Note that the strap on the AR-15 is not correctly installed. The center gun is my new SOCOM 16, an M-14 (or M1A) derivative with a 16.25 inch barrel. I bought the wood stock for it about a week after I got the gun. It looks very nice in wood.
The Garand on the right was used in Korea. My friends and I all bought one when they were incredibly cheap (like under $300 if I recall correctly, long time ago). Mine's been re-barreled, glass-bedded, I finished a new stock, it has match sights and a match trigger. It's very accurate.
The AR on the left is a Clinton-era Bushmaster AR with match trigger and the chrome-lined bull barrel. It's very accurate, especially if the sling is installed properly and used! :-)
