|These mags are perfect. I've fired a few hundred rounds through 4 different specimens without a single malfunction. The plastic is thick and they do not feel flimsy at all.
In my experience, these may be difficult to seat properly with 20 rounds in the mag and the bolt closed. Therefore, I cannot "top-off" the mag after chambering a round. Not a big deal in my book, though. Just makes the SKS a 19+1 weapon instead of a 20+1.|
