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 Long Action BA Rifles and Chassis.
These mags have an internal capacity of 3.5″.
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.
If this will be used in an MPA BA or BA Lite Rifle, we can, by request, make this modification for you. On the notes section at checkout, please make this request.
