HK Clones and Conversions

This page is intended to provide information on third-party copies and variants of HK products. Very very incomplete at this point. If you have anything useful to add, please post a message in the boards or send me some mail. If you have any information on Fleming or Vollmer's products, write me!

Note that firearms such as G3 clones that are described as having been converted to full-auto are built using federally registered pre-1986 parts. Don't try this yourself unless you are very familiar with the legal issues involved. NFA stands for National Firearms Act, and designates firearms very difficult and expensive to acquire legally. LEO stands for Law Enforcement Only and indicates firearms impossible to legally acquire outside of police and military use. So much for Constitutional rights...

Sorry there are no pictures of the guns on this page. Wanted to keep the page where it would load quickly. Follow the links to see what the guns look like.
