    Default Link to instructions?

    Hey all. I'm new to the forum. Hoping to start my conversion for my USC soon but I can't find instructions anywhere and the links on page 1 don't work. Where can I find instructions and photos for the conversion? Thanks.

    I recently completed an 18 month process of a TBostic conversion using all original HK parts, with a lot of extras. It took that long due to funding, parts availability and the ATF. I have a little over $5k in the project, but I am very pleased. Some brief notes;

    * Ed at HDPS is a jerk. I wouldn't send a cap gun to him. Other opinions vary. Consider yourself warned.
    * TBostic is an artist. Well worth the money, and everything is true and correct.
    * PLAN this project out. Regardless, it will be lengthy, from parts availability to ATF delays. Maybe not 18 months, but lengthy.

    Only the following vendors were used for this project;

    HKPro member AviatorDave- purchased the USC
    Adam at All parts (including HDPS US compliancy parts listed below)
    HKPro member TBostic- converson process. Fast, professional and responsive. I can't say enough.
    Tornado Technologies- Fast turn-around time, beautiful work.
    Gray Laser Engraving- Perfect engraving to my exacting specs, fast turn around time. Simply perfect.
