Man, I can't find any discussion on the HK53 anywhere. The HK53 is one of my, if not favorite black guns. Why is it not as popular? And it's big brother the HK33. I know it is not current, but neither are a lot of other older rifles. Is it lack of availability? I have not seen any for sale other than out of US sites. If they are available, I would like to get one(semi only model) when I eventually get my RPAL. Also, with the HK33 is there a semi only model available that is NR.
