Michael,
Your question about hunting with a suppressed rifle was referred to me for an answer whether hunting with a suppressed rifle was legal in Colorado, specifically small game). I am under the assumption that when talking about a “suppressed rifle” that we are talking about a firearm with some type of “silencer” on that firearm. For the purpose of hunting in Colorado a rifle is defined as a firearm fired from the shoulder, with a rifled bore, having a barrel length of sixteen (16) inches or more and a minimum overall length of twenty-six (26) inches and is defined in Wildlife Commission regulation. Depending on the small game species that one is hunting, there may be further restrictions on bullet weight or foot-pounds of energy produced. There are also further restrictions on what a legal rifle is to hunt big game. Therefore, the answer to your question is a “qualified yes”. There may be other state statutes or federal laws and regulations that prohibit it and there are certainly some conditions that have to be met to hunt with a “suppressed rifle” that I am aware of.
Any “suppressed rifle” must be registered in the National Firearms and Transfer Record as defined in the National Firearms Act and in federal law (27 CFR Part 479) and a permit issued to that person. A photocopy of approved permit should be carried by the owner when the weapon is being transported. Colorado statute defines a “suppressed rifle” as a dangerous weapon and it illegal to possess with a couple of exceptions such as having a permit (Title 18, Article 12, C.R.S.).
I would encourage you to contact the Bureau of Alcohol, Tobacco, Firearms and Explosives with the federal government and the Colorado Bureau of Investigation with the State of Colorado to see what permits, licenses and restriction there are for possessing and using a “suppressed rifle”.
Thanks!
