Your 6.5 Grendel Upper. Your Way.

Grendel Hunter uppers are highly customizable. You aren’t stuck buying components that you’re just going to change out once you receive it. Get it built how you want from the beginning. Here’s how:

Using the options below, select the components you’d like used in your upper. The base price includes components for a base model. For example, a Mil-Spec charging handle is included in the base price, but if you want one that’s ambidextrous, you can upgrade it for a little bit more. The grand total at the bottom of the builder will update with each selection. Get started on your upper build below!

*The base price does not include a bolt carrier group. If you, like many of our customers, already have a Grendel/ARC BCG, we aren’t going to make you buy another one. You can just select “None” for that component.

    I received this upper yesterday and went to the range today. Put more than 50 rounds through it. Three different manufacturers of ammo. No hangups, no issues. Worked perfectly. Easily got 1″ MOA. Very pleased.

    Still breaking her in and put about 82 rounds of various types of 123 grains to see what the barrel likes. The results excellent and MOA @200 yds and all in the 10 ring with a lot of Xโ€™s. Just a slight issue on initial charging from left-side of mag. But runs smooth, cycles just fine while firing. They are right about the recoil being half of a .308 Win. Been wanting one in 22โ€ for several months now, spending a lot of time researching and always coming back the Grendel Hunter and not disappointed. Configured a lower rigged for long range shooting and now I have the right upper. Do recommend as all components were well built and finishedโ€ฆ

    This is a great upper. I like that you get the option to configure it yourself. You get to add the things that you would upgrade later, thus saving money in the long run.

    The 18โ€ barrel was shooting moa groups out of the box even before the barrel was broke in with factory ammo. Once I get a custom load worked up, it should be a real nice shooter.
    Ammo feeds reliably every time. I didnโ€™t have to adjust the gas block at all. The brass was ejecting at the 3:30 position with 3 different loads. Great product.

    I got the 16″ fluted barrel with the upper. The photos do not do this upper any justice. In reality, it’s a great looking unit. I was afraid that the tungsten color would turn out bluish based on the photos but it’s definitely more on the gray / titanium side which is what I rolled the dice on. The handguard looks aggressive with that unique angle cut and the fluted barrel is great looking as well as reducing the overall weight of the upper. I am so glad I got the tungsten instead of black or FDE color – it just stands out and guys keep on doing double takes at it. I hope to complete the build soon and very excited for next deer season!

    I absolutely love my 6.5 Grendel upper I received from GrendalHunter! The quality is very well made and it shoots so good. I was shooting same hole at 100 yards and had no issues. I would definitely recommend GrendelHunter to anyone
