This orange plastic nut installs nicely in place of your original muzzle nut which can be handy for transporting your blank fire BFONG to and from events. Its a nice little touch which helps to avoid at least some awkward questions and may even help prevent you becoming embroiled in a chaotic scene should the wrong people lay eyes on your reenactment load out. The set includes 2 orange nuts. Luckily, the STG has a handy little butt-hole to store your original nut in while you have the orange one installed.
These nuts are threaded to match accurately reproduced BFONGS with M14X1 threads which is the same as original MP44's. The nuts are 3D printed and chased with a tap to ensure the threads are accurate. Do not fire your weapon with the orange nut attached, excessive heat may cause it to melt.
