CAA Remington 870 / Mossberg 500 Stock and Forend
Command Arms Accessories have developed a new Remington 870 and Mossberg 500 stock and forend.
The stock features a collapsible M4-style stock, pistol grip, aluminum buffer tube and picatinny rails for optics. There also appears to be a rail on the side of the stock, although I am not sure what could be attached there.

The new forend features a lower rail, which could be used to mount a forward handgrip, and side rails for lights or lasers. I like the grip design.
CAA are selling the stock for $199.99 and the forend for $59.99. Mossberg kit here, Remington kit here.

The rail on the side of the stock is for attaching of the adjustable cheek piece.
I’d like it better if that forend side rail was molded in and they smoothed out the rest. I wouldn’t look forward to spending a day training with that cheese grater.
Isn’t that photo of a Mossberg?
holy cow is the trigger seriously that far away from the grip?
Will, well spotted! They had the photo on the rem page, but it turns out the kit is available for both the 500 and 870. I have updated the page,
Yeah that looks awful to shoot. Good spot on the trigger!
The stock rails are for a spare AR mag, although I have rarely seen that part for sale
I’d think you could put on some sort of extra shell carrier, that wasn’t made of nylon webbing…
I admit that I don’t own a Mossberg 500 (yet), but isn’t the safety on the top-back of the receiver? Exactly under that area that’s now covered with polymer … how does that work?

You are right about the position of the safety on the Mossberg. I doubt the new pistol grip stock blocks the safety, just for reasons of product liability.
But even so, a pistol grip stock places the hand in an extremely inconvenient position for using the Mossberg safety. For that reason alone I wouldn’t use such a stock on a Mossberg.
On the other hand the Mossberg safety is very convenient to use with a conventional stock and is easily observed to verify safe condition.
They should make something like that for Rem 700s (something you can put AR grips and buttstocks on).
