Was going to buy the PRS, but no one has them. So I thought I'd give the Luth a try. It's lighter than the PRS, which is good. Better than the PRS if you want a shorter LOP. It's adaptable every way. Should've come with a QD swivel cup. The softer butt pad is pricey. Should be OK. Just got it, so we'll see.
This is a an excellent piece , it is well molded, all edges are nicely finished so you have no sharp spots to deal with. The adjustable length and height allows it to fit almost any shooters fitment needs quick and repeatably, just use and ink pen to make tick marks for each shooter. The addition of a screw to take up slack between it and the buffer tube is a great feature, it allows a firm solid fit with hampering adjustment. The one little nuance that you should be aware of is with the locking pin, it has a small cut out that allows it to ride down over a protruding stop on the front portion of the stock to allow for mounting and dismounting. If the pin is not rotated after assembly to prevent that, you will pull the stock off the tube every time you try to extend it.
