If you are good at keeping your firearms cleaned and checked, should have no problem. I saw what they had on their site and the synth. stocks were priced well. I know three game wardens who carry their mini-thirty. Wood stock. Not very different from the ranch rifle, really. But it prices out more. I've shot the ranch rifle (wood stock) in 5.56 and the mini-thirty 7.62 before. Very adequate for a ranch rifle. The 7.62 I shot had capacity of 5 rounds. I liked them both. 7.62 was accurate enough for my view. I have not, however, shot either in the synth stock.
There are some who prefer looking at the Springfield Arm. 30. But that won't handle with the ease of the ruger mini, due to size and (I think) 3 more pounds in weight.
Still partial to my lever action when we are out doing work.
I doubt any of this helped, but it got me away from working on a spreadsheet.
