CYP-556

The CYP-556 is a modular assault rifle manufactured by Cypher Precision as a means to provide a highly accurate 5.56mm rifle, without excessive length and size. The shares lower receiver, magazine, receiver extension, grip, trigger assembly and stock with normal AR556 rifles, like the MK16 and MK4 carbine, leading to a level of parts commonality, weapon familiarity and relative affordable cost. The uses a short-stroke piston design from the MK36 rifle family, rather than the standard direct gas impingement system used by the numerous AR556 rifles, which prevents carbon build up inside the bolt carrier to avoid weapon failure and increase reliability and lifespan of the weapon.
== Design ==
The CYP-556 uses a short-stroke piston design from the MK36 rifle family, rather than the standard direct gas impingement system used by the numerous AR556 rifles, which prevents carbon build up inside the bolt carrier to avoid weapon failure and increase reliability and lifespan of the weapon. Because it utilizes the AR556 platform, it can share the upper and lower receivers of other similar weapons; Sharing the same magazines and calibers respectively. 
The reduction in heat and fouling of the bolt carrier group increases the reliability of the weapon and extends the interval between stoppages. During factory tests the fired 410,000 rounds in full-auto without malfunctioning. The CYP-556’s piston system was originally self-regulating in theory, but in the default position tends to give increased recoil over an adjustable gas system. A user adjustable gas regulator was added in later variants. 
The CYP-556's barrel is cold hammer-forged with a 350,000-round service life and features a 12 grooves 178 mm (7 in) right hand twist. The cold hammer-forging process provides a stronger barrel for greater safety in case of an obstructed bore or for extended firing sessions. Modifications for an over-the-beach (OTB) capability such as drainage holes in the bolt carrier and buffer system are available to let the CYP-556 fire safely as quickly as possible after being submerged in liquids like water.
The is equipped with a proprietary accessory rail forearm with STD-785 rails on all four sides. This lets most current accessories for MK4/MK16-type weapons fit the CYP-556. The FFB 12" can be installed and removed without tools by using the bolt locking lug as the screwdriver. The RIS handguard (FFB 12") is free-floating and does not contact the barrel, improving accuracy. It comes with factory standard Cypher Precision skeletonized buttstock, that is made for easier concealment and transport, while providing higher mobility at the cost of lesser stability compared to a fixed stock.
