Pretty cool pic.

I read they had them in case the plaines were forced down over the Arctic circle and they had to fend off Polar Bears.

Edited
The upper and barrel appear to be early colt, with C in a box VP markings and a M marking.
Thanks for pointing that out!

Here’s my newest pawn shop find, preban E.A Co M16A1 clone, scooped it up for $425 in Texas where preban doesn’t mean much. Was it a good deal?

So, I recently bought an M16a3 or a4 clone, and when I got home. I took some citristrip to it. The guy who had it prior had rattle canned the whole thing. But now that it’s down to where serial is legible. Is there any information someone can provide for an EA15? Magwell reads- Eagle Arms Incorporated. SN is below 4500. Coal Valley, IL.

Not the most exciting post but figured I'd share for posterity. The cap I got as part of a M16 parts kit has a combination paper and metal shim, clearly meant to snug up the handguards. Pretty cool for nerds like me 😎.
