If the juvenile conviction is still on the record - and depending upon the nature of the offense, and whether or not steps have been taken to have the record of conviction expunged - C.B.I. will report that you are a person prohibited from firearm possession thus blocking any purchase from a dealer, or eligibility for a CO CHP.
Since it's only been 5 YEARS the juvenile conviction is still well within the TEN YEAR penalty prescription of CRS 18-12-108.
The Colorado Constitution, Article VII, Section 10, actually provides for the automatic FULL restoration of ALL of your rights of citizenship upon completion of your sentence, BUT the General Assembly, with a "wink" from State courts has managed to "amend" the Constitution of the people of Colorado through the statutory provisions of CRS 18-12-108. HHMMMM - weren't we all taught (in the public schools even) that a constitution can only be changed BY A CONSTITUTIONAL AMENDMENT ???
The grammatical construction of CRS 18-12-108 is such that the General Assembly would merit an "F" grade from any competent 4th Grade English teacher - even in the public schools. This bungling of the construction lends itself (conveniently) to gross misrepresentation of the time computation. Such misrepresentations focus on "prohibited for life" with some "penalty enhancement" (unstated in the text) concept during the prescribed ten year period in spite of the statute's presumed compatibility with the Colorado Constitution. CRS 18-12-108 language construction does clearly delineate the TEN YEAR penalty prescription - only to have it blurred by strained pretensions of wishful thinking on the part of certain vested interests.
The penalty prescription applies from date of conviction to TEN YEARS FOLLOWING RELEASE FROM incarceration, probation, parole, or other court ordered supervision (drug rehab/mental health, etc). The Tenth Circuit (U.S. Court of Appeals for the Tenth Circuit) has consistenly held to the TEN YEAR interpretation since 1994 when the statute was amended to extend its reach to any felony conviction - not just possession of dangerous weapons, burglary, arson, and use of force or threat of use of force. This holding derives from several decisions commencing with U.S. V HALL .
There exist a persistence within the Colorado criminal justice community, and anti-Second Amendment booster clubs (Brady Bunch) that Article VII, Section 10 of the CO Constitution only restores the RIGHT TO VOTE upon completion of sentence. This "consensus" strangely recognizes restoration of the right to hold public office, and serve on juries as well - but OH , NO - not the right to keep and bear arms ! Those folks would merit an "F" grade from their 2nd Grade reading teacher- even in the public schools. Article VII, Section 10 means exactly what it says - that ALL rights are restored upon completion of sentence under a COLORADO conviction , unless an exception is provided IN THAT CONSTITUTION - and there is no exception provided.
In regards to federal law 18 USC Chapter 44 - 921 (g)(1)/ 922 (a)(20) if that juvenile conviction has not been expunged , and your firearm right will not presumably be restored under Colorado law for 5 more years, then you are currently prohibited from firearm possession under both State and federal law at this time. Your status within another State's jurisdiction will depend upon that State's law, and its conjunction with federal law.
Unless the Colorado Constitution is amended to provide for an exception specifically restricting the right to keep and bear arms - and that will take so doing - Colorado officials are in a tight spot.
Keep in mind that THIS RIGHT is now extended protection under the Second Amendment to the U.S. Constitution through the Fourteenth Amendment. (McDonald)
Althought the SCOTUS made allowance for restricting the rights of felons, Colorado's provision for restoration of all rights provides no exception excluding persons previously convicted ("felons") UNDER COLORADO LAW from the rights restoration.
