On December 8, 2010, Adcor announced production of the A-556 rifle to the civilian market. On June 27, 2011, it was announced that the improved A-556 Elite variant would be available for sale to the public. In June 2012, a soldier was seen in Afghanistan with a A-556 upper receiver with a 10.5 inch barrel on an M4 lower receiver. [4]
Arguably, the criticisms about range, accuracy, and lethality are related to the change in barrel length and twist between the M16 and M4. The earlier 5.56 rounds (the original M193) were optimized for a 20-inch (51 cm) barrel with a 1:12 twist. In 1980 STANAG 4172 defined the 5.56×45mm NATO chambering and its accompanying 1:7 twist rifling. [38]
The Armada is a select-fire rifle composed of two receivers (upper and lower) manufactured in forged aluminum, uses a 22 in (560 mm) barrel with a 1:9 right-hand twist (able to stabilize both M193 "Ball" and SS109/M855 variants of the 5.56mm cartridge), Norinco CQ-style plastic parts (grip, stock, handguard), flip-up rear sight adjustable for ...

[9] [10] The most common model is the 635, the latest version of which are simply marked SMG 9mm NATO. [11]
The M110A2 is shorter than the original M110 and lighter as well at 10.5 lb (4.8 kg), which is comparable to the M110A1 SDMR's weight of 10.9 lb (4.9 kg) with no attachments save an unloaded magazine. The decreased overall length does not come at the cost of barrel length as the M110A2 still has a 20 in (510 mm) barrel. [2]
All versions are equipped with the 4.25-inch (108 mm) long moderator. [4] The XM177 uses a unique flash suppressor sometimes called a flash or sound moderator for its 10-inch (250 mm) barrel. This device is 4.2 inches (110 mm) long and was designed primarily as a counterbalance measure as the shorter barrel makes the weapon unwieldy. [5]
