Crappy pics but here you go - The Black Aces isn't cut down/new pad yet - I just talked to Limbsaver, the gunsmith is away all month so I'll send it over to him in March when he gets back
M500 furniture is not 100% match but close enough to where I'll refinish them together someday, but the retro forends were getting impossible to find a few years back (and Mossberg doesn't sell the Retrograde furniture separate now) - same with the 870, the forend is a touch lighter so someday I'll likely get the forend refinished to match the stock
The Mossberg and Remington are both fitted with low profile grind to fits - the Remington stock is actually going back to Limbsaver to get another 3/4" chopped off the stock - the trigger placement is different on the Remington so it just changes where I rest my shooting hand but the stock itself is physically longer and it is actually noticeable as I am used to being closer and more 'choked up' on the Mossbergs since the stock is shorter in total length -
