I once tried a PFS stock, but sold it because it tended to lose its adjustments due to looseness...I imagine there is a "secret"/experience factor re. the best practice of keeping these things tight, particularly the cheek piece setting. I'm asking this question because I fear complications re. equipment, but the stock on my (very much liked gun) is too low. I hope to shoot again after a long hiatus due to "life" issues and so wish to have correct stock fit. Thanks in advance to PFS experts who may weigh in on this.
