Despite recent advances in weapons technology, the older G2A4 semi-automatic rifle remains a favorite of special forces units due to its high damage and extremely precise fire—a testament to its high level of craftsmanship.
The G2A4 is a semi-automatic battle rifle, chambering the hefty 6.19x97mm LEC cartridge. The IMC eventually phased out the G2A4 and replaced it with the R101-C Assault rifle, though it still remains in service amongst special forces units due to its reliability and precision.
The G2A4 is a semi-automatic high damage battle rifle used by Pilots. Capable of downing Pilots in 3 body shots or 2 head shots at any range, it is an incredibly consistent weapon. Fulfilling a specific niche between the assault rifles and sniper rifles, it has the ability to remain competitive at mid ranges against assault rifles, while still being able to take on sniper rifles at range. Close range combat should be avoided due to the G2A4's slow rate of fire. Trigger discipline is needed with this weapon against distant and/or highly mobile targets, as it has enough recoil to slightly offset your aim.
The G2A4 Rifle is the old school weapon in the mix of weapons. It is one of the few semi-automatic weapons in the game and does high damage but has a low magazine capacity. With its high accuracy, this weapon is great for long-range battles.
Consider using this weapon on open maps with long sight lines such as Nexus or Training Ground. Adopt a sniper-like approach to engagements with Pilots. Tailor your engagements to medium/long range to take advantage of this weapons superior range against R-101 carbine users.
The smaller magazine makes this weapon less effective against minions. You don't want to get ambushed by a Pilot when you're taking out minions since you'll most likely run out of ammo and have to reload. If you’re going to kill Grunts or Spectres, keep your distance and watch out for incoming Pilots.
The Match Trigger will increase its fire rate from 420 RPM to 720 RPM, a 71% increase. This makes the weapon more competitive at close range. However, this comes at the cost of long range effectiveness, as the weapon will have more recoil. Reloads will also become more frequent, as your clip size is decreased from 14 rounds to 12.
The Suppressor will keep you off the mini-map. Allowing for more liberal use of this weapon against minions without the fear of reprisal from Pilots. However, your killing power with this weapon will be severely compromised against Pilots, as it will require one extra bullet to kill at all ranges. Because this weapon has a slower rate of fire and is more reliant on single shot placement compared to the other Assault Rifles, this will make you less effective overall.
The Extended Magazine mod is perhaps the best overall mod for this weapon, as it will increase rounds per magazine from 14 to 18. Allowing for more prolonged use before reloads, and having no negative repercussions on your effectiveness.
The Holographic Combat Optical Gunsight has an open sight picture, making it easier to acquire and track targets, particularly in the vertical. The gunsight is fixed at 1.85X magnification, and includes integrated ammunition readouts.
The Holosight’s optics are fixed at a 2.1X zoom factor. The sight picture is designed to induce a tighter visual perception, making it effective both at range and in close quarters. The Holosight is equipped with an integrated ammunition readout.
The AOG, or Advanced Optical Gunsight, is fixed at 2.4X magnification, and includes an integrated “current magazine capacity” readout with a backup numerical display. The AOG is ideal for combat at extended range.
The magazines are visibly marked, indicating the G2A4 fires a fictional "6.19x97mm LEC" cartridge.
Design-wise, the G2A4 might be inspired by the real-life M14 EBR (Enhanced Battle Rifle).
Like many weapons in the game, the G2A4 Rifles has been signifcantly buffed in the fourth update of Titanfall. Unsilenced, it now can kill a pilot in 3 shots instead of 4. The kick produced by firing has been reduced and its clip size has been upgraded to 12 rounds per mag instead of 8 when the match trigger attachement is used.
