M.E.U. GBB Magazine 28rds

MAKE SURE THAT YOU LEAVE GAS IN GBB MAGAZINES AT ALL TIMES.
THIS ENSURES THAT THE RUBBERS OF THE MAGAZINE DO NOT DRY OUT AND CAUSE LEAKS.

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.
