This firearm had original accessories of a hard plastic case, a nylon case with extra magazine pouches, a forward handle, a flash suppressor and recoil compensator as well as a barrel extension.

For situations where more firepower was necessary, the concealable pistol was modified to accept a barrel extension with hand-grip and silencer, a Phantom Bushnell pistol scope, an extended magazine and a collapsible shoulder stock.

As the bolt carrier moves toward the butt of the gun, the bolt cam pin, riding in a slot on the bolt carrier, forces the bolt to rotate and thus unlocks it from the barrel extension.
44.
The bolt itself features 4 radial locking lugs that engage the barrel extension and its rotation is controlled by a pin on the bolt body, which rides inside a camming guide machined into the bolt carrier.
45.
As the assembly of bolt, barrel and barrel extension recoiled to the rear of the gun upon firing, the locking block was drawn out of engagement by a cam in the bottom of the gun's receiver.
46.
A portion of this force is transmitted through the rollers projecting from the bolt head, which are cammed inward against the inclined flanks of the locking recesses in the barrel extension and to the angled shoulders of the locking piece.
47.
The roller-locked recoil operation functions as follows : two cylindrical rollers, positioned in tracks on the bolt head, are pushed outwards into matching tracks in the barrel extension by the striker sleeve and lock the bolt in place against the breech.
48.
Since the 9?9mm Parabellum cartridge is relatively low powered, the bolt does not have an anti-bounce device like the G3, but instead the bolt carrier contains tungsten granules that prevent the bolt group from bouncing back after impacting the barrel extension.
49.
The barrel and barrel extension continue to move rearward to a point slightly exceeding the combined overall length of the cartridge case and projectile ( the long portion of the recoil system, responsible for the weapon's low rate of fire ).
50.
The cartridge case design was finalized based on discussions with Tony Rumore at Tromix suggesting a lengthened . 50 AE case would work well in the magazines as well as be the largest diameter case to be able to feed through the barrel extension.
