Seems like the Luth-ar only has two settings for cheek weld. Normal placement and high. This could very well be me not knowing how to adjust it. Mostly likely the case.PRS is much heavier and more solid. Luth AR is lighter and has more adjustability. I have the Luth AR on my 308 AR and like the way it sets up.
My rifle needs a longer drag bag now, I’m 6’ so its a perfect fit for me. Only have the length extended about 1/2” and the comb up about 3/8” but it made a huge difference over the carbine type stock that was on it before.The only issue is the Gen 3 has a much longer LOP so it's a touch too long for some folks.
