Mossberg 590A1 18.5" 7-Shot, Threaded for Chokes!

Mossberg 590A1 for sale. 

18.5" model with Ghost Ring Sites.  An S&J Hardware +2 magazine extension is installed for a total of 7 rounds. Original magazine cap and spring included as well.

Barrel threaded for chokes by my local gunsmith. Makes for a more versatile shotgun if you plan to use birdshot. Uses Win-Choke/Accu-Chokes. One Modified sized choke included. 

Bought eight years ago and am least the second owner. ~1000-2000 rounds through it of all types of shot. Been using it as my 3-Gun shotgun and runs flawlessly. Selling as looking to upgrade to a more competition-style shotgun.

Asking $900 plus shipping. 

Will consider trades for a Benelli Nova Speed, a Beretta 1301 Tactical or a Mossberg 590A1 14".

Thank you for looking!
