Purposefully designed for use with cylindrical actions such as the Mausingfield and the Remington 700 type short actions, the ARC mag offers a compact 10-round alternative to the Accuracy International CS type magazines.
10-round ARC Mag is only 3/8” (10mm) longer the 10-round mag AI AW.
Does NOT require an “AW cut” receiver.
Constructed from corrosion resistant and high strength stainless steel.
Cross section is identical to that of the AI CS and the AI AW mags designed for use in short actions.
Internal length is nominally 2.97 inches (75.4mm.)
An easy to remove floor plate makes disassembly and cleaning easy.
For reliability, it is very important to keep the magazine clean and to ensure that only clean cartridges are inserted into it. Cleanliness will reduce the friction associated with the relative motion between cartridges and between the cartridges and the inner walls of the magazine resulting from the cartridges transitioning from the double-stack to center.
