The Primary Weapons Systems Mk116 Mod 2-M upper receiver in .338 ARC delivers a modern, efficient platform for shooters building a purpose-built intermediate cartridge rifle. This 16.1-inch upper comes configured with a low-signature Force Compensator, keeping your muzzle signature manageable while you maintain control on follow-up shots. Whether you're assembling a precision rifle for hunting, competition, or long-range shooting, the Mk116 Mod 2-M offers the modular flexibility and quality that PWS is known for—without the marketing fluff.
The .338 ARC has earned a dedicated following among hunters and riflemen who want more velocity and energy than 6.5 Creedmoor, with less recoil and expense than .338 Lapua Magnum. Paired with PWS's tight-tolerance engineering and a quality upper receiver, this setup gives you a solid foundation for a capable rifle. The 16.1-inch barrel strikes a practical balance between velocity and handling, especially if you're building a rifle that lives in a truck or spends time in timber as often as it does on a range.
Because this is an upper receiver assembly, you'll need to source your own lower receiver and complete the build according to your local laws and intended use. The Force Compensator is already installed, so you're getting a shooter-ready upper out of the box—just add the lower and you're in business.
| Brand | Primary Weapons Systems |
| Model | Mk116 Mod 2-M |
| Caliber | .338 ARC |
| Barrel Length | 16.1 inches |
| Muzzle Device | Force Compensator (low-signature) |
| Type | Upper Receiver Assembly |
The Mk116 Mod 2-M is built on a standard AR-pattern receiver, so it's compatible with any .338 ARC-capable AR lower. You'll need to source your lower separately and ensure it's configured for .338 ARC if you want to shoot that caliber.
The facts provided do not include details about rail or handguard configuration. Contact Bosque Outdoors directly to confirm what mounting solutions are included or compatible with your specific upper.
The Force Compensator is installed on this upper. For removal, service, or replacement options, check PWS's documentation or reach out to our team.
The .338 ARC is used by hunters seeking more power than 6.5 Creedmoor with moderate recoil. The 16.1-inch barrel length works well for hunting scenarios where you need both velocity and portability. Your choice depends on your intended game and hunting style.
