i like the internal one the best with the stripper clips(aka. mag. loaders)for the sks. mine never had a problem with a five round mag., but also never got to try a 20rd. the catch on the duckbill never would seat right. cool thing though is it only takes a minute to change that out anyway.
just saw the tapco stock too.. i bet that is why..lol
i had thought about getting one but just got another weapon instead.. how is it?
