Basic Information
The weapon is essentially a Belt Fed Caseless Medium to Heavy Machine gun that fires 7.62mm x 63mm (.30-06) Caseless rounds. The weapon exploits the use of a detachable barrel, and can interchange between two main barrels.
The first barrel is designed primarily for use by advancing Infantry. It consists of a heavy 18.5 inch polygonal five groove 1:10 inch (254mm) barrel. The second barrel, designed primarily for units in a fixed position and tanks, consists of a heavy 27.5 inch polygonal 5 groove 1:10 inch (254mm) barrel. The Primary difference between the two barrels is slightly improved accuracy for the second barrel, and greater long term performance of the second barrel, requiring fewer barrel changes and being capable of taking extended periods of fully automatic fire. This, besides the obvious 9 inch length difference and dramatic size difference of the thickness of each barrel.
The weapon of course fires caseless rounds with disintegrating belt links. The weapon can either be fed with either 100 round or 200 round fixed heavy plastic containers, or through an unattached source of some kind. The weapon exploits an interlocking 8 rotating bolt heavy firing mechanism, exploiting the weight and size of each bolt for reliable firing. The bolts must fit in and match perfectly with the chamber when firing, as to allow the caseless rounds high felt pressure to be mitigated. This is, however, is relatively easy to do and is actually achieved by a number of non-caseless weapons to date (including the G36 and HK416). The weapon, requiring impeccable timing, as well exploits the same star shaped mechanism in the AK-108 in a manner in which the spent gases power a counter mass, which essentially mitigates the primary felt recoil. In addition to the weight, the counter mass essentially reduces most of the recoil of the weapon, although it can cause reliability issues and must be monitored and actively checked every 5000 rounds or so.
To power the entire motion of both the rotating bolt and sliding counter mass, a large piston exploits the spent gases created by the round by using them to press down on a piston. The piston in turn powers a rod, the rod of which transfers the energy to the primary mechanical mechanisms of both the bolt, rotating mechanism, and sliding counter weight. The excess gases, rather than being sent straight back into the firing mechanism, instead work on the piston and are nearly harmlessly vented upwards. This gas, being vented upwards, in turn also helps deal with muzzle rise, although the muzzle rise is relatively low.
