Awesome setup
Just got my upper back from them 2 days ago and took to range today. Gun worked flawlessly. Put about 250 rounds down range not a single problem. Would highly recommend this product. I tell everyone I know about it. Was skeptical at first because i never heard of them and shipping upper to them was kinda a pain but end product is great. Fully understand why they want to install it, because if I did it quality control is gone.

Love it.
I have a low profile piston setup on a midlength 6.8 SPC upper. I'm leaving the review on the 5.56 page because they no longer have the midlength 6.8 listed. I absolutely love it. I have put about 500 rounds through it since I got it back a few weeks ago, and it has functioned flawlessly no matter what kind of ammo I put through it. Their customer service is phenomenal, their products are top notch, and the prices are more than fair. I would rate it a six if I could. I highly recommend their piston systems to anyone looking to upgrade from DI or even building a piston setup from scratch like I did.
