    "This bolt was well worth the money. I resented buying it because of the price but the simplicity allows me to quickly adjust fps day by day according to temps. It's like owning two guns. Awesome

    "I've had the NPAS bolt system for about almost a year now. I bought it for my KWA LM4. This bolt allows FPS adjustment on a GBBR. ( Helpful in hot region where GBBR shoots high fps due to expanded gas.)
    Pros:
    Drop in installation
    Easy maintenance
    Allows adjustments to fps restrictions


    Cons:
    Bolt requires a special tool to adjust the fps (do not lose it)
    There were no instructions that came with the product (had to do research)
    *I've learned that CCW will decrease FPS and CW will increase

    Overall: I am very satisfied with this product. Well wort the money. Never had problems with it. It does its job.
