They are very, very good. I talked to both Paul and John when I was deciding what I wanted to order. I wanted a lightweight gun very similar to a RRA predator pursuit, with a 20" barrel. Paul recommended a varmint contoured barrel, fluted under the handguard and in front, turned out to be exactly the gun I wanted. Nice weight savings and a 1/2" gun with factory HSM ammo. I think it will do better as I play with handloads. My brother took one look and ordered the exact same setup. I absolutely would recommend them.
