Excellent for break-up camo
Excellent fit, easy to install.Solid black gun leaves a black hole in night operations.Mix of colors breaks up solid pattern.Adjustable pull length a definite accessory to adjust when wearing different clothing/gear.Perfect sight alignment when using just front sight bead with the option (separate purchase) to adjust when using other sighting systems.

There are some issues
First I would like to say that I like this stock because the pistol grip is very comfortable and gives you great control of the shotgun.Very easy to set the perfect length of pull.There are some things that Magpul should address.On a Mossberg shotgun this stock prevents you from removing the trigger group without loosening the stock.This is not acceptable so I took my handy dandy Dremmel tool with a small sanding drum (fine) and relieved the area so that the trigger group can now be removed ...Read more

Anyone know if this will replace the grip on a Remington 870 Tac14? Not a huge fan of the shorty grip on the Tac14. Wanted to place this stock on it to keep it “traditional”. Thanks!
