    Quality Service People that make your company GREAT. True to your customers and service minded that’s the other product you are marketing. This upper perfect, shipping container perfect. The BCG you sell, best I have ever seen, it has a finish better than any other’s. This is my second CBC upper, and won’t be my last.

    I bought this recently. Finish is reasonable. It looks like scratches on the barrel where the gas block was installed. But that barrel is a chunk of steel! Super thick at the base where it counts! About three hundred rounds through it. Shooting very nice groups close to one inch but I’m not the greatest either. I ordered mine with a Hera Arms rail. No regrets. Great barrel great rail.

    Finally had the chance to take it out to the range this past week. I have it mounted on a YHM lower with a match grade trigger as well as a rifle length buttstock with a Magpul PRS. I mounted a bipod on front bottom Picatinny spot. This is a very impressive upper. Great BCG and while I’m not the best shot, I was dialed in with 1″ groups at 100 yards and ultimately about 2-3″ at 300 yards. The heavy barrel is a serious slab of steel as already mentioned and is a real plus.

    My only gripe is that the rail “walks.” By that I mean after about a 100 rounds I noted the rail had a gap between the upper receiver and the back of the rail. It was flush when I started. The only thing I can figure is the rail screws aren’t tight enough and the recoil mixed with the bipod staying put more or less acted to pull the rail forward. I’ll get a hold of customer service to make sure I torque it right, but I think that’s all it needs. Certainly not a deal breaker in my book, but enough to earn 4 instead of 5 stars.

    Received my order yesterday and let me just say that this upper is absolutely GORGEOUS!!!!! It came packaged well and no blemishes at all. I was extremely surprised with the quality and the keymaod rail awesome and super slim. Perfect fit to my Spike’s lower. Thanks CBC!!!!!!

    Solid construction, everything looks like great quality BUT!!!!!!!! They do NOT have 1:8 twist as advertised, they ONLY have 1:9. I was disappointed when I got it and contacted them and found out it was either stay with 1:9 or have no rifle. I was really hoping for 1:8(why else would you want a 20″). So I think it’s a great product, but there’s no point in having a 20″ with the 1:9.

    CBC had an overstock sale on this upper. I ordered it at the beginning of the week and I received it today. CBC is an awesome company to deal with. Their customer service is better than any other company I have ever had dealings with. Everyone I have spoken to has been friendly, professional and helpful. This is the forth CBC upper I have purchased. Due to the quality of the products and their people I won’t buy from anyone else. It’s also a very big plus they are Vets. Thank you for your service.

    This upper is solid! After dialing it in I’m getting 1″ groups at 100 yards and putting shots right on top of each other at 50 yards. Good solid construction and a beefy barrel. I’ll be using this for coyotes and competition…

    I couldn’t find any issues with this upper. I have shot groups less than an inch at 100yards with hand loads. I will buy another CBC upper in the future. Thanks:thumbsup:

    Bought this upper on a whim for use on coyotes. Read the reviews and placed the order. Ordered a nickle boron bolt group from AIM to go with it. Upper showed up in 2 weeks and after running a Bore Snake thru the barrel with a liberal coat of oil on everything took it to the range on a cold December day. Ran a 20 rd mag thru it for a short break-in then shot some paper. Surprisingly afer a sight in of my Leupold 3×9 it shot five 5 shot groups less than 1″ and the last one was 5/8″. Im happy with it and would buy another if CBC were to expand into making .224 Valkyrie uppers.
