All maple ridge barrels on TNA have those break in instructions at the bottom of the page. Of course you can rock any barrel without doing any break in steps and it will probably work fine. But it’s good practice to do something and those instructions seem like a good practice as it covers things like gas block being secure and checking for bolt wear. I’d say play it safe, do the step, if there’s something wrong you’ll catch it right away and hopefully get refunded or replacement.
