  1. Rated 4 out of 5


    Purchased this from another retailer and was impressed enough to come over here and write a review. Fitment and build quality are very good to excellent, matched up very nicely to my lower, materials appear to be well made, shoots accurately and reliably with an AIM BCG and Strike Industries CH. I can definitely see another CBC upper in my future. The only reason I dropped it a star was for finish. The barrel is finished well, but the receiver and handguard finish is nice but very thin.

    At first I had my doubts on purchasing this upper, but when it went on sale for $339 with a BCG, charging handle and lifetime warranty I had to gamble. First off the packaging it came from the factory. It came on on regular box, inside that regular box is tube, inside the tube is the upper wrap in bubble wrap, what else can I say about shipping “EXCELLENT”. I was like a little boy opening a present on christmas, I was so excited. Unwrapped it and there it is, a very nice and well built upper. I was still waiting for the lower I was going to pair it with, but I cant wait any longer so I paired it with lower I had. Went to the range and shot it. First round went fine, second round jammed, I had to hit the charging handle with a piece of wood to release it. After firing 20 to 30 rounds it jammed again, I was like what is going on. I contacted CBC Industries and spoke with Lorraine (what a sweet lady) told her what was going on, she ask me to send back the upper and they are going to take a look at it or replace it at no cost to me. The lower and mags I ordered to pair it with came in. Needless to say I paired the two together and shot it. Over 100 round shot and no jam I was like what is going on. Got the old mags I shot it before and found out the mags I was using first was causing it to jam, problem solved. As far as accuracy goes I wish I could post a picture of the shot groupings at 50 yards ‘EXCELLENT SHOT GROUPING”, this will not be my last CBC purchase. THANKS CBC.

    After picking up a complete lower at my local gunshop for $229, I needed an upper and BCG. Quick webseach and I come across CBC industries. $259 bucks later, and about a week and I find myself sitting at the kitchen table unwrapping one of the best deals I’ve come across. Sighted in at sixty years with a cheap scope ( I’ll install better optics soon), the gun shot fine. Looks great, shoots great, price can’t be beat. What more could you ask for? Thanks CBC. I’ll be a return customer for sure.

    Wanted to try a “shortie” on the NRA National Match course. Got this one from CBC, mated it with a spare Armalite lower, mounted a 2-8x Nikon, strapped into a Weller sling, and fired a 477/500 at the local Independence Day 50-shot high power competition. Outstanding performance, reliable functioning, couldn’t ask for more in an upper. Glad I ordered two, just went back and ordered a stainless fluted job. Great value, great product!

    Purchased this a while back just to finish a quick build and I must say I am more than happy with it. Mounted up to an Anderson lower just perfect. Packaging was overkill but that is what makes it top of the list. Edges are a little sharp on the rail but that is not a big deal to me. Used another manufactures CH and BCG and both dropped right in and worked like a charm. Weapon not only looks great for the price but functions great as well. These guys are easy to work with, easy to talk to and respond well and will definitely be getting more of my business.

    I took a chance and bought this complete upper with some apprehension as to CBC Industries quality. After much consideration I decided to go with this upper and was I glad I did! I took it to the range and cycled about 200 rounds of both brass and steel rounds with NO issues! it shot 1.5 inch groups at 100 yards. I couldn’t be happier with CBC Industries I will definitely be buying much more from them in the future!

    Just received my upper today and I’m blown away by the quality and craftsmanship at such an affordable price! Can’t wait to shoot! Will definitely be buying again from CBC in the near future.

    When I received the upper, I was skittish to shoot it as the rail had 2 of 6 bolts loose and rail wasn’t straight. So 2 minutes with an Allen wrench, and after checking everything else to spec (which was perfect), everything was aligned and tight.
    After 120 rounds, I can say it’s a sub MOA rifle, but be sure to lube the feed ramps up well. They’re a little sharp and don’t like cheap ammo at first. I had a few FTF problems initially that were immediately solved with quality lube (not spray like Rem Oil).
    It’s lighter than expected, drives nails, and reliable. I wouldn’t hesitate to buy it again.
    Oh, and the pictures really don’t do this thing justice. It’s a work of art.

    CBC. Thank you for a great deal on a really sweet upper. I wasn’t sure if I would like the new G2 keymod but after holding it and putting some lead down range I’m very impressed. It seems to me to be a nice light upper with heavy duty performance.

    This is a great looking upper
    One glance tells you something different is going on here. I’ve not seen anything like that elsewhere. My compliments to guys that came up with it. Well done!

    The shipping container is well made to ensure your upper arrives at your house in the same condition in which it left the plant.

    More! I need more of these.

    I would have liked to post some pictures of the complete gun but I don’t see how to do that here

    I received my upper about 2 weeks back. Fit and finish were perfect and have sent 500 rounds down range with no malfunctions. The customer service I received was top notch. CBC is a growing company that is experiencing growing pains, but in my dealings with them, they have handled everything in a professional and prompt manner. I have another upper on order that has experienced a delay. When I inquired, Vince called me and couldn’t have handled the situation better. He upgraded my hand guard at no charge to me and offered a sincere apology. I will not hesitate to buy from them again in the future.

    Stay the course guys and God Bless!

    Finally was able to put some rounds through this bad boy after having it for a week or 2 and wow I love it. Super lightweight, feels good in the hand (was concerned because I’ve never been wild about key mod) and is a nail driver! Upper mounted perfectly to my spikes punisher lower, fit and finish are top notch and you can tell quality parts are used for both the upper and BCG. I’ve had several people try to buy it from me in the short time I’ve had it but no way I’m letting this thing go. Can’t comment much on customer service but the 1 call I did make to inquire on my order status went straight to a real person, she was a very nice lady (sorry I can’t remember her name) and she told me mine would be shipping out the following Monday (I called on a Thursday) on Friday I had a tracking number and on Wednesday it was in my hand. Saw the box sticking out of my mailbox when I got out of the shower and almost ran outside in a towel I was so excited. Needless to say I will defiantly be doing business with CBC again when I start my next build and I’m telling everyone I know to check them out. Thanks for a great product at an amazing price! Whatever you are doing keep it up!

    I won’t say what i paid for this little beauty because the last upper i bought went up $40 after i bought it. The barrel is sweet. The rail is keymod heaven and is very stout and the finish is good. Make sure you unscrew the setscrews and loctite them as with any rail you buy. The choice of twist is an added comfort. The floating rail lines up perfectly with the upper rail. I’ve overpaid for barelled uppers before. I received my money’s worth this time…..and with the last pistol upper i bought here. I can also say CBC customer service is responsive. Maybe not lightning fast responsive but they will take care of you. 5 stars

    I’ve wanted an AR for 5+ years and debated buying a complete rifle or building one the whole time. I talked with friends, folks at multiple gun shops, and researched the topic to death, finally deciding that a custom build was right for me. I stumbled across CBC’s website and couldn’t figure out why their receivers looked so great, had positive reviews, and didn’t have the price tag to match. Once I saw that CBC offers a lifetime warranty I decided to give them my business — and man, what a good decision it was! The upper fit my lower perfectly and there wasn’t a single blemish or burr on any of the metals. I did need to reach out to customer service because the package took a little longer to arrive than I anticipated, but all in all they got back to me and it was delivered the same day, about 3-4 weeks after I purchased it. Everything was packaged well and you could tell that CBC takes pride in their product. So far, everyone who’s seen the upper has been impressed with its quality, and after putting the first 100 rounds through it everything seems to running well. I had some feeding issues at first but they weren’t because of CBC’s upper — it was a problem with the BCG that I bought elsewhere. Long story short, I will definitely be a return customer and am already planning the next build. Thanks for building such a great product and making it affordable; I can’t wait to work with you guys again!

    First used, jammed every shot. Bummed out, but then I realized I never lubed it. Sprayed oil into the action and it worked flawlessly. I love the feel and light weight. I am absolutely sold on cbcindustries. Already ordered my third kit in 300 blackout.

    16″ 1 in 8 twist 5.56 upper: The first thing I noticed right away, was how it was packed. In a 1″ thick closed cell foam box. Drop it all you want, no shipping carrier can hurt it. I opened the box and was immediately impressed with the finish, a deep black. Very classy and even. I fitted it to my Bushmaster lower, topped it off with a red dot style sight I had laying around, (very anxious to go shoot this) and fired 200 rounds through it today. Not a hitch. Solid, accurate, affordable, and it looks great too. If you’re thinking about grabbing one of these do yourself a favor and do it. You won’t regret it. These uppers would be a deal at twice the price. ~ Trent

    Definitely the best bang for the buck upper out there. Seems to shoot well. Did notice that the flash hider was on crooked and the front of the hand guard had some dings on it. Still overall pleased, just a bit disappointed in the quality control. It did show up a week earlier than I was expecting also

    My son turned 18 in september , so i decided we would build a rifle for his birthday. I had a couple psa lowers, so i ordered some parts kits and a radical firearms upper. Well radical takes 8 weeks to ship. I was worried it wouldn’t arrive on time so i order from cbc. 8 days to my door. I figured i would give the better upper to my son since i already have a few quality ar’s. Well the cbc hands down was the better upper. Fit and finish was perfect a true black color not ashy gray. Very accurate , it took four shots from fifty yards to zero in with a primary arms 1×4 scope. I am very happy with this purchase and my son absolutely loves it. CBC thanks for providng me with some father /son time and making a quality product. Sincerely Jeff

    I’m totally happy with this upper assembly and would buy again from CBC. The robust thick foam packaging was unexpected, but appreciated.
    Others have commented about a misalignment between the receiver and handguard, but my assembly’s alignment was not much different than other builds I’ve done. The only negative comment is that the handguard edges are sharper than I’d like. These comments are really nit-picky and no reason for concern — especially at the price point.
    During my first outing, I shot 90 issue free rounds. I wasn’t able to confirm accuracy/repeatability because it was during a casual competition and I didn’t have a chance to dial in my scope beforehand. When shooting, the nit-picky comments fade away and the reliability stands out. Only time will tell about long term reliability, but I have no reason for concern.
    CBC is a great example of providing reasonably priced, quality products. Thanks.

    This was my 3rd purchase of a CBC Upper. The 1st 2 were flawless. The 3rd 1 had a small issue so I called and spoke with Vince. I explained the problem. They were able to resolve the issue in 1 phone call. I have not shot the last one, but the other 2 shoot very accurately. The fit and finish is as good if not better than some ideas have seen at twice the price. Great job guys and keep up the great work. Some of my friends are getting ready to purchase from you as well. You now have a customer for life.

    Got this one on special w/BCG and charging handle. It is absolutely beautiful. Very well put together from what I can tell. Mated it to a DPMS lower and it fits well with virtually no play. Haven’t had a chance to take it to the range yet, but if shoots like my other CBC upper I’m expecting great results. I’ll be back.

    I was shopping for a discounted upper to pair with my Aero lower assembly, but I wanted one with the Nitride finish. I was glad I didn’t settle for a different brand. This upper assembly is lightweight and accurate, and I haven’t found any blemishes yet. Functioned perfectly at the range and looks great. I’m happy to support an American company that focuses on employing veterans and offers a lifetime warranty. I will be returning.
