    Title says it all, what more can you ask for!! Went shooting last weekend and it preformed perfect, accurate at 100 yards (limited to range distance) and I,m sure further out. Makes for a great looking gun!

    This upper has great fit and finish, it’s built rock solid. I’ve put close to 10k rounds through it no issues what so ever. Everytime I’m at the range everyone wants to come over and check it out and shoot it. You can’t beat this upper!

    I had a problem with the function and George took care of it and resolved the problem making sure I was satisfied. You can tell he had a genuine desire to exceed the expectation of the customer.

    Received this upper and matched it up with a lower from PSA. Looks great and fit tight. Took it to the range and put about 150 rounds down range. The upper worked flawlessly. This upper is built very well, looks great, and works perfect. Like the fact that the barrel is chambered 223 wylde. Would like to thank Chris for doing a great job helping me. Can not wait to get the ar 10 Upper I have on order.

    I purchased this CBC upper before Christmas and I can hardly wait to assemble it. This is my first build EVER, so I’m really excited.
