From: $769.00 Your .450 Bushmaster 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 is for a complete upper, so it includes a bolt carrier group and charging handle. 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 select “None” for that component and you’ll receive a $100 discount at checkout. PLEASE NOTE: The discount will not be reflected in the total at the bottom of this page.
