The first 30 FC-15 carbine prototypes were delivered to the [[Lumenic Army]] in November of 2008 for preliminary testing. Later, at least 200 developmental prototypes were procured covering all four weapon system requirement; carbine, personal defense weapon, marksman rifle, and squad automatic weapon. Among the complaints during testing was that the battery life was too low for the weapon's powered sight system and some ergonomics issues. Two other key issues were reducing the weapon's weight and increasing the heat resistance of the hand guard, which would start to melt after firing too many rounds. The main testing was largely completed, and the Legion pushed for funding for a large field test. However, in 2009, the Chamber of Demagogues denied ₳26 million funding for 7,000 rifles to do a wide scale test fielding of the FC-15 in 2010, stating that the mney would be released and field tests could be conducted when the chief complaints of the initial testing round had been addressed. The weight of the FC-15 carbine was reduced from 3.4 kg (7.5 lb) to 2.8 kg (6.2 lb). | |||

Additionally, the FC-15FA lacked several key features that the Lumenic Army found desirable regarding the ML-95, notably fast barrel replacement capability, a high rate of fire, and the option for a belt-feed system. With the ML-89 already being phased out by a superior weapon to both it and the FC-15FA, the FC-15FA was dropped from the development cycle in 2009, and would not be included in the planned large troop trials slated for 2010. | |||

The ARO FC-15 is a modular weapons system developed and produced by Arsenale Reale e Ordinanza S.p.A of Luminerra for the Lumenic Legion to replace the FC-98 assault rifle.
History and development
The first 30 FC-15 carbine prototypes were delivered to the Lumenic Army in November of 2008 for preliminary testing. Later, at least 200 developmental prototypes were procured covering all four weapon system requirement; carbine, personal defense weapon, marksman rifle, and squad automatic weapon. Among the complaints during testing was that the battery life was too low for the weapon's powered sight system and some ergonomics issues. Two other key issues were reducing the weapon's weight and increasing the heat resistance of the hand guard, which would start to melt after firing too many rounds. The main testing was largely completed, and the Legion pushed for funding for a large field test. However, in 2009, the Chamber of Demagogues denied ₳26 million funding for 7,000 rifles to do a wide scale test fielding of the FC-15 in 2010, stating that the mney would be released and field tests could be conducted when the chief complaints of the initial testing round had been addressed. The weight of the FC-15 carbine was reduced from 3.4 kg (7.5 lb) to 2.8 kg (6.2 lb).
Although initially part of the original testing, the FC-15FA preformed poorly, outperforming the ML-89, but not offering any advantage over the existing ML-95 squad automatic weapon. Additionally, the FC-15FA lacked several key features that the Lumenic Army found desirable regarding the ML-95, notably fast barrel replacement capability, a high rate of fire, and the option for a belt-feed system. With the ML-89 already being phased out by a superior weapon to both it and the FC-15FA, the FC-15FA was dropped from the development cycle in 2009, and would not be included in the planned large troop trials slated for 2010.
Concurrently to the development and testing of the rifle, ARO, along with Ordigno Esplosivo S.p.A, was engaged in development of companion grenade launcher for the FC-15. This device, unlike the initial FC-15, was met with general interest from the Legion, as it was both backward computable with the FC-98, and could be used as a stand alone weapon system. The lanciatoregranate 15, or LG-15, received approval and funding from the Ministry of Defense in 2008
Funding for the M320 grenade launcher, which is a single-shot under-barrel grenade launcher similar to the M203 that was originally intended for the XM8, was approved. The launcher is actually heavier than the M203, but does offer some advantages. The XM320 was designed for use with the existing inventory of M16s and M4s and is also compatible with the XM8. It can also be used as a stand-alone weapon.
An electronic round counter was proposed for the FC-15. The system would have tracked the number of rounds fired and the date and time of each shot. The data would then be accessed wirelessly by a device like a PDA. Another benefit would be to monitor unauthorized weapon use or corroborate field reports. While this system was seen as beneficial by both ARO and the Lumenic Legion, it was ultimately dropped from the design in 2009.
Design
The materials used to build the FC-15 are almost entirely composites, with the notable exception of the cold-hammer-forged steel barrel. This has contributed greatly to the weapons lightweight construction.
The FC-98 carbine barrel is 368 mm (14.5 in) and the FC-15 barrel is 317 mm (12.5 in) but the rifles have the same overall length. Although a shorter barrel generally results in lower muzzle velocity, polygonal rifling techniques partially compensates for the loss of velocity from a shorter barrel.
The FC-15 also departs from the traditional rail Integration System found on the FC-98 rifles and other rifle designs from around the world. In its place is a proprietary system developed by ARO called the Punti di Attacco di Combattimento, or Combat Attachment Points, PAC for short. The benefit of the PAC system when compared to standard RIS attachments is the precision of the accessory's connection with the body of the weapon; accessories utilizing rails often need adjustment if they are removed and reattached. Additionally, most standard accessory functionality is built into the FC-15, as it contained an integrated reflex sight and laser illumination device. While the PAC system was not backwards compatible with existing RS mounted device, it was ancipated by ARO that accessories would be redesigned to utilize the new system. However, complaints regarding the battery life of the integrated optic, and regarding the lack of modularity and customization, spurred ARO to develop a version of the FC-15 with a traditional rail integration systems, primarily for use with special forces operators. The grenade mounting point remains unchanged, and continues to utilize the PAC mounting system.
Initial versions of the FC-15 included an integrated electronic non-magnified weapon sight which also contained a visible/IR laser. The only expectation to this, initially, was a 3.5x magnified sight for the FC-15TD designated marksman rifle. The purpose of the integrated sight/laser was to eliminate the weight and cost of requiring multiple accessories to be attached to the rifle via attachment points. The baseline FC-15 carbine can be compared to an FC-98 carbine with a host of previous-generation electronic add-ons, including optical and iron sights along with a laser aiming device. These comparisons showed that the rifle was heavier than the FC-15, in addition to being more cost effective and logistically sound, requiring fewer parts.
