Classic Army MP5s and their lowers

[tomson2912882]

Hi guys,

I have the A5 model of the BT-MP5 by CA but the selector switch broke by shattering in the middle of the rod that connects the two together.

Its a naff design and extremely flimzy meaning im having to constantly see to the grub screw to keep it locked and tight.

I would like to change to the A2 lower as im told its a much better design and far more sturdy.


Is it a straight forward swap or are they designed differently?


Thanks guys.

Re: Classic Army MP5s and their lowers

have you tried threadlock on your grub screw?
If you use blue thread lock (middle strength I believe) that should hold the grub screw.

can't help on the other thing sorry I'm an ICS mp5 user.
