Mossberg Tri-Rail Attachment

US Import Defender Tactical Tri-Rail adapter for Mossberg Shotguns

Fits over the end of the factory mag tube cap and screwed down with the swivel stud.

Had it on my 590 Retrograde but it's just not the style I want for the gun.

Will include a longer swivel stud required to secure the adapter. My factory stud was too short to thread on so I ordered a longer one for this.

Price is firm, local sale in person only.
