Hi people, new to this forum. I just got myself an Saiga 7.62x39 sporting rifle. I saw an AR magazine conversion kit. I know it only works with 223, but shouldn't it work also with the 7.62x39 AR magazine? Because AR15 7.62x39 magazine a lot similar to the 223/5.56 AR magaizne, but just in 7.62x39 caliber. Shouldn't the adapter conversion work with the AR 7.62x39 magazine also? Any input?
