In 1997, after the ban, I purchased a Polytech Legend National Match (Pre-Ban) from Gulf State Firearms (at one time, a very reputable dealer). This firearm is marked National Match on the milled receiver. However, it has a short barrel, similar to an AKM/AKS. I have heard that some people have seen short barrel variants of the national match. I am trying to find out how this rifle came to be....1) it was intentional from the factory, that is, a rare variant, 2) it was a mistake at the factory, that is, they built a Legend using a National Match receiver, or 3) someone bought a national match legend and hated the barrel length and paid a very skilled gunsmith A LOT OF MONEY to do a conversion. If you know anything about this rifle, let me know as I have been trying to solve this mystery for years. Thanks.
