GHK AK Airsoft buffer

Here are two buffers for the GHK AK v2 series of rifles, there is a +3mm and +6mm version (WILL NOT WORK IN THE V3 MODELS). I have tested them and the +6mm version has noticeably increased the rate of fire and improved gas efficiency. Tested with bambu tpu for ams, best if printed out of any tpu, have fun printing!
