Which brand/caliber mags you using?
I bought a Magpul Pro stock for a future project. It is currently parked under a Rem 700 LTR .223 with MTD mags and no problems. I put it on this rifle to evaluate the stock and get used to the adjustments.
I just now stuck a Magpul 308 AC mag into the stock and no issues but that is on the 223 rifle/bolt.
Following. I bought the stock for a future Bighorn Origin project.
