Why Choose the Bear Creek Arsenal Side Charging Upper

This side charging upper eliminates the standard rear charging handle, moving the primary charging function to the left side of the receiver. For California-compliant builds, this can be a significant advantage. When configuring a featureless rifle, a side charger paired with a fixed stock and no pistol grip or vertical foregrip can create a more ergonomic and intuitive manual of arms. It also provides a clear alternative for builders who prefer not to use a rear charging handle with a bullet button or other fixed magazine solution.

The non-reciprocating design means the charging handle remains stationary during firing, increasing safety and preventing interference with optics or accessories. The robust 7075-T6 aluminum construction ensures durability, while the side charging mechanism is a simple, reliable system that reduces points of potential failure compared to more complex alternatives. This Bear Creek upper is a functional component for a serious compliance-focused build.

Frequently Asked Questions

Q: Is this Bear Creek Arsenal upper considered a firearm?
A: No. This is an unfinished receiver component. It is not a firearm and can be shipped directly to your door. A serialized lower receiver, purchased through a California FFL with a DROS and 10-day waiting period, is required to complete the rifle.

Q: Can I use this to build a featureless rifle in California?
A: Yes, this side charging upper is commonly used in featureless builds. You must pair it with a featureless lower configuration—such as a fixed stock and a featureless grip—and ensure the overall rifle meets all other CA requirements, including an overall length of 30 inches or more.

Q: Does the charging handle move when firing?
A: No. This is a non-reciprocating side charging system. The handle is only used to manually charge the rifle and does not move during the firing cycle.
