible suppressor and locks over an ASR muzzle device, giving the user a repeatable mounting interface for supported rifle hosts.
Harvester Big Bore / Bravo ASR Mount: The AC824 mount is commonly listed for the Harvester Big Bore, Omega 300, and Hybrid suppressor families. SilencerCo’s current Bravo accessory listings identify the AC824 as the Bravo ASR Mount, so this product should be treated as a Bravo/Harvester Big Bore ASR mount, not as an Alpha direct-thread adapter.
ASR Muzzle Device Required: This mount is one side of the ASR system. The host firearm must be equipped with a compatible SilencerCo ASR muzzle brake, ASR flash hider, ASR closed-tine flash hider, or other approved ASR muzzle device in the correct thread pitch and bore size for the firearm and caliber being used.
SKU Correction Note: The old product URL text says “alpha direct thread mount 1/2-28,” but the product code AC824 identifies this item as the SilencerCo Harvester Big Bore / Bravo ASR Mount. The Alpha Direct Thread Mount 1/2x28 SKU is a different product.
Important Fitment Note: Always confirm suppressor model compatibility, Bravo/Harvester mount interface, ASR muzzle device compatibility, barrel thread pitch, muzzle device bore size, caliber rating, host firearm, shoulder geometry, torque requirements, and suppressor alignment before installation or live fire.
