Saved money yet waited longer
Had to wait 10 days for it to ship due to this virus bs. Although had a relative order from palmetto state and received his well over a week before I did. Product is great, service is eh. Everything worked fine for my lower. Just disappointed with the wait time.

Great buy for the money!
This completed my 6.5 Grendel build. I liked so much, I came back and bought a pistol kit for my 9mm build!
Mikkel Farrar –
Fits poorly
The stock is so loose on the buffer tube. Not sure how it’s even safe.

Mostly great
Most of the parts are holding up great. Grip is standard, buffer and trigger group all working fine. My only complaint is the stock. Feels kinda cheap and has a lot of play.

I bought parts from six different websites while building my last rifle. The parts ordered from BRD were the first to show up at my door. The quality of the stock in my order was better than expected for the cost.

fast…
It is a pretty good set up. I liked how everything shipped and the care put in the packing, but the buffer tube (if you like it to fit in the grove you will need to shave some off or your upper will hit. Another thing is the adjustable stock can get pushed all the way forward and if you do that it will get stuck on the threads and be a little frustrating.
