 Ambidextrous Side Charging AR Upper Receiver

After overwhelming demand we are bringing back the original GEN 1 Blackwood Arms Ambi Side Charging Upper Receiver.

We run 100 units at a time, these are not the mass production units you see imitated around the internet. Why run only 100 units? We take inspiration from another American Classic, Small Batch Bourbon.  Every upper is hand deburred, Packaged and hand delivered to Anodization. Our 5 step anodization process exceeds all industry standards, we only work with a true Type III Class II finished with our proprietary PTFE coating. From there they are picked up by Blackwood Arms and inspected and then hand finished and assembled.  These are true works of American Pride, Passion with the Commitment to producing the finest Side Charging Upper Receiver in the World. 

Blackwood Arm’s Billet Side-Charging Ambidextrous Upper  is hands down the best upper on the market .  It’s versatility and precision engineering means it’s not only highly function but also adaptable. It’s designed for ambidextrous use which has a wide range of benefits such as; ease of manipulation for 3 Gun & competition shooters,  versatility as a left, right or ambi system, reduced number of moving parts compared to a standard AR 15 Upper receiver.  Increased tolerances for a tight and secure connection to your lower receiver.

The bolt carrier is precision machine from 8620 Cold Roll Steel The Blackwood Billet Side-Charging Ambidextrous Upper is machined from a solid chunk of the highest quality billet  7075 T6 aluminum.  Engineered with the strictest of standards and is the most versatile upper receiver on the market

702 Shooter’s Review 

The Blackwood Arms Side Charging AR-15 Upper Receiver is precision machined from virgin 7075 T6 Billet, hard anodized and topped with a very nice Teflon Finish (as are the charging handles). The bolt carrier is machined from 8620 cold rolled steel. The included 5.56mm bolt is MPI tested and the entire BCG has a Nickel Boron finish. Those specs alone set it apart from the discontinued OPS-4. Blackwood Arms produces these uppers in fairly small batches allowing for better attention to detail which definitely shows in the finished product.

After posting the OPS-4 review, I received a lot of questions and some comments about the reciprocating side charging design. Some people were concerned about the handles backing out. Although this does happen if you hand tighten the handles, if you snug them up a little with an allen wrench, I haven’t had them break free. I really don’t see this as any sort of real concern. Other comments made mention of it not being a “battle proven” upgrade.  OK, I’ll give you that. This is not the gun I would be taking with me when the SHTF. However, lets look at it for what it really is. The Blackwood Arms Side Charging AR-15 Upper Receiver is a specialty item that is best used in speciality situations. In my honest opinion, this upper is a perfect match for a precision bench gun, a varmint gun (I think I’ll build one in a .204 Ruger), for people with a disability who have difficulties with a regular charging handle, or somebody who wants to build a unique rifle or AR pistol.

Blackwood Arms is a small company and the owner Andrew B. BeGole wouldn’t change it. Andrew is dedicated to quality above all else and making small quantities allows him to keep a close eye on the products and ensure he turns out the best product he possibly can using the best materials. Over his many years of machining parts his company has made major parts for some of the very best high dollar AR’s. I can’t really say who they are because of contract restrictions but all of you are familiar with those companies.

    Fell in love with this on sight. I’m building my first 300blk and wanted it to be unique. This definitely does the job! Killer customer service. Andy called personally and had me all set up!

  3. Rated 5 out of 5

    I wish I had ordered 2 of these uppers during the sale.

    This is the highest quality upper [scratch that] AR part I’ve ever purchased. Watch out Noveske,Seekins,Christensen because Blackwood Arms means BUSINESS.

    Thanks again Andy for the upper & the best customer service I’ve ever had.

  4. Rated 4 out of 5

    I have been a LAR Grizzly OPS-4 guy for years. I was saddened when I found out I couldn’t get any them & I found Blackwood Arms.

    I was a sceptic and spoke with Andy at Blackwood Arms and after I was a believer.

    I can’t believe what I’m saying here but the Blackwood Arms upper is much better than the OPS-4. The quality is great and the customer service is great to.

    I will be back.

  5. Rated 3 out of 5

    Exactly what I was looking for in an upper, every bit as good as the OPS-4, Buy I like the handle on this more. Only minor complaint is I like the Crest style logo over the grenade.

    Very clean lines.

    I just want to say I just bought this ambi upper from blackwoods. I was talking to a guy called Andy the entire time. This was the BEST costumer service I could have asked for. I’m new to the side charging upper and didn’t know with an empty mag it locks to the rear. Andy left work drove home to trouble shoot the problem and send me pictures. He soon figured out I was just using an empty mag. I haven’t shot with the upper yet but it looks great and I’m sure if I have any problems Andy would be there to help me trouble shoot. If anyone wants pictures of it on my rifle let me know.

  8. Rated 3 out of 5

    This upper means business Its heavy walled construction and reciprocating bolt handles simplify the action to give me hope for an accurate rifle with all the manipulating abilities of a standard upper
