Let my dad borrow my Polytech AKS-223 and he fired a few rounds and finished. Thought he would clean it before bringing it back to me. Sounds nice bit what he did was accidently put a 9mm bore brush on a metal wire braided bore snake and try putting it through the chamber to pull upwards to clean the barrel. Obviously, the rifle is 223/5.56. Any thoughts on how I can get this out of the barrel without ****ing it up? Anyone experienced something similar? Can' be too mad at my dad because it was an honest mistake. Any advice is appreciated.
