Absolute waste for ars! - Hoppe's 9 Viper Cleaning System

Let me start off by saying that I have 9mm, 45 cal, and 12 gauge bore snakes and they all work great. I use them all the time and would recommend them highly. I recently purchased one to clean my BCM AR-15 due to the ease of use and efficiency with other calibers...huge mistake to say the least. I started off by dropping the weighted end through the barrel and attempted to pull it through like I normally do. Much to my dismay it wasn't going to be easy. I pulled it partially through the barrel but it became so tight I had to literally brace the stock between my feet and pull very hard with both hands to get the bore snake through entirely. Hopefully it didn't cause any damage to my very new barrel. Great job Hoppes
