So Far So...
Had fun assembling this build kit. Thunder Tactical shipped very quickly. All the parts were there with no issues. Only issue I had was torquing the barrel nut. It broke apart at 50 lbs. I used and Aero precision lower and I can’t wait to shoot it.

.300 quad...
Awesome upper that includes a quad rail which I believe is superior to m- lok. Fit and finish is beautiful.
