View Full Version : AR-15 Platform Question.

April 25, 2010, 07:26 PM
I have seen yes and no on this. I have a S&W M&P-15 chambered for the 5.56mm round. Can I get an upper for this platform chambered in the .308 that will just replace the .223/5.56 upper, and be ready to shoot?

My Google foo is weak on this for some reason. Thanks for your time.

No the lower is totally different.
