Background Information

As part of the mandate for the Conservative Party's election, the government has begun to pursue its development of a domestic armaments industry to eventually achieve self-sufficiency in the construction of arms for the Imperium Military. Following this, the government gave a mandate to the newly formed Imperium National Armaments Corporation (INAC), one of several State Corporations created as part of the parties election, to provide an indigenous Assault Rifle for the Imperium Infantry Forces to uphold or supercede the abilities of the current M16 Assault Rifle in military use.

INAC took the design and developed the INACAR-01. Initially critical of the weapon, the Imperium Ministry of Defence eventually agreed to procure the rifle for infantry use following decisions that the advantages in the design supercede the trade-offs.

Equal in length to the M16A2, the weapon maintains a shorter physical barrel than its American rival, but with length extended into the shell of the gun. Unlike the M16, the INACAR-01 utilises a Gas Piston mechanism rather than the more direct system of the M16, thereby reducing cleaning requirements and increasing barrel durability. Ministry of Defence field tests found each weapon to have an average barrel life of 15,000 rounds, compared to the 6-7,000 round life of the M16.

Although the INACAR-01 is slower in rate of fire, it makes up for this discrepancy in range and precision. Using the 7.62mm NATO cartridge rather than the 5.56mm cartridge, INAC designers decided to trade-off firing rate and full automatic stability for longer range fire and greater precision in semi-automatic fire. Due to the recoil problems with using 7.62mm ammunition in fully automatic operation during the early tests of the prototype, the production model of the INACAR-01 is not fitted with an automatic fire setting, and only utilises a single-shot and semi-automatic choice of operating speed.

The INACAR is physically bulkier than the M16, but at a relatively light weight due to Fibre-Reinforced Polymers utilised in the body construction. To reduce the physical number of parts, the piston cylinder, the barrel, and the rest of the internal spacing is effectively 'hollowed out' of a two-part FRP casing with both sides bolted together. The chambering handle is located on the left of the weapon, above the ejection port. The scope maintains a 1.5x Magnification Setting, and Night-Vision setting for low illumination firefights.

(OOC: I have tried to research this design to a suitable standard, but I am a complete novice with regards to weapons design. The gun itself is obviously a Warhammer 40K Lasgun, but I love the shape and therefore decided to build a projectile rifle that looks like it. The drawing of internal schematics is my own, copied onto the top of a model someone else drew. I would appreciate constructive criticism on the model.

OOC: 7.62x39mm is the Soviet round, not the NATO one. 7.62x51mm is the NATO round.

OOC:
9.8 inchs is stupidly short for a barrel length of a rifle, taking measurements from your rifle pic, it should be closer to 17.5" which would be pretty average for a 7.62mm NATO rifle coming inbetween the 18-21" barrels of the full rifles and the roughly 12-16" barrels of the carbines.
Appart from that and the issue of a totally ususitable picture it seems OK. If you must use the crappy 2nd/3rd edt lasgun then try to take advantage of its shape and sheer bulk, mainly big using the big underbarrel tube as a low capacity helical magazine, i'm not sure how well 7.62x51mm would work ina helical mag but it would ceretainly make the rifle more unique and take advtage of the lasgun's pointless bits n bobs.

(OOC: Okay, I'll adjust the barrel length, thankyou. :) As regard the unsuitability of the picture, I do appreciate that - I just really like the design of the weapon, and decided to write up a model as a projectile weapon, hence my drawing of the internal firing mechanisms within the weapon itself. But thankyou for the advice - I shall probably invent some future 'updated' models that take more advantage of the weapon's shape. At the moment however, I'm quite pleased that my very inexperienced designing of specs seems to be pretty much okay. :))
