They come with very useable mounts. Not the best looking, but they function. The T-3 s a workhorse rifle, not a showhorse anyway. I'd use them, but would recommend changing the screws. The ones I've owned quickly had the soft metal factory screws let the hex screws slip and round out the screw head. It cost me $3 at Home Depot to replace 6 screws. Better than spending $50 for new mounts. After that 1 modification I found them to be as good as anything.
