Could be better! - Magpul Industries PRS GEN3 Precision-Adjustable Stock for AR15/M16 and AR10/SR25 platforms

I bought this mainly because I like precision shooting and wanted to build a AR10 .308 caliber rifle, I’ve always wanted an AR10 rifle I could say I built!
I think the Magpul Industries PRS Gen3 stock is exactly what this rifle needs, but there is only one thing I don’t like about it and that’s the comb height adjustment! I’m not sure why but it is very hard to adjust, I’m 55 and a mechanic and I know I have some arthritis in my hands but it’s darn near impossible for me to adjust. The length of pull is easy but the comb adjustment is terrible!
