5.56 / .223 Wylde Upper
From: $399
Your 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 it from the beginning. Here’s how it works:
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, the base price includes our shortest handguard option that still covers the gas block. But if you prefer a longer handguard, 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!
Options with ** after the title require a selection to add the upper to your cart.
The base price does not include a bolt carrier group or charging handle. If you already have a BCG in this caliber or have a charging handle that you like, we aren’t going to make you buy another one. You can just select “None” for those components.
NOTE: The 11″ handguards will cover a Carbine length gas system, but not a Mid Length. Other lengths will cover both.

Great components, great guy! I have 2 grendels and 1 5.56 all uppers from Grendel Hunter. I am extremely impressed with the quality of the products and the level of service provided! The turnaround time is superior to anyone else! The attention to detail is superior to anyone else! The accuracy if the 3 uppers I have is under 1/2 MOA at 100 yards! All chambers are on the snug side of tolerance. I suspect that lends to the accuracy I’m getting. I’m so pleased with the performance, I’m in the process of ordering another 5.56!
