From Blackfork:

The government is destroying M14 rifles that could be sold by the CMP.  Here’s a petition to reverse that process.

The CMP sells surplus military surplus arms to support its purpose of promoting civilian marksmanship.  I think, and hope they have made millions in the past decade selling carbines, M1s, 1903s, P17s and Krags.  So far they can’t touch M14s because there is a full-auto capability.  It’s easy to permanently disable.
