Pat's Pawn & Gun on 441 in Leesburg.

Join the VSS Club.
 

I would suggest that he join the Villages Straight Shooters Club -
Home - where he can meet like minded fellow Villagers, both men and women. If not buyers, he'll get plenty of information, and "advice."

They also have their own classified section on the VSS website.
Classified

Try gunbroker online. It’s an auction site with good bids/prices.
(It’s a good place to calculate the probable value)
Let them worry about state & federal restrictions.
As others said, a shooting club or gun range will usually have a classified ad area for members. Do a bill of sale consistent with federal & state law (buyer has no felonies, no drug charges, etc. Run a background check)
Also check for any gun shows & gun stores would probably purchase for resale but at lower price.

The best advice to the OP on this sight , talk to people who know.!

Gun shows

Marion Market has gun dealers, so I would try there.

This is true, with the following additions:

1. The buyer and seller must both be residents of Florida. Any firearm sale to a non-Florida resident must go through an FFL dealer.

2. For a handgun sale, the buyer must be at least 21 years old. For a long gun, the buyer must be at least 18 years old.

Always keep a copy of the bill of sale, showing complete information on both buyer and seller, including Florida driver's license number; the date of sale; and a description of the firearm, including serial number. The BOS will be your proof of transfer should the firearm ever turn up at a crime scene after you sold it.

Would be interested in seeing a list of what he has if he is so inclined. 3196314698

He could join The Villages Straight Shooters for $25 a year. They have a website to sell or purchase firearms and they also have some great club activities.

Why not try the Villages Straight Shooters Gun club? They have a web page with a classified section. Home

There is a place on the home page to ask questions to the gun gurus. They can help. There is also a Bill of Sale you can down load.

Shooters World, Pawn shops etc will give you 50% or less of the guns value. They're a business and what to make as much as possible off the sales. It's much better to sell them yourself. I recently help a lady sell 15 guns after she lost her husband. Send me a pm if you have question on how to do this.

Gun shop
 

From my sister in Lake City

Saw this on TOTV today.
I can’t respond. Would you or Tom let them know there is a reputable gun shop in Groveland. Matt will help them out. Name of the store is Firebase Tactical 352-429-2423

Pawn shops are FFL's and are safer than selling to a private party.

Florida Statute §790.065 - You must be 21 to purchase ANY firearm in Florida. You are partly correct.

Have them contact the Villages Straight Shooters club and they might be able to help. The can also go to Shooter’s World or any area Pawn Shop. Be sure they get a receipt and ID if they sell privately.
