Accuracy International was started in 1978 by a group of national and international target shooters, one of which was a two time Olympic Gold Medalist. Designed by shooters, for shooters, the Accuracy International Chassis System (AICS) presents Remington 700 shooters with an advanced chassis system that is not only superbly functional but ergonomically inclined as well. The rugged platform of the AICS combines the leading characteristics of steel and polymer. Featuring a full-length, aluminum, self-aligning, self-bedding vee block this system more than supersedes traditional bedding practices. This replacement magazine for the AICS is manufactured from industry-leading corrosion resistant steel. The case overall length is 3.745".
