I purchased this to use with my Magpul CTR stock on my AR. It wedges in the corner where the cam receptacle is and the shape of the stock limits its movement and it can get wedged into the plastic on the stock in an awkward position, It well made. I have been using now for 6 months and it is rock solid as Magpul stuff always are. Just be wary if you are using in on your CTR stock.
Pros: Well made, sturdy, durable
Cons: Doesn't match up with CTR stock to well
