TGF (Trigger Guard, Forward Controls) is available in standard (straight) and winter versions. Both are machined from 7075 aluminum, they do not have spring loaded detent for the front, but use a set screw like Magpul's, and a standard trigger guard roll pin in the rear.
We retained the use of roll pin for TGF's rear, as it's reliable and robust, it also will not loosen. The front set screw (1/16 Allen wrench is required) is flush with the receiver and doesn't protrude.
Both versions feature a canted front edge to make rocking the magazine into the mag well easier. The winter version has as much constant/unchanged space from the trigger bow forward as possible (instead of the space inside tapering and decreasing as the trigger guard nears the receiver's front trigger guard holes). The space to the rear of the trigger bow is inaccessible for the user's finger, so it's kept small and low.
