Can I carry my AR/AK pistol concealed in Nevada?

​It is legal to carry a concealed large unconventional pistols, like AR/AK pistols, if you have a concealed firearms permit. Technically, this includes carrying them in a firearm case vs. under clothing large enough to conceal them. Nevada is an “on the person state,” meaning any bag or container carried where the firearm is not “discernible by ordinary observation” makes the gun concealed, and thus handguns require a permit.
 
NRS 202.3653 defines “Concealed firearm” as "a loaded or unloaded handgun which is carried upon a person in such a manner as not to be discernible by ordinary observation." The definition of a “Handgun” is referred to 18 U.S.C. § 921(a)(29), which states: “The term ‘handgun’ means — (A) a firearm which has a short stock and is designed to be held and fired by the use of a single hand; and (B) any combination of parts from which a firearm described in subparagraph (A) can be assembled.”
 
By black-letter law, it is technically illegal to carry anything that isn’t a handgun concealed, including a rifle or shotgun in a long-gun case, even if the case is obviously a gun case. NRS 202.350 (d)(3) prohibits carrying concealed upon the person a "pistol, revolver or other firearm, other dangerous or deadly weapon or pneumatic gun." 8.(a) defines "concealed weapon" as "a weapon described in this section that is carried upon a person in such a manner as not to be discernible by ordinary observation." NRS 202.3653 to 202.369, the concealed firearm permit sections, provide an exemption for handguns only.
 
This is legislative oversight and we have no information anyone has ever been charged with a crime for this, especially anyone innocently carrying a gun to a range, etc. (including cased handguns). Officers tend to use their discretion here and any such arrest would likely not be charged by the DA or withstand a trial or legal challenges. In other words, don't worry about it. If the government ever presses the issue, they'll have to make legion of exemptions as California does or basically forcibly encourage anyone going to the range with a long-gun openly carry it (which the politicians and cops won't want people to do).
 
So long story short, if you have a CCW, yes, you can carry your AR/AK or whatever pistol concealed. The erroneous belief likely stems from the days of “blue cards” when police would refuse to register such weapons or when revolver/semi-auto qualifications were required for a CCW.
