Ok so it's not really a mod, and perhaps it's just fixing a bad habit. I bought this for it to go with a tacstar 6 round side saddle for my 870 defense model. Normally one has to cut off the end of the factory synthetic stock to get it to clear the saddle. This one almost seems designed for it.
It has deep ribbing all the way down, which gives me grip when I have to shuck a round with gloves on in the rain.
The one qualm I had about the Mako is that it comes with two side rails. When I quickly just grab the handguard, my thumb rests against the back of the left rail. Gave me a sore thumb. It's correctable with a hex wrench, just remove that side rail and it works like a charm. The other one I use for attachments. Highly recommended.
Pros: Goes well with the synthetic stock and matte black finish, Fits with no mods, shortens foregrip enough to use a side saddle
Cons: Needs a quick mod to be useful.
