I would wait until you have your new Maverick in your hands and see what they sent you. I've seen them send a small brown envelope with a couple swivel screws in it. Maybe you'll get lucky. Some barrel screws are threaded ,,,,, some aren't.
That is the correct part number.12030.
Keep us posted on what they sent you and how the new Maverick came.
The take down screw has a threaded hole. I ordered 2 studs from Midway and replaced the original screw with the Uncle Mike's that just got here in the mail. It has a set of swivels, screw with front swivel stud, white washer and rear stud, tool to remove retainer and a new retainer. Uncle Mike's number 1810-2. I got this at Amazon for $14. No shipping because I have Prime. But, the studs are $4.99 each at Midway and only $4.99 shipping. Brownells has them same price, but over $7 shipping. If you order them from Mossberg, they are $3 each and 12.+ shipping.
This worked out really well. It would have been nice to save a few bucks but i had a hard time finding these parts. The studs are not Maverick parts and you have to look for them in the accessories list for the 500/50-A1 I believe. or lust search for 12030 part number in the Mossberg search engine.
