I live in NH and we are one of the very fortunate "gun friendly" states . With proof of NH residency (valid I.D.) and being able to pass the mandatory NCIS background check, I can basically cash and carry out the door most all types of firearms. I also lawfully own multiple "NFA" type items that are in many states illegal (silencers and rifles with barrels <16" which are categorized as "SBR" or Short Barrel Rifle" ) . I have to pay an additional $200 per NFA item, fill out a lot of paperwork, be fingerprinted and wait up to a year for approval. I also have a concealed carry handgun permit.
Here's a great gun talk thread I started a while back :
