    So I bought several of these stocks at one time no regrets at all. They’re actually very nice seem to be very solid and well-built no disappointment here I recommended several of my friends after I bought mine and buy their own. They also commented how nice they really were.

    Not bad

    Overall it works as expected having the adjustable cheek rest is a plus. But………. Understand that with the cheek rest down it will impede the charging handle while it’s cycling. You will have to ensure you move your stock back enough to avoid charging handle hitting it. It’s really wobbly…… there is a lot of movement at the stock, it might be less with a commercial buffer tube. But in the end the price point and reliable adjustability it provides is pretty good. The wobble didn’t impact my shots and being mindful of the charging handle cheek rest wasn’t enough to make me feel like the purchase wasn’t worth it.

    At this price point nothing can compare with this stock. It's sturdy, has storage, nice firm rubber butt plate, and actually had a decent adjustable cheek rest. I know most cheek rests are garbage on M4 stocks but this one works. I bought 4 I'm going to be buying 4 more for the future. These rock at this price!!!
