A15-M Billet 6.5 Grendel Complete Upper

THIS UPPER IS JUST WHAT I WAS LOOKING FOR VERY NICE LOOK, CLEAN BUILD. I WAS DEFIANTLY WORHT THE WAIT. SHOOTS GREATS

Took it in subzero temps here in iowa. Shoots operates good. Was getting good accuracy right off the bat. Should only get better

Great quality and craftsmanship. Fit on my lower perfectly. Already has my thermal on it and ready for Texas hog hunt.

I could not be happier with my upper as well as the customer support I received from Kyra on the sales team. She told me it was going to be about a 6 week turn around to get my upper. I told her I had a coyote hunt coming up in 4 weeks and if there was anyway I might could get it by then. KYRA MADE IT HAPPEN with my rifle arriving about 24 days later. Just enough time to sight it in ( tack driver btw) and bring on the hunt. Ended up bagging 9 yotes. Im am very pleased with the quality and accuracy of the rifles as it functioned flawlessly and shot .31 moa with Hornaday black 140 gr BTHP. Top notch company, rifle and customer service!

Very good upper. Shot half inch group at 100 yds. In the first outing.

First day on range, Hornady 123 set, 40 rds had me sighted in, comfortable, and even tested out at 200 yd range, 1 moa!!Very happy! Great piece of equipment !!!! Only wish it had come with brake instead of flash hider!

Fit and finish are great. Everything is tight and put together correctly. Bcg is staked properly. I have not had a chance to fire it yet as I’m waiting on a new scope and muzzle brake. Will update review once I use her a bit but so far so good

I wanted a 20”upper in 6.5 grendel with two different cerakote colors. I received not only exactly what I wanted but I received in my opinion an excellent product. The lead times were long but with everything going on with supply lines, I couldn’t put the blame on Atheris. All in all…well worth the wait and now trying to decide on what upper I want to buy next.

By far the most accurate AR I’ve ever shot or owned. Bought this spring finally got a chance to shoot and wow what a surprise. After sighting in was touching groups at 100 then 200. Moved out to 300 and was consistently shooting sub .25 moa. After 100rds .5 was my worst group! And that was clearly user error!!! Best was .1 moa @ 300. Shooting from a stand about 12’. soon as winter is over and can get a better angle beneath branches I am very excited to go out 5-700yds and see how it performs. Paired with a UIC lower 2 stage trigger and Diamondback 6-24x50.

Verry nice upper top notch for the money . Would highly recommend

Purchased this 6.5 Grendel upper in 22" Fluted with TBox Brake. In one work "Beautiful" . The craftmanship was great and it shoots MOA and Sub MOA with Hdy 123 SST. However with my reloads I have had 6 touching in a 10 round test. I'm still working on my load development but this upper shoots great. I have had a few round not cycle but that was with factory ammo and the first few reloads, that is fxable with gas block adj. Overall a great upper.

DEFINITELY A QUALITY PIECE! WOULD HAVE GIVEN 5 STARS IF IT CAME WITH A BARREL CAP NUT INSTEAD OF A PLASTIC BARREL END CAP. DEFINITELY A GOOD CHOICE FOR ANYONE WANTING A WELL THOUGHT OUT 6.5 GRENDEL UPPER.
