Where can I buy 5.45 just the upper?

[Nathan Forrest]

I didn't find them for sale on the S&W site. Thanks for help.

They are available at Discount Ammo & Hunting Gear, Camping & Outdoor Equipment, Military Surplus & Clothing | Sportsman S Guide at Sportsman's Guide, item WX2-142208. Don't know if it is at the best price though.

He is looking for the russian 5.45X39 not the 5.56X45.
A good choice with the current ammo prices!
The round itself is interesting too.
