M40 A3 Bolt-Action Sniper Rifle Magazine

THE M40 A3 SNIPER MAGAZINE ONLY FIT IN THE M40 A3 SNIPER REPLICA.

NOTE THAT WITH EVERY MAGAZINE IT CAN HAPPEN THAT THE BB'S DO NOT FEED PROPERLY ON A CERTAIN BRAND OF REPLICA.
THE ADVICE IS TO TRY A DIFFERENT BRAND OF MAGAZINE, IN ORDER TO SOLVE THE PROBLEM.
