Brownell's 6.5 grendel barrel by Satern and Maxim bolt. 18 inch, midlength gas, 5/8-24 threads, and bead blasted. I bought this directly from Satern to convert an ar15 for my boys to hunt with. Ended up buying them both bolt actions. Less than 100 rounds on both. 250.00 shipped. Paypal friends and family or postal money order.
