Is there anybody anywhere who makes good working magazines for a guy who wants to shoot 7.62 X 39 ammo out of his carbine? I am thinking about getting an M-4 variant that shoots 7.62 X 39 ammo but if I can’t get decent magazines for it, why bother? I already have 4 variants in .223/5.56 and want to play with or test a slightly larger cartridge.
I agree, try the C Products mag, they have done very extensive work to build a good mag. I cannot, however speak from personal experience, but I have a friend that assisted C Products with working kinks out of the design and the last I heard things were looking very good for a good quality product and I noticed that C Products is selling one now so I am guessing that it works.
It can be curved below the magwell but must be straight in the mag well. No way around this in a standard lower. The follower and spring are critical. Everything has to be just right. Hence the feeding issues with the x39 round.
