The C20 is a
semi-automatic rifle that uses 20-round
7.62×51mm NATO box magazines. A major part of its design philosophy was making sure that it was reliable in extreme conditions, such as those specified in the
NATO D/14 standards for safety, in which aspects of the weapon such as the
kinematics, safety features, recoil, and barrel strength are put under the most severe strain. During these tests, the C20 fired 8,000 rounds without any stoppages and achieved an accuracy of 0.66
MOA over 144 five round groups. The C20 barrel features 4 groove
rifling with a 1:254 mm (1 in 10 in)
twist rate. Colt Canada also advertises the weapon's versatility, offering features such as: • An optional
chrome-lined barrel •
Upper receiver integrated with a previous Colt Canada weapon, the
Modular Rail Rifle •
MIL-STD-1913 44 or 48 slot top rail with 0 MOA or 20 MOA integral incline •
M-LOK slots in the 3, 6 and 9 o’clock positions • Double-stage trigger • Adjustable buttstock == Users ==
