Not the greatest pic.. I only own a cheap digital cam. I'll sell the 37mm with the Hbar mounting kit and handguard for $125 + shipping and insurance. Payment through Paypal(NO 3%) and money orders. I have a spare mounting kit I believe for the CAR15 barrel I'll throw in for spare parts but I do not have the CAR handguard. note: few scratches on the barrel nothing major. Maybe interested in trades. I'm thinking of building a A2 config. 16" postban upper.
