Frequently Asked Questions

What are the main advantages of the CMMG Dissent rifle?

The CMMG Dissent offers a direct gas impingement system for potentially smoother recoil, a compact action inspired by the AR-180 design allowing for side-folding stocks, and a wide variety of caliber options. It is also significantly more affordable than comparable rifles like the Sig Spear.

How does the CMMG Dissent compare to the Sig Spear?

The Dissent uses a direct gas impingement system, while the Sig Spear uses a short-stroke gas piston. The Dissent is generally more affordable, offers more caliber choices, and features an AR-180 inspired design with a side-folding stock. The Spear is a premium option with a different operating system.

What calibers are available for the CMMG Dissent?

The CMMG Dissent is available in a broad range of calibers, including 7.62x39mm, .300 Blackout, 5.56x45mm NATO, .308 Winchester, and the newer 8.6 Blackout. CMMG also offers other boutique cartridges for this platform.

Can CMMG Dissent uppers be used on standard AR-15 or AR-10 lowers?

Smaller caliber Dissent uppers (like 5.56) can often be pinned to standard mil-spec AR-15 lowers. However, larger frame Dissent uppers (like .308 and 8.6 Blackout) may require modifications to an AR-10 lower for proper fit and function.
