M4 Midcap Magazine 140rds

A QUALITATIVE PLASTIC MADE MAGAZINES WITH A CAPACITY OF 140 BB'S.
THIS IS SUITABLE FOR ANY M4 / M16 REPLICA. Because the magazine is transparent, it is easy to keep track of how many BBs are still in it.

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.
