For $350 per rifle, most LE agencies are able to take possession of some older M16A1 (FA, pencil barrel, tri-angle forearms, etc) from the Feds via some buy-out programs. It is a win-win situation for both levels of govt. The Feds get rid of some weapons they dont need and are just collecting dust, and the local-yocal LE agencies get some very cost effective patrol rifles they never had.
I dont know 'bout any of you guys... but I'd MUCH rather have an M16A1 than a Mini-14.
There is a local PD that just took possession of four 1983-ish "vintage" Ford Broncos from a local National Guard unit. The exteriors have all been painted white and have had the proper decals applied (lights, too), but the interiors have all been left that UGLY olive green. Word is, they'll be used during snow storms, high water situations, and any other off-road situation that might arise.
