A15-M 12.7x42 Beowulf Complete Upper

This upper was worth the wait. I have wanted to complete a dedicated .50 beowulf build since 2006 and finally took the leap, and I'm glad I went with an atheris upper. I have the upper paired with a beautiful JL Billet skeltor lower and the and the fitment was excellent and the finish matched very well. A perfect combo for a caliber that demands respect. The components of the entire upper assembly appear premium in quality, including the very nice Mlock handguard. I now have one of my dream guns, looking great and ready to rock and roll. If you are here looking at this review stop now add to cart and check out. You won't be sorry... this upper is better than any offering I've seen from alexander arms directly and at a lesser cost- without sacrifice. They also guarantee 1 moa at 100 yds. That's a claim they stand behind apparently, and not something anyone else can promise for this cartridge.

Magnificent 50 Beowulf Upper, cycled flawlessly, good quality, & built. Very detailed upper, Thank-you Zach & Atheris Team. As I was getting prepared in my lane at the Range, I could hear everyone talking in the background; after 1st shot down Range it seemed like everyone stop shooting at the range & focused all their attention on the Beowulf. That's when all questions started

This upper came out better than i could have imagined! Functions very well! I love all my atheris uppers!

Fit and finish is amazing. The charging handle was a little gritty but once it was oiled it was smooth. High quality.

Appears to be very well built and good quality.

I ORDERED THIS UPPER BACK IN AUGUST AND I HAVE BEEN NOTHING BUT PLEASED WITH IT. SUPERB QUALITY , AND A ROCK SOLID BUILD! THE UPPER WAS ADVERTISED WITH LESS THAN A MINUT ACCURACY AND IT DEFFINATELY HOLD UP ITS END OF THE BARGAIN. THANK YOU ZACH I CANT WAIT FOR MY NEXT BUILD.AWESOME UPPER , AGAIN THANK YOU

all in all very good look, built good

Absolutely great upper to add to my AR collection. Now I can say I own a 50 Cal! .50 Beowulf packs a mean punch and is a hoot to shoot!!

Great looking and shooting upper! The guys at Atheris rifle company are second to none. They built my upper and shipped it to me in 2 weeks when they had a 6-9 week lead time! If your looking for great products for great prices then these guys are your answer

Looks good so far haven't fired it yet

Most fun I have had shooting in years. Amazing quality!

Took quite some time to receive (due to forced covid shutdowns etc) but I was in constant contact with owner of company (which never happens). I mated it with a palmetto lower with rise trigger. I could not be more impressed with the performance of this upper, it is dead nuts accurate at the distances I've been shooting (20 to 60 yards, using just a sitemark red dot). The recoil is very manageable with the break, about like 12g buckshot or a little less. If any of you are looking for a ridiculously well made ar platform firearm plz look at atheris. Great company, and I assure you the owner will attest I'm not easy to deal with.
