So I've got a rifle that has these Weaver style aluminum scope bases on it. The problem is while the previous owner had it, one of the rings was missing the nut to screw it tight and the screw wore into the base fairly deep. Now I've got a set of Burris rings I want to use, and wanted to use these bases temporarily. I've used them before in good shape and had decent luck with them so was going to try to again. If my plans work out with this rifle I will need to change to a canted base later on, but right now I need a regular base. I hate to spend $80-100 on a good base right now, only to toss it and have to buy another one in 3 months. So I'd like something to use in the meantime. I'm debating if I should just use these or if I should buy a $15 Weaver base that will be identical without these marks.
Now, when I put the rings on there, they seem to clamp down tight, but it's obviously hard to tell how they will do under recoil. The chewed up part only seems to affect the channel the cross bolt sits in at the very end. The ring also goes slightly past the chewed up part.
Here are a few pictures of what the base looks like.

Do you all think these will be fine to run, or should I shell out $15 for a new set that will be nearly identical? I just wanted to get a general opinion on this. The cut does go fairly deep, but the ring still seems to clamp around it.
