Very well made
Feels very "beefy" probably due to higher quality of aluminum. This is true millspec buffer tube, magpul stock fits very well and tight. I wish I came across this product earlier for my builds. Color is not black , so if you looking for perfect color match with your reciever you won't be pleased. But where I reside fixed stocks only allowed so it doesn't matter. Great product.
