This is the most produced weapon OMNI has, the Bergman FEB 60 and FEB 60A1. It uses the Kel-Tec forward ejection system and uses standard 5.7mm cased ammunition. This is OMNI's most basic assault rifle, intended for use with conscripted soldiers, known as the Vanguard forces. As such it's very simple to maintain and operate- instruction panels cover the weapon, and any switch which usually needs to be pressed or pulled during operation is colored bright red. The weapon has a built in reflex sight which can be removed.

The B-55 was OMNI's initial service rifle from the very beginning of the colonies' incarnation. It was phased out after WWIII and replaced with weapons better suited to paramilitary uses. Once war resurfaced, OMNI brought its old B-55s back out of storage. New production lines of updated weapons were immediately started up, now producing the B-FEB 60 and B-Feb 60A1.

The trigger guard serves as the safety switch, and folds down to free the seer and allow the weapon to fire. After that, the trigger is a double action affair which ensures further safety. The fire rate control switch is just above the grip, easily accessible by the thumb of the firing hand, and the weapon can fire in either semi-auto or 3-round burst.

To increase ease of reloading, the magazine well has a rail which extends out and joins the grip, allowing more instinctive reloading by sliding the magazine in just below the firing hand. Like the Kel-Tec RFB, the weapon ejects spent cases forward above the barrel.

All these factors culminate in a weapon which is easy to use and effectively idiot-proof, and can be marginally effective with little or no training.
