Had a 277 WLV barrel for a AR on order and had it sent to the house via USPS. after I got the notification and by the time I got home some turd stole the box that contained the barrel. It's a 18 inch stainless, mid gas with threads. The WLV is a 556 case necked up to a 270 bullet. It's a cat and there is no ammo available at the store for this round. Not to many of these barrels around. If anyone comes across a barrel marked 277WLV or 277 Wolverine it is probably the one some turd stole from me.
