About
Weapon from the "C.M.O.S" Universe. The LM-12B Tactical Assault Rifle. A Standard issue of the UA Army after the war.

The LM-12 is the standard Weapon used by the UA Army since the end of Global "Terror War". The original design, based on the bullpup configuration, is innovated by reowned firearms designer Nikolai Korzhukov. The LM-12's design managed to keep most of the operating functions similar to the war-proven AR15 and M16 rifles which most UA soldiers are familiar with.

It was further enhanced and modified by it's mass manufacturer, United Arms Agency Inc, to cater for both advanced military and civilian needs.

LM-12 features the NATO k.V. box magazine that is known for is versatility. It's rotating buldge tip enables the magazine to be attached to the weapon at any angle, reducing reloading times and magazine/ammunition damage/jamming during the heat of the battle. Due to the unique design, the k.V. box magazine is also capable of holding up to 50 rounds of standard NATO 5.56mm ammunition. Currently, Magazines payloads are available in 50 rounds, 40 rounds and 25 rounds for civilian use.

The LM-12 is compatibility with plug-in I.O.N. booster adapters for increased rate of fire and range without replacing a delicated barrel or bolt carrier assembly. However the barrel's heating threshold will exceed after 3 full Magazine of continuous firing and the weapon's thermo fail-safe mechanism will lock the trigger until the barrel cools down below threshold. The mechanism can, however, be overwritten with a add-on module.

The LM-12 is also fully ambidextrous with no external parts swapping needed. The weapon can be easily switched by re-assembling the weapon and switching the positions of it's internal components

The LM-12 "B" variant includes an integrated Picatinny rails with P.R.I.C.K interfaces ports for tactical flexibility with the latest weapons attachments.

eXpressions
Designed this weapon during NS times in 1999 or 2000. Was inspired by the SAR-21 and AUG-77 then. This weapon was the main weapon used the male protagonist in my "C.M.O.S." Series.

Since then, firearms evolve a little to accomodate customized add-ons, so I updated my weapon to go with the trend and added a little FN F2000 elements to it. Quite happy with the outcome.
