M4 Hicap Magazine 300rds

A METAL MADE MAGAZINE WITH A CAPACITY OF 300 BB'S.
THIS IS SUITABLE FOR MOST M4 MODELS.

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.
