This upper for my 300 BLK out was awesome! Looks amazing and fits like a glove. Took it to the range and got it dialed in. I’m very impressed. You can just tell it is a quality piece. Further more I called to verify everything I ordered and was and Joe went above and beyond to make sure everything was perfect and I was satisfied with what I ordered. Truly a top notch company!
