Hello everyone, bit of an odd question. I recently moved from AL to MD, but left all of my guns and magazines at my parent’s house (where I moved from) due to the confusing laws. Driving everything up is a pain and flying with them would be a headache, so I’m looking at shipping options.

Here’s what I have (roughly 20 firearms total):
• Mostly SXS or O/U shotguns and milsurp rifles
• 1 stripped AR lower
• 1 complete AR lower
• 1 MP5 .22 Rifle
• 4 handguns
• 2 SCT stripped Glock frames
• A bunch of magazines (mostly standard capacities, and 1 drum)
I’m fully able to possess everything in both states and already have my HQL.

My Main questions:
1. What’s the most cost-effective way to ship the long guns, AR lowers/frames, and magazines to myself in MD?
I’ve looked at ShipMyGun. I’ve also considered USPS for the AR lowers and magazines (seems like a gray area from what I’ve read). Any real-world experience or better options?
2. Any recommended FFLs near Gambrills for the handgun transfers?

Appreciate any advice. Thanks!
