I am looking to purchase a vz58 Sporter, with the folding stock and 7.5" barrel. I have seen it available in .223 as well as 7.62x39, and I am wondering what the pros/cons of each are. I already have guns in both calibers, and the cost of ammo is comparable. I like the idea of the 7.62 more because I think it would be more fun as the thing is basically just a big pistol, however the mags are sort of limiting and the idea of shooting corrosive ammo through a $900 gun doesn't sit well with me. I have heard of magwell adapters that allow the use of AR mags with the .223 vz58, including the LAR-15 mags which I already have several of. Has anybody used one and if so are they any good? That might be the deciding factor for me. Any other advice or recommendations would be greatly appreciated. Thanks.
