"Excellent quality, large space. No wobble. I use it to hold a 1500ma 70c battery and a custom mosfet/arduino so you can fit basically anything in this.

"Valken makes some great stuff all around and this stock is no exception! Fits very tight onto my standard buffer tube but that's a great thing because it has virtually no wiggle at all. This does not affect adjustment of the stock! The battery space is just as it is advertised, enormous. Fits stick type, butteryfly type, and PEQ type batteries! 10/10 great stock!

"I love this stock!
I got this because I didn’t like the stock that came with my Black Rain Ordinance (King Arms I believe?). I didn’t like how I had to slide it and I didn’t like needing a hex to open it for the battery.
With this one, every issue I’ve had is fixed! The stock has such a nice, tight fit that it doesn’t wobble and it barely, barely, BARELY moves forward/backward. I love the battery space - I have room for my brick AND for a crane/butterfly/nunchunk/buffer tube battery.
We’ll see how the plastic holds up. It doesn’t feel as durable as the stock before it, but time will tell!

"Hands down my favorite stock of all time. First of all, it just looks awesome on any gun. I have put this on an MP5, M4. and shotgun and it just makes the gun become 10x more savage. I just love the design and the quality of the build. Made of excellent materials, has no wobble on my buffer tube, and can take a serious beating. I have used this stock for about a year now and it still looks like its in perfect condition. No breaks, cracks, or failures in any way.
The stock itself has a ton of internal space and can easily fit several batteries depending on the type. I can usually fit 2-3 small stick type 11.1v lipos in there for long operations. The adjusting lever is also designed very well. It has a small switch on it that allows the lever to be "locked" so the stock cannot accidentally be slid all the way off the buffer tube during hectic engagements when you are adjusting your stock.
Overall, its a perfect addition to any gun that uses a standard buffer tube. Absolutely worth the price. You wont be disappointed.

"The Valken ATS polymer M4 stock is a good stock overall, the reason why I am giving it four stars is because it didn�t quite suit my needs. I have an 11.1 volt lipo block style battery and needed a stock that would fit it. There�s a compartment of sorts inside the stock itself but with the way it was made I could not fit the battery inside. I optimized it by taking sheers to the compartment and now the battery fits. Other than that the stock is great! It fit on my elite force 4crl perfectly and is easy to take off the buffer tube. I don�t have to push on a tiny pin to get the stock off the buffer tube, instead I just have to clasp the lever more firmly. The battery compartment is easy to access and the material the stock is made out of is high quality. The stock is made mainly for butterfly style batteries but you can make it work for the 11.1 volt block style batteries as well. Other than that it�s a great stock!
