Selling Laylax TM MWS hop dial adjuster, in packaging not used. 

Product Description:

Recent gas blow back guns are increasingly becoming convenient as models that can perform HOP adjustment from the Ejection port are increasing. 
However, in fact, the ejection port is narrow and it is difficult to work, and some models such as the M4A1 MWS require disassembling every time it is adjusted, and it takes time to fine-tune. This item is a special tool for making HOP adjustments without wearing gloves and without disassembling bolts and slides. 

Compatible models: 
Tokyo Marui Gas Blowback series 
HK 45,  M & P 9 series , P × 4 
USP Compact
