Laylax First Factory Custom Ambi Mag Catch for Tokyo Marui M4 Standard AEG Series

In fast-paced airsoft skirmishes, shaving seconds off your reload time can keep you in the fight when pushing an objective. The Laylax First Factory Custom Ambi Mag Catch for Tokyo Marui M4 Standard AEG Series eliminates the right-hand bias of standard M4 lower receivers by delivering reliable, ambidextrous magazine control directly at your fingertips.

True Ambidextrous Reload Performance

Standard M4 receivers feature a magazine release button accessible only on the right side of the body, creating an awkward reload process for left-handed operators or right-handed shooters operating off-shoulder around left-hand cover. The Laylax First Factory kit integrates an ergonomic lever on the left side of the receiver body. Pressing this left-side lever directly actuates the main locking arm, dropping your empty magazine instantly without requiring you to break your cheek weld or shift your primary grip.

High-Strength Steel Construction & Tactile Texture

Crafted in Japan from precision-machined steel, this custom magazine catch is built to withstand aggressive mag drops, heavy field use, and high spring tension from loaded mid-cap or high-cap magazines. Both the standard button and the left-side actuation lever feature clean stippling/serrations that provide positive tactile engagement, allowing you to locate and press the release effortlessly by feel alone—even while wearing heavy tactical gloves.

Key Features & Technical Benefits:

• Fully Ambidextrous Control: Release magazines quickly using either your left or right index finger.

• Heavy-Duty Steel Alloy Build: Maximum structural strength prevents bending, stripping, or wearing down under heavy use.

• Tactile Surface Serrations: Provides positive slip-resistant grip for effortless actuation with gloves.

• Faster Reload Transitions: Keeps your primary hand on the grip while executing speed reloads off-hand.

• Direct Drop-In TM Compatibility: Fits Tokyo Marui Standard M4 / M16 V2 AEG receivers and compatible clone platforms.

Installation & Field Guidance

Installing the First Factory Custom Ambi Mag Catch requires basic hand tools and can be completed in minutes. Simply unscrew and remove your original factory magazine catch assembly from the right side of the lower receiver. Align the Laylax central catch shaft through the receiver body, position the left-side lever housing into place, and secure the assembly using the provided mounting hardware and tension spring. Test magazine lockup and drop friction with empty magazines to ensure crisp, drop-free operation.
