I have a barrel for a Ruger 10/22 or charger platform in 22 long rifle. Its a steel blued bull barrel. Length is ten inches and its threaded 1/2 -28 with a thread protector. The maker is HI-desert Dog. I installed it on a pistol platform and shot maybe 100 rds through it. I'm looking to sell it. I believe I bought it back in or around 2008. Asking $75. Thanks all for looking hit me up if you have any questions.
