I like getting low as I can to the ground when i shoot or when I'm bench shooting I do not like to have to stretch my neck all out of wack jest to shoot. how low can you go with a 30 round mag , it's not about the money it jest saves my neck , I already have the pmags and Thay stand to tall , it's jest a better position when you do not have to struggle all over the place jest to shoot ,I see so many guys struggling at the range trying to line up there rifles on the bench with the pmags and always complaining I need to get a 20 rounder mag because it's shorter and I wouldn't have to try and adj every thing, besides this is a 50 round mag I do not have to reload as many times , that way I can focus more on my target and enjoying what I went to the range in the first place for ,
