FR-27 Sanction Flechette Rifle (DXMD)

The FR-27 S.F.W., Flechette Ordnance is a weapon in Deus Ex: Mankind Divided.

Overview
The FR-27 S.F.W. returns from Deus Ex: Human Revolution with some slight alterations, featuring similar performance and versatility overall, but can be further customized with new proprietary attachments.

It is a highly mobile and dependable main arm for the aggressive player, dealing moderate damage at a rapid pace at the cost of relatively modest recoil. It is compatible with nearly every form of attachment the player may come across on the field that can be swapped in and out on the fly, making it a jack-of-all-trades combat firearm.

Again, the FR-27 returns as a very common firearm, being favored by almost every faction in the game. Ammo is not a particularly big concern given the ridiculous ubiquity of the FR-27, and ammunition packs for it are both common and very cheap to buy in shops. When loaded with the slightly-rarer Armor Piercing rounds, the FR-27 receives a big damage boost, making it more lethal during a shootout.

It should be noted, however, that due to the same ubiquity mentioned above, the Combat Rifle is also the most common weapon fielded against the player by enemies, though due to their weapons being largely inferior to the player's upgrade-wise, they'll occasionally have to pause to reload, giving one ample time to retaliate.

Elite Edition Combat Rifle

 * Included as part of the Enforcer Pack DLC, available as a free download.
 * Limited-edition burst-firing variant with slightly worse handling.
 * For some reason, upgrading the rate of fire will also further lower recoil.

Côte d'Azur S.O.W.

 * Found inside a weapon case in the Tarvos Security Services corporate vault underneath the Palisade Bank parking lot. The keycard for this vault can be obtained from the basement of Sobchak Security.
 * Special-ops anti-mech variant that fires only EMP rounds. Features an integral suppressor, a blue holosight, and a large magazine capacity.
 * This rifle inflicts non-lethal damage, and is the only weapon so far encountered with a raw damage bonus (as opposed to EMP 'stun' field inherent to all other EMP ammos and guns) to augs and robots. It takes about 5 headshots from this rifle to non-lethally down an ARC elite - same with shadow ops later in the game.
 * The Côte d'Azur may be traded for one of Nada Birak's special stocks.

Trivia

 * The FR-27 in Human Revolution was chambered in its proprietary .303 caliber discarding sabot flechettes, but has been standardized to use 5.56x45mm NATO rounds by the time of Mankind Divided as described in the inventory. It was reclassified in-universe as a Sanctioned Flechette Weapon instead of Rifle, due to its smoothbore barrel not having any rifling, though for gameplay purposes it is still considered as such.
 * The FR27s carried by enemies and various other NPCs do not have ironsights.
 * The FR-27's concept art featured in Deus Ex: Mankind Divided Mini-artbook depicts a few changes to the rifle visually, namely an altered foregrip and carry handle. While the weapon in the final build remained mostly unchanged from the previous game, the new design did in fact live on in the form of the Côte d'Azur unique variant.
 * The new carry handle design was also incorporated into the arm-mounted machinegun of enemy EXO-suits.
 * The Côte d'Azur ("Blue Coast"; literally: Coast of Azure in English) variant was named after the, the Mediterranean coastline of the southeast corner of France.
 * Despite the Côte d'Azur's carry handle featuring an integral smart targeting system, it behaves much like any other variant of the FR-27 during gameplay.
 * The Côte d'Azur is described as a burst-firing weapon on the official website and in the inventory, despite operating in full-auto during gameplay.
