I just ordered mine also. Birthday coming up!
Remington does have everything in stock for the 20ga Shurshot. Might want to order it now for next turkey season as I couldn't get one last year. Still only available in Black, the best I could tell.
Stock F306720
Fore end F306351
Longer stock bolt if going from wood to synthetic F402630
$118 with shipping and I hope I ordered everything right
