These are a nice alternative to the all steel AICS type box magazines. These Magpul 5 round mags are very light and work well with our BA Rifles and Chassis.
These mags have an internal capacity of 2.850 for your COL. Works with 308, 6.5 Creed, 6mm Creed, 6.5×47, 243 and other short action 308 Type Cartridges that has an COL of less than 2.850.
The feed lips may need a very slight modification to open up the clearance for bolt head travel, but this can be accomplished very easily with either a polishing wheel, dremel or file.
DO NOT ORDER THESE FOR TIKKA T3 CHASSIS
