Surefire Suppressor 338 Lapua

SGC ID:084871310437


SureFire Fast-Attach sound suppressors for rifles and carbines can be fitted to many military-type firearms by screwing the suppressor adapter onto the firearm&#39s existing muzzle threads. (Our adapters are required for attachment of all Fast-Attach suppressors)

For firearms lacking muzzle threads, or having muzzle threads of incompatible size, the muzzle must be threaded or and/or turned down so that it accepts the proper suppressor adapter.


For .338 Lapua Magnum caliber (8.6X70 mm) rifles and carbines. Adapters available for Acc. Int&#39l AWM, Sako TRG-42, Armalite AR-30, and other rifles threaded to accept a compatible Surefire adapter. Adapter required for attachment to all firearms.
