This airsoft fart flap is the perfect accessory for your Mk23 or any sized airsoft rifle. Designed specifically for the Mk23 but can be made to any size, this flap is made of high-quality rubberized material to ensure maximum performance. It is easy to install, providing a quieter shot by up to 10% (last pic). It has been tried and tested with no effect on range or distance due to the product being printed with dimensional accuracy. For custom sizes, please contact me with the internal measurement you need. For anything over 35mm, please see the separate listing.
