I fully recommend the Airidus Industries QD Carrier System. It is by far the best way to carry ammo on your shotgun. I have it and absolutley love it and wouldnt trade it for any other setup.

 

Those look like sweet side saddle, but they’re a little out of my budget. I went with a Mesa aluminum saddle in the $40-50 price point.

ill be doing tophe complete install/swap tomorrow, so pics will be forthcoming.

 

Here's the new fore grip and side saddle.

 

Looks good! Congrats on the pick up. Only thing I'd add is a sling

 

I have Mesa tactical side saddle but decided to remove it. First concern was extra weight of a side saddle and shells on the receiver. I have flashlight installed as well and it’s already heavy enough as it is, considering receiver is steel and not aluminum.

I decided to go with combat belt holding 26 shells instead. As easy if not faster to reload for me as I have Magpul stock. Secondly because I’d like to treat the receiver for rust protection more often and don’t want to unscrew the whole thing every time. If not treated underneath, express tactical models (which mine is) it tends to rust in that area. And thirdly Mesa Tactical recommends to not leave the shells in and remove for the night as the rubber strip holding them will wear out and stop holding the shells. Which sounds as pure nonsense for a side saddle if you ask me

 

Those are some good points to consider.

 

Just to share what I’ve added to my 870 Express Tactical:

Oversized safety
Milled extractor
Mag tube cap with QD mount
Red dot mount plate and red dot

and flashlight

 

Red dot mount plate and red dot

Can you please tell the make/model of both the mount plate and the red dot?

 

Looks good

 

I will be replacing the forend light with a standard Magpul MLock version

Something to consider... The forend light (Surfire) is pretty heavy. You might think that is a negative, and if you are carrying your shotgun all day for hunting, it certainly is. But for Tactical or home defense use, the extra weight absorbs (cancels) some recoil energy.
