CTW 120rd high speed mag problem

They should be 12o rounders but can only load them with 40 bbs.
Have five of them and they are all the same.
Any tips?

Mine we're pretty hard to get the rounds in the first couple of times from the speed loader but that was it. It could just be the speed loader, but you could always take it apart and check it out. Just watch the springs and little pieces you don't want to loose any of them. Merry Christmas

Thanx. Little violenece did the trick.
Cant wait untill saturday to put my new baby on field.

Perhaps the inside of the magazine is dry because of winter. Try to spray a little Marui silicon oil. NEVER USE WD40!

hi
the follower gets jammed in the bends inside the mag i took them out of all my maggs and they work ine now . just replace the follower with two bbs .
