Description
the G8 advanced combat rifle. (MK II variant). Currently the standard issue rifle for all Primus expeditionary forces, however it should be noted that G8 rifles are not necessary standard, over 300 variants of the rifle exist, most are variable due to the vastly different morphology of the recruits (e.g bigger hands are found on recruits from the British colony of Loch Goyle). The only standard is the ammunition fired (4.6x30mm caseless) and the integrated under slung "spit valve" air compressor.Initially design to prevent barrel fouling due to the immense pressures presented with caseless ammunition the "spit valve" siphons off gas from the barrel and stores it. By pressing the second trigger the user can release all the stored gas in one quick high pressure blast. Previous combat experience has found this pressure blast to be extremely useful for deflecting thrown grenades and knocking foes off their feet.

What kind of insane high explosive caseless rounds does this take that it needs half an OS strapped to the barrel?

The sighting system is sort of a 'smart reflex sight' allowing the users to use the (removable) sighting module for use as a reflector sight, an adjustable telescopic sight and a laser designator in one package. The sight also compensates for parallax issues and ballistic elevation on the fly. Finally the intelligent sight can 'mark' enemy units in its vision; relaying their positions and to nearby friendly infantry.

Not what I was talking about. The insane, overcomplex additional gas system duct taped to the barrel to counteract the +P++ overpressure round

Ah the gas system contains a large internal gas cylinder that stores excess gas as it flows down the barrel; allowing recoil, muzzle flash and wear to the barrel to be controlled to reasonable levels; while allowing some of the excess gas to be stored for future use.
As you may know +P+ ammunition and gas propelled projectiles in general 'waste' a significant amount of their energy as the bullet typically reaches a point where the maximum amount of possible energy transfer has been reached; at which point the the gas moving through the barrel only works to wear down the barrel, distribute waste heat and produce muzzle flash as opposed to accelerating the projectile ([link] .
Notice on this graph how the velocity begins to flat-line near its 20 inch journey; as such this isn't really an issue with most firearms as nitrocellulose based gunpowder's doesn't produce pressures high enough to warrant this to a major issue in most high velocity weapons. If we came up with a significantly more potent powder however you might see that projectile reaches terminal velocity by the time it has traveled 2/3rds of the barrel length (as I have imagined here). While some might argue this as an opportunity to shorten the barrel; I have opted to create a siphoning system that would reduce thermal expansion of the barrel (thus increasing operation lifetime), minimize muzzle flash, noise , recoil and all those negatives associated with high muzzle pressure.
That and you can use a powerful compression blast for breaching doors, knocking people over and stuff!

So it's extra weight without any practical application, got it.

I suppose minimal application
