Colt Canada (Booth 1029) has introduced a family of infantry weapons that offers lighter weight and better performance. The new Modular Rail Rifle (MRR) is based on the C8 carbine in 5.56mm calibre, but offers a new means of mounting accessories.
Instead of featuring mounting rails along the sides and underneath the barrel, the MRR family has a slotted system. The Magpul M-LOK rail attachment system allows accessories to be placed as desired, or even sections of standard rail, without the penalty of carrying redundant sections of rail.
Overall the result is to reduce the weight of the rifle by around 0.75 pounds. With the weight reduction being mostly made at the front of the rifle, the effect is to make it quicker to raise, and easier to swing – enhancing response times in combat situations.
Four barrel lengths are offered for the 5.56mm MRR: 11.6, 14.5, 15.7 and 18in. The 18in version is also offered in a non-chromed version for DMR (designated marksman rifle) employment.
