Here is the picture of the barrel.
I pulled this barrel from a brand new LM8 MRP rifle. The reason it has an AAC blackout is because I change the A2 muzzle device as soon as I get a new rifle. This has never been shot other than by LMT for testing (They do that to all the stuff they manufacture which is great in my book). Below is the link for the barrel on sale. MRP barrel assembly link.
Asking 350 shipped from IL.
