I took a $7.49 flyer on an 10/22 buttstock pouch from Amazon hoping it would work on my PC Carbine. I was more than pleased. The pouch fits tightly on the stock and is held in place by the sling swivel stud. The pouch has an outer flap with a loop closure and an inner zipper. The best aspect of the pouch is that it holds three 17-round Glock magazines.
