Just two days before Vice President Joe Biden delivers a comprehensive set of recommendations on gun policy, National Rifle Association President David Keene rejected the reported outline of suggestions Sunday and dismissed any ban on assault weapons or high-capacity magazines as a non-starter.

The NRA president predicted a difficult road ahead for those pursuing a ban on assault weapons and said he believed he had enough support to prevent such legislation from passing.

But while an assault weapons ban remains a divisive issue on Capitol Hill, several of its opponents have said they could get behind action on high-capacity magazines. Sen. Chuck Grassley (R-Iowa) called high-capacity magazines "a whole different issue," while Rep. Phil Gingrey (R-Ga.), who has enjoyed a lifetime "A" rating from the NRA, said he would be "willing to listen to the possibility of the capacity of a magazine."
