In November 2013, Jesse James Firearms Unlimited unveiled its first two firearms, a 1911 pistol and AR-15 rifle. His first rifle-caliber suppressor was a basic reworking of an original Maxim design that he claimed could impossibly bend the laws of physics by offering a 78 dB rating at the muzzle, lower than even what the De Lisle carbine achieved in testing; although James was careful to note that it only achieved that number with subsonic ammunition that does not produce a sonic boom.
