Innovative design, but ultimately fails. impossible install and wrong hardware. - HERA Arms CQR AR-15 Stock System

First off, the wrong size bolt is included. the bolt had large coarse threads, which is clearly not what an AR received is tapped for. I had to cut my original bolt down to get this mounted.
Second, the install was horrible. You need a ball end allen key because the angle of the grip bolt is sharper than the opening of this stock. Seems easy enough to do and I honestly didnt even worry about it until I installed it. I have a full armorers bench with every tool you can think of. Ive buit probably 100 or more rifles in my life and can do it in my sleep. This stock install, however, took me about 4 hours to get one single bolt to line up. I was just about ready to start a product return out of frustration, but I was able to finally get it installed.

As for function, this grip makes it very difficult to operate the mage release and safety selector switch without totally breaking you hold.

I do like how it looks, very pleased with that. Just not sure if its worth the inflated cost and all the hassle involved.
