Do not know about product prices or salesmanship here, as I went here for gunsmithing services. Simple gunsmith task requested - change out a muzzle brake. I provided the brake and the shims and an offer to provide lock-tite. What resulted was amateurish at best. Muzzle brake was slightly off center, with a re-used crush-washer resulting in a non-trued muzzle brake. $5 was what it cost, and I got what I paid for (had it redone properly elsewhere). My view- Do NOT go here for gunsmithing. If they can screw up a simple muzzle brake install, no telling what you will end up with if you want something more complex/sophisticated.
