Midway has a nice smooth DPMS stripped upper receiver for $79, and the normal design with the brass defelctor for $99... about $10 discount each. Depends on your preference.
I just ordered the smooth upper for a .22 caliber SBR upper I'm planning.. $79 was about as cheap as I was going to get a stripped upper without finding blems in stock somewhere.. Seems everyone is keeping the inventories low...
I have 2 stripped Lowers on the way engraved with my trust info for SBR'ing..... Both Marked "300 AAC Blackout" for the Caliber... guess what one of my NEXT upper builds will be......?
