Free: Contests & Raffles.
We put together a few from Bear Creek Arsenal recently..... and they are accurate by my standards.Had one problem, returned it, they made good.
I'm a fan of Ballistic Advantage.
I have a spare upper laying around that I'd like to make it into a varmint rifle. I'm thinking .223 Wylde but which one? There are dozens of options. Any suggestions on a reasonably priced, accurate barrel?
