    Very well made and excellent fit, but expensive compared to some alternative systems. The proprietary screw mounting system is excellent for keeping weight at a minimum but allowing you to put rails only where you need them, with several sizes available

    I put this on a PTR 91 to replace a German green thin fore end. The fit was perfectly tight including the pins. Weight was reduced and I can now use a bipod with the attached rail section.

    Does exactly as advertised in a Swiss precision manner. If you have surplus parts on your rifle this will improve your grip, decrease weight and add mounting options to your rifle.

    Vents heat well. Sturdy construction. Unique mounting solution for 1913 rails; the one provided is all I need for mounting the accessory I plan on using.Great feel on the forend.
