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.
Available in anodized black, desert tan, and OD green.
TGF
is designed for use with TDP spec forged lower receivers, and fills the
gap forward of the pistol grip, between the trigger guard "ears" (note
that TGF will not swing down like TDP spec trigger guards). All the
sharp edges and corners have been removed.
Lower
receivers made from Cerro Forge "keyhole" forgings generally have taller
trigger guard ears, as do Colt, LMT, and BCM lower receivers.
Please note ZEV
produced lower receivers appear to have shorter trigger guard ears, and
these shortened ears expose a bit of the bottom of the TGF, as shown
below.
This has no bearing on functionality. The latest Mega lowers (with the
old Mega atomic whirl) has been reported to have longer ears that do
cover the TGF.
Left: ZEV made lower receiver. Right: Colt receiver. On these ZEV produced receivers, TGF
lines up with the grip's corner, where the trigger guard is supposed to be.
On receivers that are adhering more closely to TDP specs and tolerances, TGF is near flush with the trigger guard ears.

Though
TGF was designed to be compatible with LMT MARS-L lower's longer
trigger guard ears, the length of these ears can vary. Do note in rare
cases, the areas forward of the trigger guard ears may still need to be
fitted for some MARS-L lowers.
TGF also features an angled front end to facilitate rocking the magazine
into the magazine well. In so doing, the design opens up the magazine
well slightly for those that use the rock into mag well technique. For
those that don't, the angle takes nothing away from the way they're used
to inserting magazines, "beer can" straight into the magazine well.
TGF's
design will not allow the trigger finger to be pinched if the user's
trigger finger happens to be on the bottom of the trigger guard. The
design of maximizing the space forward of the trigger, and keeping the
portion behind the trigger small (as this space is inaccessible to the
user) accomplishes more purposes than one.
TGF is proudly designed and made in the USA. A trigger guard roll pin and set screw (for the front) are included. A 1/16 Allen wrench is required (not included).
NOTE;
TDP
width for the
trigger guard is 0.430 +/- 0.003. TGF follows TDP specs and tolerances.
The gap
between the rear trigger guard ears is 0.438 + 0.008 / -0.000. Given
the rather loose tolerances of the space between the trigger guard's
rear ears, TGF (or any trigger guard, for that matter) could be just
right, or slightly loose. This is normal, the TDP spec width of the
trigger guard and that of the lower inside the trigger guard ears all
but guarantee an in spec trigger guard will be loose inside the ears.
TDP
diameter for the front right ear of the trigger guard is 0.125 +0.003.
If the hole is on on the upper side of the tolerance, TGF's set screw
can rattle inside. This too, isn't unique to TGF.
We'd
like to remind folks that AR15s/M16s are tools, and every part has a
tolerance value. It isn't an advantage or useful feature for combat
weapons to be so tight that they lose their tolerance for debris, sand,
and mud. TDP trigger guards swing down, and they wouldn't be able to do
so if any foreign object in its way can stop them from doing so.
We don't
fudge and get creative with TDP specs and tolerances. If we made TGF on the wide side (didn't even think about
it, but we wouldn't do it anyway because it has problems of its own),
we'd risk the
TGF being too tight and not fitting Colt, LMT and BCM lower that are
true to TDP specs. We design and produce duty grade components for
duty/combat weapons, and we adhere to TDP specs and tolerances.
