S&W MP-15 Owners....quick question.

[bang_bang]

I have had my MP-15 for about a year and a half now. My friend just purchased his a few weeks ago...the exact model as mine.

We went out shooting, and we were both looking at the rifles when he pointed out that there was a small difference between the two. Where the serial number is, mine was marked "SM XXXXXXX" while his read "SN XXXXXX"

I'm curious as to how many rifles are marked SM. I never noticed it before, but I would think SN would be the more correct marking to denote "Serial Number."

Then again, SM could stand for "Serial Marking" or something to that nature?

What's your rifle say? SN or SM?

Some manufactors use letters to indicate the month the item was made. That is probably the case here.

Call S&W and ask them.

I picked mine up a couple of years ago and it's SW XXXXX. I always assumed the SW stood for Smith and Wesson, but I guess I was wrong.

Sierra Mike 39xxx for mine. Purchased May 2009 (no idea how long it was in system).

I purchased mine in May of 2009 as well.

Guess it does have something to do with manufacture coding. Thanks!
