AM-TAC Precision has a great unpublicized special going on right now for their Stainless Steel Match Grade barrels. The barrels are 5.56 NATO, 1:8 twist, Mid Length and Isonite QPQ coated. Available in both 14.5″ and 16″ lengths. When you order this deal your barrel will also come with a Low Profile Gas Block and Mid Length Gas Tube.
I used one of the 16″ barrels in an upper I built and they are seriously nice. Normally this combo would run $346 but special puts them on sale for just $285. As I mentioned this is not a publicized deal so you have to either call or email them for this deal. Phone orderers can call 208-906-0585 or you can email email@example.com.
For more detailed information on this barrel, head on over to shop.am-tac.com but remember you can not order this deal online.
