The rifle includes the Tula grip, and the US palm grip.
Esquire, there are a couple of things regarding the auction that will almost certainly cost you money. First, you should have made it a 14 day auction instead of a 7 day auction. It's a thin market, so you'll want to make sure everyone possible sees it. Second, you should do a 50/50 payment. 50/50 is where the buyer pays 50% at the time of the auction close and then 50% at the time the stamp is approved to their NFA dealer. This gives the buyer confidence that you'll successfully complete the transaction. For some reason, the auction pictures are not showing for me. Perhaps that's because it's new. I think it would be good if you'd mention how the rifle is finished. And again, I'd take new pictures with the original factory grip on the rifle. Potential buyers want to feel that it's real and the US Palm grip is a distraction in that regard.
Rights are inherent. They do not come from another's wallet.
