Speed Airsoft have released performance upgrades for the M4/M16:
SPEED Airsoft new Magazine Catch Button eliminates the need to depress the button into the receiver in order to remove the magazine catch from the other side of the receiver. Without the SPEED Magazine Catch Button, you will always risk scratching up the receiver every time you need to remove the magazine catch.
The SPEED Airsoft Magazine Catch Button installs and removes in seconds without depressing the button. A special rotating inner ring within the button quickly threads the button onto the magazine catch with the aid of a special SPEED tool, which is included.
This is a great upgrade for those who spend a lot of time tuning and fear marking up the receiver every time they have to remove the magazine catch.
The SPEED Airsoft Magazine Catch Button is available in a kit that includes the special SPEED tool. Owners with multiple M4 and M16 can purchase more buttons by themselves. The SPEED Airsoft Magazine Catch Buttons are available in black to maintain realism and silver for those who want the custom look.
The SPEED Magazine Catch Buttons are in-house CNC machined from USA grade billet aluminum by SPEED Airsoft in Canada. All buttons are anodized for durability.
All SPEED Airsoft products are available through your favorite airsoft dealers worldwide.
