This guide details how to mitigate trigger slap on the CMMG Dissent 9mm by replacing the factory drop-in trigger with a standard mil-spec trigger, like the BCM PNT. The process involves disassembling the lower receiver's fire control group and carefully reinstalling components. This modification is recommended for defensive use where a faster cycling action might otherwise outrun a lighter trigger.

Quick Summary

The CMMG Dissent 9mm features a buffer-less Radial Delayed Blowback system, allowing for compact PDW configurations. However, its fast cycling can cause trigger slap. This can be addressed by replacing the factory trigger with a standard mil-spec trigger, like the BCM PNT, for improved reliability in defensive scenarios.

Frequently Asked Questions

What is trigger slap on the CMMG Dissent 9mm?

Trigger slap on the CMMG Dissent 9mm occurs due to its fast-cycling, buffer-less action. The rapid movement can cause the hammer to follow the bolt carrier group forward, resulting in an audible and tactile sensation that can be undesirable for defensive use.

How can trigger slap be fixed on the CMMG Dissent 9mm?

Trigger slap can be mitigated by replacing the factory drop-in trigger with a standard mil-spec trigger, such as the BCM PNT. This provides a slightly heavier pull and more distinct reset, helping to prevent the hammer from following the bolt carrier group.

What are the magazine compatibility options for the CMMG Dissent 9mm upper?

The CMMG Dissent 9mm upper is versatile, supporting standard AR-15 lowers with conversion inserts like Mean Arms EndoMag, or dedicated lowers designed for Glock, Sig P320, or FN 5.7 magazines.

What is the advantage of the CMMG Dissent's buffer-less design?

The buffer-less design, with all recoil components housed in the upper receiver, allows the CMMG Dissent to utilize compact upper receivers and enables the use of folding stocks or braces, making it a highly adaptable PDW platform.
