Instead of one guest, we have three. They are all members of a new initiative trying to break the decades-old logjam around gun policy. The participants from Bridging the Divide join the show to discuss how their detailed policy proposals differ from the ones our debate has centered around for years.

Dr. Michael Siegel of Tufts University, Rob Pincus of the Second Amendment Organization, and Jonathan Lowy of Global Action on Gun Violence join the show to explain their role in the project. Dr. Siegel provides an overview of the effort, while Pincus and Lowy explain the input they provided and the compromises they reached.

Pincus noted the effort isn't part of a pre-existing gun group and isn't a traditional organization at all. Instead, Siegel said it's a working group that was put together to try to update gun policy with the goal of reducing violent crime while filling the gaps in current policy. He said a big part of achieving that goal involved getting input from gun owners and gun-rights activists in addition to academics and gun-control advocates.

The working group, which went public on Thursday, produced a comprehensive policy plan complete with model legislation. They propose new variations for background checks, extreme risk protection orders, community violence intervention, suicide prevention, firearm prohibitions, dealer regulations, gun storage, and gun injury prevention. All of them have been updated to address some long-running complaints about their effectiveness or their potential to infringe on people's gun rights.

Pincus and Lowy, unlikely bedfellows given that one owns a gun company and the other has made a career of suing them, said they were proud of the work the group has done and felt their input was actually incorporated into the proposals. They both explained what they thought was the best idea in the plan and why they felt it was important for them to be involved.

Siegel admitted the policy proposals are likely to face plenty of criticism, even with the effort to try and address many of the long-standing critiques associated with each of them. He said it would likely be an uphill battle to get the proposals turned into law. But he noted the group included lawmakers as part of the working group, and he said he is confident in their plan to get other legislators on board.

Special Guests: Jonathan Lowy, Michael Siegel, and Rob Pincus.

To figure out what effect all of that might have on the homebuilt gun community, we've got Rob Pincus back on the show. He's a part-owner of a licensed firearms company but also the organizer of the Gun Maker's Match.

He explained what it was like to have a foot in both worlds and explained the evolution of home gun making from the 1990s through today. He said the tech had advanced a great deal over time, but most home builds still require factory-made parts, and he hopes to get the industry more involved in that side of the gun business. However, he admitted this month's high-profile killing is likely to set those efforts back.

Pincus argued the attention is probably going to bring even more scrutiny to 3D-printing guns. That's likely to amplify the fight over homebuilt firearms. Still, Pincus said he doubts it'll lead to new restrictions at the federal, or even the state, level.

Special Guest: Rob Pincus.

That's why we've brought Rob Picus on the show. Rob is one of the key organizers behind the gunmakers match, a shooting competition for people who build their own firearms. He has become engrained in the homebuilding community.

He said companies that make 80 percent frames or receivers have begun to test the new legal landscape. At least one company has made the unserialized and unfinished parts available for sale apart from the jigs and drill bits needed to finish them. Since the ATF rule considers the parts being sold alongside what's required to build them into a working gun the same as selling a working gun, the strategy to remain compliant appears to just be selling everything separately.

Rob said Polymer80, one of the market's biggest companies, is also moving towards selling unfinished receivers on their own. Still, there are a lot of unanswered questions with potentially disastrous consequences for anyone who answers wrong. Rob explains the potential pitfalls.

He also gives his view of the state of the effort to reform the NRA from the inside. Rob is a board member of Save the Second, which was formed to try and oust current NRA leadership and impose new internal controls after accusations of financial impropriety began hounding the gun-rights group. However, he admitted the reform movement has been much less successful than he'd initially hoped as this week's news that dissident board member Philip Journey is not being renominated for this year's ballot by his fellow board members.

Plus, Contributing Writer Jake Fogleman and I discuss how California and New York are pushing back against the Supreme Court's gun-carry ruling.
