A15-M 6.5 Grendel Complete Upper

Absolutely love it thanks The quality is superior.

I have only been able to shoot one day due to working constantly no days off, I completed the barrel break in with box Hornaday BLACK 123 match ammo. So far even after three to four shot’s I noticed the gun tightened up the group. Craftsman ship is absolutely beautiful and flawless with seems, gas block stakes, BCG and everything else is amazing for the price. I am extremely confident with hand loads I will get very close to 1/2 MOA. Just breaking in barrel I saw factory ammo group approaching MOA. ( The reason I didn’t get MOA was operator error. )With Vortex Viper 5-25 it’s still under 10 lbs with 25 rd mag. Extremely well balanced for 22 inches of barrel. Overall I will definitely be getting another upper if not entire rifle from them again. I sent a email to them to thank them for all the great customer service and quality product that I received. I almost never write reviews for products; but these guys are seriously on top of there game. If you are not sure, contact them. You will see. They small group of dedicated people who will deliver a product easily worth far more $ then you will pay.

22” fluted Grendel shot a .975” group at 300 yards. Well worth the wait!

shoots well and is accurate

They were super transparent about lead times, and answered any questions extremely fast. The upper itself is great quality and very accurate right from installation. Would 100% buy again

Shoots good.

I'm very pleased with the product. Initial groups are great. I shot just over 1" with a crappy collapsible stock with a fixed sling loop at the bottom (not great for riding a sandbag). I switched to my lower with a PRS stock and shot a 5 shot, 5/8" group including one that I called to the right (the other 4 were less then 1/2"). This was with Hornady 123 SSTs.

The wait was not fun, but such is life in the new supply chain reality. First trip out with it and I can't find anything to complain about. Fit and finish are tight, functioned great with no problems.

This thing is amazing. Well worth the wait. Took to the range and last 2 shots at 100 yards could be covered with a dime. Friend of mine got an upper from another dealer and had issues with cycling. I used multiple magazines and never had any failure to pick up or eject issues out of 60 rounds.

This became my favorite rifle on day #1! I haven't bothered to take any of my other rifles out of their cases since I received my Atheris 6.5 Grendel complete upper. It has the tightest grouping at 100 yards that any of my friends have ever seen. I went to our range last week, someone had Installed a 3" steel target at 100 yards. ' because the 6" target became too easy to hit'.

Very impressed with not only how accommodating these folks are they got this out to me really fast now into the hunting season i have switched over to this bad boy Thanks a bunch to the staff at Atheris rifle you guys rock

I had ordered a 24" 6.5G upper several weeks ago and was told it would be shipped in time for a west Texas hog hunt. Time was running out and I was getting nervous. Jody, one of the builders, told me their supplier was behind on 24" barrels but he could build me a 16" barrel and ha e it to me in time to install scope, sight it in and get to the hog hunt and then they would swap it out when the 24" barrels came in. He made it happen and I was able to enjoy the hog hunt. Now just waiting for the 24" barrel. The quality of the upper was astonishingly superb - better than any of my factory built ARs. Anxiously awaiting the finished product. Will do business again!
