EVERY new rifle needs to be cleaned and gone over for torque. All scope mounts and rings need a touch of locktite or nail polish. Even assuming they were torqued properly from the factory, it is normal to check for snugness after a few shots, the same reason you re torque lug nuts after 100 km. Not checking is a lesson that those new to firearms need learn only once. I am sure most of us have been there...
Very few rifles, and even those of the highest quality in the sub $3000 range, don't need a little attention when new. A burr here, factory crud here, a loose screw or bolt, its going to happen. Unfortunately this is the landscape of today's firearms. And the lower you go on the price grid, the more you should expect. Cleaning the burr off the extractor of a new CZ mauser copy that thought it was a push feed reminded me that even the best factory produced rifles, are just factory produced rifles. But I sure felt confident stepping afield with a rifle I knew functioned perfectly, and was sighted in as finely as could be. And this was tested on at least 3 trips to the range or out just to plink before I even considered firing at a live target. It took me 10 minutes to diagnose, and 5 minutes to remedy an otherwise flawless and very fine firearm. When pursuing a bargain, it is fine to expect the best. Just plan for the worst...
