This weekend the Alaska Gun Collectors Association is hosting its annual gun show in Anchorage, where bump stocks remained a touchy subject in the wake of this month's mass shooting in Las Vegas.

The National Rifle Association is standing firm opposing any legislation banning the use of bump stocks. The firearm accessories, which can be used to increase a semi-automatic rifle's rate of fire, have been under scrutiny since Oct. 1. That's when authorities say a gunman at the Mandalay Bay hotel in Las Vegas used them to modify his weapons before killing 58 people at a nearby country music festival and wounding hundreds more, then taking his own life.

On Saturday, the center floor of the Sullivan Arena was filled with vendors and their products for all those interested in buying, selling, or trading their firearms. Everything from machine guns to semi-automatic pistols were on display.

KTVA found only one vendor selling bump stocks at his table, and he adamantly refused to permit any photography of his products.

Wayne Anthony Ross, a past AGCA president and current NRA board member, said he didn't know much about the devices.

"I would think a bump stock would be for somebody who likes to shoot and has a lot of money for ammunition, but doesn't expect a good shot," Ross said.

Last week, U.S Reps. Carlos Curbelo (R-Fla.) and Seth Moulton (D-Mass.) introduced bipartisan legislation to ban the manufacture, sale and use of bump stocks and similar devices.

The NRA has said it supports additional regulations on bump stocks and similar gun accessories, but the organization has proposed the federal Bureau of Alcohol, Tobacco, Firearms and Explosives handle those regulations rather than Congress.
