There is no question that pro-gun people on a pro-gun website will push for a pro-gun assessment.
The reality of the situation is that the law was written by and will be read, interpreted and applied by anti-gun police, prosecutors, judges and even juries.
If GSG calls it an AK-47, you'd better believe their catalog will be the first exhibit at your trial. Your defense is then "it's rimfire, not centerfire." DO YOU THINK ANYONE CARES ABOUT THAT DISTINCTION????
You're better off declaring the item then fighting them about the letter of the statute when they attempt to confiscate it...that way you maintain your credibility and the legal high ground throughout the process.
The fact of the matter is that only centerfire AK47s are banned, but without a declaratory ruling from the state police, or the board of firearms permit examiners, one can expect a police officer to arrest and "let the courts sort it out" at the mere mention of an undeclared AK47.
The statute bans:
"Any of the following specified semiautomatic centerfire rifles, or copies or duplicates thereof with the capability of any such rifles, that were in production prior to or on the effective date of this section: (i) AK-47...
Would you rather risk having ONLY this plinker confiscated later, or lose your RKBA altogether when you end up with a felony charge/conviction for failing to declare an "AK47"? Seems like a pretty clear choice.
There is no gov't agency in CT that is concerned with getting things right...they are merely concerned with "making an example" of anyone who chooses to exercise their rights (which they only grudgingly allow) and happens to slip up. Look at this year's gun-related arrests in the news. They're even OK with arresting law abiding citizens and "letting the courts decide."
Don't give them an easy way to nail you.
