The M249S Binary Trigger a civilian iteration of the military’s esteemed M249 light machine gun, boasts an impressive rapid-fire capability that stands out in shooting circles. The key to unlocking the full potential of this semi-automatic firearm lies in its trigger system. Upgrading to an M249S Binary Trigger offers a revolutionary enhancement, catching the eye of firearms enthusiasts worldwide.
A binary trigger system allows for firing not only upon pulling the trigger but also upon releasing it, effectively doubling the rate of fire. This innovative mechanism promises unparalleled responsiveness and a smoother shooting rhythm, making it a game-changer for any shooter. However, upgrading to a binary trigger requires careful consideration of legalities, safety, and suitability for your intended use.
In this comprehensive guide, we delve into the workings of the M249S binary trigger, its benefits, legal considerations, and safety implications to equip you with the knowledge needed for an informed decision.
Understanding Binary Triggers
What is a Binary Trigger?
A binary trigger operates on a binary system, enabling two modes of firing: a shot on the trigger pull and another on its release. This advancement from standard single-action triggers in most semi-automatic firearms offers a unique firing experience.
How Binary Triggers Work
The mechanics of a binary trigger are fascinating:
Semi-Automatic Mode: Functions like any standard semi-automatic firearm.
Binary Mode: Engages a sear on both the pull and release, interacting with the firing mechanism to release the hammer twice – once on the pull and again on the release.
Legal Status of Binary Triggers
While binary triggers are legal at the federal level in the United States, state laws can vary. Always check local firearms regulations before purchasing or installing a binary trigger. As of 2023, binary triggers are not classified as “machine guns” under federal law, thus escaping regulation under the National Firearms Act or the Gun Control Act. However, given the dynamic nature of firearms legislation, ongoing monitoring is essential.
The M249S Trigger System
Standard M249S Trigger Mechanism
The M249S’s stock trigger system is designed for reliability and consistency, closely mirroring its military counterpart, making it ideal for civilian shooters prioritizing dependability.
Benefits of Trigger Upgrades for the M249S
Upgrading the M249S trigger system offers several advantages:
Enhanced Fire Rate: A binary trigger can double the firing rate, mimicking full-auto speed while remaining legally semi-automatic.
Improved Shooting Experience: Adds enjoyment and challenge for competitive shooters and range enthusiasts.
Precision and Control: Provides a more controlled shooting cycle, aiding in rapid-action scenarios.
M249S Binary Trigger Features
Design and Technology Behind the M249S Binary Trigger
Sophisticated Sear Mechanism: Precisely crafted to catch and release the hammer reliably.
Enhanced Springs: Stronger or uniquely tensioned to handle the firing stress.
Dedicated Disconnector: Ensures the hammer is captured after each shot, prepping for the subsequent release fire.
M249S Forced Reset Trigger
Understanding Forced Reset Triggers
A forced reset trigger automatically resets the trigger after each shot, allowing for rapid fire with less manual trigger movement.
Differences Between Binary and Forced Reset Triggers
Firing Sequence: Binary triggers fire on pull and release, while forced reset triggers fire only on pull but reset faster.
Shooting Technique: Forced reset triggers require less finger movement, potentially offering a higher rate of fire with practice.
Upgrading Your M249S Trigger
Assessing Your Needs
Evaluate your shooting goals, skill level, and budget before opting for an M249S trigger upgrade.
Choosing a Trigger Upgrade
When selecting a binary or forced reset trigger, consider:
Reliability and Quality: Look for well-reviewed triggers.
Ease of Installation: Determine if professional assistance is needed.
Compatibility: Ensure the trigger is designed for M249S.
