A long time ago I put together a Defiance Tenacity (s/n 123) with a NSS Criterion 6XC barrel. Barrel is 26", 7T, with trued barrel nut. Has Area 419 (I think that is who made it) oversized bolt handle (original will come with it as well). Haven't put a single round through this but did bed into a stock, but as you can see from the pictures the action is very clean (minus the dust from sitting in the safe so long). Feel free to request additional pictures of anything. I have some additional pics uploaded to the google drive link below. Would like to get $1,200 shipped and insured for the barreled action. Reloading stuff you can see in the pics in the google drive link can be purchased as well, just not sure what I paid for it and the other 6XC stuff off the top of my head right now.
