Mag extension on pre b mags

[Crazy8]

Does anyone know if mag extensions will work on the pre b magazines, which are a little thinner?

Not 100% but, you might try Armanov +1 extensions. I purchased a couple for my Arsenal Strike One a while back. I’ve put them on every CZ/Clone mag I’ve had and they’ve worked without changing the mag spring since they’re only a +1 extension. They’re made of aluminum and, if needed, can be thinned out very slightly to make the mag lock in properly. That’s been my experience so do with that what you will. Also MecGar used to make an aluminum +2 extension, and they can still be found occasionally, but that may cause you to search for a replacement mag spring to make the slide lock open on last round. Hope this helps.

I have the ones that are for “polymer floorplate”. You would of course want the one for “metal floorplate”, which are harder to come in my experience. Again, just a suggestion.

Thanks! I managed to find 2 of the mecgar extensions in red, which matches my red lok grips.
