The TRG-21 is a bullpup assault rifle used by the FIA. It features an ergonomical design that supports accurate fire in harsh conditions. TRG-21 is lightweight, ambidextrous, easily serviceable and compatible with a large number of accessories. TRG-21 EGLM is mounted with an enhanced grenade launching module. A carbine variant is labeled TRG-20. Compared to TRG-21, it features a short barrel better suited for close quarters combat situations.
The TRG-21 is a gas operated, selective-fire bullpup assault rifle chambered to fire the 5.56×45 mm NATO round.
It loads from 30-round STANAG magazines, and can attain a fire rate of up to 750 rounds per minute with a muzzle velocity of 920 m/s. The top and side rails support being mounted with optical sights and side rail accessories, while the muzzle can be fitted with sound suppressors.
Along with its sub-variants, the TRG-21 is a fairly decent assault rifle that provides both a high rate of fire and low recoil in a compact package.
Compared to the AAF'sMk20 bullpup, it boasts a slightly greater effective firing range and improved accuracy at short/medium ranges. It is also fairly light to carry and is suitable for use in close quarters thanks to its bullpup configuration.
However, some of the disadvantages that come with the TRG-21 stems from its use of 5.56 mm ammunition. Although this makes its magazines slightly lighter to carry, the TRG-21 has considerably lacklustre performance when it comes to both range and penetrating body armour.
Whilst these downsides do not necessarily render the TRG-21 an inherently poor weapon by any measure of standard, it lacks unique attributes (aside from its accuracy) that would make it stand out compared to other assault rifles in its class.
The TRG-21 EGLM is a modified version of the baseline TRG-21 rifle that has an underbarrel grenade launcher attached to it.
As with its parent weapon, it is also chambered to fire the same 5.56×45 mm NATO round, while the grenade launcher can launch 40 mm grenades with either smoke, flare or high-explosive (HE) warheads.
It loads from the same 30-round STANAG magazines and is completely identical performance-wise aside from having slightly increased inertia. The EGLM uses a red dot quadrant sight that can be zeroed up to a maximum distance of 400 metres.
The TRG-21's ironsights can be zeroed starting from a minimum of 100 metres up to a maximum of 600 metres (100, 200, 300, 400, 500, 600). By default, it is set to a zeroing of 200 metres. Both the front and rear sight are illuminated; the front sight post features an illuminated dot while the rear sight has strips on all four sides of the ring. They emit a pale green glow in daytime but appear brighter under low-light conditions.
If an optical sight with a zeroing limit greater than 600 metres is attached onto the top rail (e.g. Nightstalker), the TRG-21 will allow for an absolute maximum zeroing of 800 metres.

The EGLM grenade launcher can be manually zeroed between the ranges of 50 metres up to 400 metres (50, 75, 100, 150, 200, 250, 300, 350, 400).
It uses a red dot reflex sight. By default, the sight uses a zeroing of 75 metres.

All variants of the TRG-21 support being fed with 30-round STANAG magazines, interchangeable with any other weapon chambered for the 5.56 mm NATO round. They are all available in either a Black or Sand finish, and have identical weights of 8 "mass" apiece:
5.56 mm 30rnd Reload Tracer (Yellow) Mag[]
Basic 30-round 5.56 mm STANAG magazine. The last four rounds of the magazine always consist of yellow tracers.
5.56 mm 30rnd Reload Tracer (Red) Mag[]
Identical to the baseline STANAG, but the last four rounds consist of red tracers instead.
5.56 mm 30rnd Reload Tracer (Green) Mag[]
Identical to the baseline STANAG, but the last four rounds consist of green tracers instead.
5.56 mm 30rnd Tracer (Yellow) Mag[]
Contains 30 rounds worth of visible yellow tracer ammunition. Identical in all other aspects to regular STANAG magazines.
5.56 mm 30rnd Tracer (Red) Mag[]
Consists purely of visible red tracers. Identical to the other full tracer STANAG magazines.
5.56 mm 30rnd Tracer (Green) Mag[]
Consists purely of visible green tracers. Identical to the other full tracer STANAG magazines.
Trivia[]
Along with its sub-variants, the TRG-21 is directly based on the "Tavor" family of bullpup assault rifles designed by Israel Weapon Industries (IWI).
Though they share the same name, the in-game TRG-21 should not be confused with the real-world "TRG-21" sniper rifle designed by Finland-based arms manufacturer SAKO Ltd.
The EGLM on the other hand, is based on the "MK13 Enhanced Grenade Launcher Module", a 40 mm grenade launcher designed by FN Herstal of Belgium that can be used in both standalone and underbarrel configurations.
Prior to Game Update 1.22, dispersion values on the TRG-21 and TRG-20 were reversed. Before the patch's corrections, the TRG-21 (rifle) was less accurate than the TRG-20 (carbine).[1]
The patch also substantially increased the weight of the TRG-21. Beginning with the Alpha and all the way until the patch, both the TRG-21 and its EGLM sub-variant weighed 50 "mass" units as opposed to its current weight of 70 "mass".[1]

Promotional pre-Alpha screenshot with black TRG-21s.
Screenshots released during the pre-Alpha phase of ArmA 3's development indicated that the TRG-21 was originally meant to be a CSAT weapon. By the time of the Alpha and Beta's release however, it was eventually replaced by the Katiba.[2]
It was also available in a Black finish as opposed to the Olive paint used in the final version of the game. Unfortunately, this texture can no longer be found in the game files.
Alpha ironsights.
During the Alpha, the TRG-21's ironsights were modelled differently when compared to its final release version.
The rear sight appeared in the shape of a rhombus as opposed to a ring and had only two illuminated triangles rather than four lines. On the other hand, the front sight was also modelled with a diamond head housing rather than a V-shape, though the central post retained the illuminated ball.
Following feedback from the community, the ironsights were completely remodelled after the release of Game Update 0.52.[3]
