Syrac Ordnance AR-15 A3 Flat-Top Upper Assembly 223 Wylde 1 in 8" Twist 16" Barrel CM Carbine Gas with 9" Midwest Industries Gen 2 SS-Series Free Float Handguard, Clamp On Gas Block, Flash Hider
The upper's unique 223 Wylde chamber has a throat length (leade) that's longer than a 223 Remington chamber, but tighter than the SAAMI specification for a 5.56x45mm NATO chamber. Its reliability with either type of ammunition and excellent accuracy potential make the 223 Wylde chambering "just right" for a multitude of roles, making it an equally good choice for use in competition, for hunting, or for defensive purposes. The upper's versatility is further increased via its clamp-on Syrac Ordnance adjustable gas block. This superb low profile block resides under the Gen 2 SS handguard and features a positive, detent-locking system to securely hold the adjustment screw in place once set to the desired gas flow, thus ensuring that the screw won't back out or shift positions during rapid strings of fire. The upper comes complete and ready to fire out of the box upon installation onto any standard AR-15 lower receiver.
