2 problems with mp7a1 (any help would be great)

[bailey5671]

i was cleaning my gun to day and found one of my cylinder return springs was busted, im hoping to get it replaced at gearbox and i was wondering if i should get it replaced? it shoots fine and all but i just wanna know for sure.

next is that my magazine no longer engages the bolt catch when empty and becomes very difficult to remove the magazine, but when the follower is locked in position the mag removes quite easily, so i believe the problem is the follower. has anyone else had this problem and im wondering how they may have fixed this because the kwa pro shop doesnt sell followers.

any help greatly appreciated, thanks guys

CLEAN YOUR GUN!!!

The sticky mag is probably from dirt and dust up in the magwell, so clean every inch of it.

thanks terreus, but that didnt solve anything. after cleaning the mag and the magwell twice it still is not working properly, but i now pinpointed the problem, the follower isnt able to go all the way up into the mag which would explain why the bolt catch isnt engaging and explain why its difficult to put the mag in and pull it out because of the follower possibly being deformed. ill take it to gearbox and see what they can do.

I'm guessing you dropped the mag at some point. Replace the magazine lip.
