Its only about PR, nothing else.
If a gun owner is bragging around with his AR, like "it is tactical", it has "CQB sighting system", it has "High capacity mags", "and look at me how cool I look on you tube, in military tactical gear, blasting cans... "
The good percentage of public (who are not gun owners) will not see any need for such charackters and activity in local communitiy. Especially in urban and city areas.
The point is, majority of non-gun owners will see the need for such gear only in hands of police and military, not in hands of their neighbour, and this will be most in urban areas and cities
So this gives a bad PR and bad press
On the other hand:
If you show the same gear in another light: sporting competitions, respectable club membership (with code of ethics, ans match rules), proper language, avoiding military terms, various level of competition, follow sport and civilian dress code. The public will not mind (in most of cases).
The way how I see:
What is the biggest thing that helped gun owners being a gun owner in civil communities - world wide?
It is not 2/a - as in case of US, because other countries do not have 2/a.
It is not self defence - many countries do not have option for self defence gun ownership.
It is not hunting - as many countries have ban on hunt.
It is not historical gun collecting, as in most of countries are museums for that, civilians rarely or much less.
It is the sport!
95% of countries are members of some shooting associations, in most of cases it is ISSF, representing modern olympic disciplines.
And IPSC is catching really fast, as more and more countries are getting their national IPSC organisations. (Since recentely, IPSC is member of GAISF - Global Association of International Sport federations, which is extremely important as recogntion of international sport discipline).
In ISSF the largest shooting organisation of the world, presently there are 162 member states (out of 195 countries in the world), so there is 162 world countries that ultimately (can) compete on modern olympics games.
An no one - gun owner - or not- is disputing any firearm international sporting event, or the gun type use for that.
Nobody is talking about ban on guns used for ISSF sports.
Becasue, sport is generally accepted and recognised civilian activity.
That is real world, and how PR works
Bottom line is this.
Present your AR15, as sport discipline, even better international competition sport, and you will kill all bad press, and bad PR, and you kill public debate. You win political battle.
Present your Ar15, as something to shoot hogs from chopper for fun, and weekend plinking activities in backyard on you tube, in tactical or para military gear - Not all local public, and local (non gun owning community) will accept it or support it. This will create a dispute. Thats fact, becasue we are discussing it now.
And debate will continue for ever, or till eventual ban.
Any gun, in any country can get banned. Thats also fact. But the gun used for international sport shooting event, will very hardly get banned, beacuse each country wants to send their team to international competition.
