Runs flawlessly. I have mine on a lower with a vltor a5 buffer tube, kynshot 5007, and a 308 carbine spring with a custom spacer at the back of the tube. Runs really smoothly with great dot return. Ran it at a match last weekend and loved it. Even with just a flash hider it runs smoother and flatter than the compensates Davinci I’ve been running. Would recommend for sure

I put 300 rounds through it over the weekend. It’s on my UDP-9 lower, I simply swapped the current upper for the new 16” upper.
It is performing flawlessly. Not a single FTF or hiccup.
Thanks!
