you'd be correct. Unfortunately, there is another side to it.
The International Action Network on Small Arms has a great deal of influence with the conference, and they have been trying very hard to piggyback some restrictions on legal firearms trade on top of the conference's main focus.

To maintain public safety, civilian gun possession must be
recognised as a privilege with associated responsibilities for
maintaining public safety. In most countries, in order to drive a car,
applicants must pass a test proving their fitness to drive before a
licence is issued. If a car crashes killing a pedestrian, the owner of
the car can be identified by checking the registration plate which
will be linked to the owner’s name. Guns are specifically designed
to kill. Yet the majority of countries do not have effective licensing or
registration systems for guns.
Regulation of guns in civilian hands was omitted from the
agreement in 2001 and thus did not form part of states’
obligations in the Programme of Action. Despite this, 70 per cent
of governments have included information on controlling civilian
possession in their reports to the UN since 2001. Governments
clearly understand the importance of regulating civilian possession
in order to prevent diversion; it is time for the UN small arms
process to recognise it too.
Governments should agree to:
• Promote gun owner responsibility by requiring all firearms to be
registered. Individuals permitted to own guns and ammunition
must be held to account for their security, use and misuse.
• Define minimum criteria for private ownership of guns with
a national system of licensing. These should include proven
capacity to handle a gun safely; knowledge of the relevant law;
age limit; proof of valid reason; and a security screening based on
criminal record or history of violence, including intimate partner
violence. Licences should also be required for ammunition.
• Prohibit civilian possession of military-style rifles, including semiautomatic
rifles that can be converted to fully automatic fire and
semi-automatic variants of military weapons.
• Block access to guns for people with a history of violence,
particularly against intimate partners or family members.
• Introduce safe storage requirements to prevent gun accidents,
suicide, misuse and theft.
• Regulate manufacturers and dealers. A national register of all
manufacturers and their distribution network, including firearm
dealers, would help prevent diversion to illicit use.
I'm all for controlling illegal arms trafficking, as long as it doesn't include making trade in military surplus collectibles, handguns, and nonhunting-style long guns illegal. However, that is precisely what IANSA is aiming at--and, perhaps, why U.S. domestic gun-ban groups are making such a big deal about a UN convention on small arms.
Is the NRA's rhetoric exaggerated? Almost certainly (and FWIW, I am not currently an NRA member, though I used to be one). But IANSA has made no secret of its desire to use UN action on small arms to pressure the US into adopting Australia-style gun restrictions, and I think that is a legitimate concern.
