Which would mean that nobody in Erie county has an AR pistol. Very doubtful.It seems 300blk is a good choice for a pistol build at Least from what I've read. It seems a good choice for a shorter barrel and already optimized to run on a pistol length gas system.
I definitely feel like I got some bad info, but before this Pandemic I was at a local gun store I won't publicly name here, and asked them about buying a stripped lower as a pistol. They said they won't sell it that way because Erie county won't add it to my permit. They claimed because it won't have a caliber etc that a stripped lower couldn't be added.
