A15-M 12.7x42 Beowulf Complete Upper

So the wait is excruciating, but worth it. I will say that the support from the Atheris team is amazing. They let you know where your purchase is as far as the build. when the upper finally arrived I was in complete awwwwwwww. It has an amazing finish and the stainless barrel and NiB BCG really makes it stand out. Love the product and will purchase another when supplies become more available. I can say they don’t sacrifice quality which is why it takes so long. Great job Atheris

All of the pieces to this look and feel to great quality, everyone loves shooting this after the basic .223, I will be buying another upper or whole firearm from them in the near future!

it's a blast to shoot.

Wonderful craftsmanship overall it is a beautiful upper receiver! Very pleased with the purchase!

Any thing gun nowadays is in high demand or not available . This is one beautiful piece of hardware and being Custom Made is above what I expected . Thank You Atheris Rifle Co. Watch for my repeat business !

Well worth the wait to recieve my order. Top quality parts and workmanship. Shoots better than most AR uppers I now own. Price is right and will definitely order in the future. A+

Product is great. Please be patient with these guys the whole industry is backed up from high demand right now.

Worth the wait. Combined this upper with a mil spec lower with an Armaspec H2 stealth recoil buffer and Adaptive Tactical EX stock with a nice recoil pad. 1st time out it performed flawlessly. Shot it without a muzzle brake and it kicks like a mule. Will have to install the muzzle brake before I shoot it again. It definitely gets peoples attention at the gun range. Looks good, shoots good and cycles perfectly.

Well built, shoots well. The only con would be the wait of 4 months to get, but in todays supply chain disrupted world and the number of guns that are being bought I can understand the delay. In the end, it was worth it.

I recently received my 12.7 upper and paired it with a custom lower and simple vortex scope that I eyeballed on install. The wait was excruciating but worth every second. Every shot was perfectly consistent. But. I used cheap magazines and had a 70% feed rate. This is a premium product that operates amazingly, with the right equipment. Switched mags and this is one of the smoothest operating rifles I've ever used. Don't cheap out and you won't be disappointed. Amazing craftsmanship. Great product.

Great upper will definitely buy from them again

Very well made! I have not yet gotten to the range for a full test, but it fits my Ruger AR 556 MPR lower like a glove, as expected. Beautiful stainless barrel, surrounded by top-quality components, and the price is unbeatable. With the current trends in demand and shortages, it took a very long time to receive it, but the communication was good and courteous when I would inquire about it. Worth the wait.
