I took my csa vz 58 in 223 out to the range the other day, and I was interested to see how it would function with the ar15 magwell adaptor in it. I noticed that when I inserted my pmag into it, the lip of the mag would catch and activate the bolt hold open, making it unable to fire. I removed the bolt catch so I can at least use the gun now; but now i notice that when I insert the 5th round into the mag, aka the bullet is on the left side of the mag (facing forwards), and insert the mag on a closed bolt, the bolt still catches on the round and wont cycle, but if I hold the bolt open, insert the mag and then close the bolt akin to a garand, or if I remove a bullet so that the top bullet is on the right side facing forwards, it functions fine. anyone else notice/have this isue? On an empty mag the bolt still seems to catch on the mag follower. Is that just something I'll have to live with, or is there a way around it? I bought it with only the magwell adaptor, I dont have the original magwell and mags so cant testify to the "normal" function of the rifle. Otherwise i love this gun.

I believe CSA stated only usgi mags for the adapter. I think the Gen3 pmags are supposed to resolve these issues to work with more rifles that use AR mags, and I believe one of those issues was the bolt catch.
IIRC tv-presspass had a video about modding pmags to work properly in the Tavor, I believe it was for the same concern.

Gen 3 pmags are what a polymer mag should be. 
I also had issues with some 10 round lar mags that would do the same thing, when the adapter finally broke the feed tab on the one side I went back to using the factory mags and have had no feed issues since. The adapter is a nice concept but lacks the durability for anything more than cassual plinking at the range. I would source some factory mags , I belive Kelly's online sportingoods had some a while back. I chose to use the stock mags because if the gun don't feed then she is just a big cumbersome club , It needs to go bang . The 10 round thing is nice and CSA should make a VZ pistol with dedicated marked pistol mags for the Canadian market then we get our cake and eat it too LOL.
No it's the same issue that you had with the PMag's and your tavor.Gen 3 pmags are what a polymer mag should be.
Do the same mod to make it more like a USGI square cut out.
