For sale to organize parts. This is a 1-cell body equivalent to SUREFIRE 3P. The head side is compatible with Z44 without any problems, but the screw pitch on the tail side was slightly different from SUREFIRE (only 50-60% could be screwed in), so the threaded part has been modified with a file to allow it to be tightened. Tail switch caps with contacts all around, such as SF Z41 and G2 momentary switches, and aftermarket replica Z41 click-on switches, are not a problem. However, with types that have 3 contact points (Z41 click-on and general click-on switches of the PX series), flickering (instability) occurs when going from half-press to full-press and during continuous illumination. Please refrain from purchasing if you are sensitive or particular about details. No pets. Non-smoking. Shipped via Yu-packet Plus. Shipping cost included: 520 yen. 2700 + 520
