If we are defining "military weapons" as "crew-served and/or fully-automatic weapons", then this is not true. An example: an automatic (burst- or full-auto-firing) rifle is a Class III weapon regulated by BATFE. It is not legal (and hasn't been since registration was closed in 1986) for newly-manufactured ones to be sold or transferred to, manufactured or imported by, or otherwise put in the hands of non-law enforcement, non-military people who aren't federally-regulated firearms dealers. Key parts (e.g. lower receivers, sears) are regulated as Class III weapons in their own right and may not be used to make new Class III weapons except by a licensed manufacturer making them for LE/military customers. Transfers require prior approval (can take up to a year if there are no issues) by ATF including a background check and signoff by local law enforcement, and the recipient must pay a tax and keep the resulting paperwork available along with the weapon for inspection upon request.
The net effect is the supply of truly military weapons legally available to civilians is small and monotonically decreasing, and the ones in the pool (including those key parts) are quite expensive and potentially rather aggravating to buy and keep.
