Finally...
An 870 stock that can fit shorter armed adults. Lets me grasp the forend at the front where the surefire light pressure switches are, instead of the very back of the forend where I had to hold with the standard 870 butt stock lengths.

Nice after market stock
I purchased this in orange because it stick out like a sore thumb. Easy to see and there is no way to loose it in the woods if i were to lay it down. Easy to install and the length of pull adjustment is a must for short or long arms. Good job Magpul.

Purchased for ability to adjust length easily. It worked perfectly.

BEST ON THE MARKET
So when I was in law enforcement and went through shotgun training they offered us the pistol grip with a collapsible stock like you'd find on the M4 or a traditional buttstock after shooting about 1000 shells through the training splitting it between two different shotguns I absolutely wanted something like this instead of the in four style pistol grip that thing sucks and you're gonna be black and blue from shooting that many shells but just to be honest the recoil pad on a traditional stock is 1000 times better and more comfortable to shoot so I highly recommend the stock I absolutely love it it's on three different shotguns that I have worth every single penny.

Magpul 870 SGA Buttstock
Would not expect anything else from Magpul. Easy to install.( 5 minutes) Great spacers for length of pull. Very satisfied!

Solid replacement buttstock.
I haven't had a chance to use it yet, I'm waiting on a stock adapter for my Beretta 1301. Appears to be very well made, and will add some mass to the1301, which is a very light gun, in addition to improving the already good ergonomics.

Great Stock
Easy to install on my 590A1 SPX. Really appreciate the ease and modularity of the stock, I think it made the shotgun lighter as well. Plus it's Magpul, what's not to love.
5
As good as expected
The only difficult thing about installing this buttstock was trying to jam a large screwdriver through the small holes in my original Remington buttstock cushion to remove it. Installing the Magpul buttstock was very easy. It's rock solid and looks great, but I expect nothing less from Magpul.

Perfect fit
Used for upgrade on Mossberg 500 for better control. Ergonomics of the grip are much better than stock standard. Adjustable length of pull spacers make this even better.
