Summer firearms 14 1/4" LOP vs, Winter firearms 12 7/8" LOP. I try to hike 5 miles per day summer or winter and in summer I wear shirt and survival vest. I the winter I wear two sets of long-johns, two hooded sweatshirts, and arctic outerwear coveralls. Do you have summer and winter arms.......? Yes I have gravitated too the 6-position telescoping stocks.
