Combat rifle (Fallout 4)

The combat rifle is a weapon $$

Background
A pre-War firearm that can be commonly found in the Commonwealth. Various factions, such as Gunners and raiders, frequently carry them.

Gameplay
The combat rifle is capable of filling various roles depending on its configuration, such as a close-quarters automatic or a precision sniper. It is also chambered for .45 rounds, one of the most abundant forms of ammunition in the game. With higher ranks of Gun Nut, caliber conversions to the weaker .38 rounds and more powerful .308 Rounds become available.

Variants

 * Overseer's Guardian - A unique variant with the Two shot legendary effect, sold by Alexis Combes in Vault 81.
 * December's Child - A unique variant found in the Vim! Pop factory.

Locations

 * Can be purchased at the Diamond City market. Arturo may sell two or three of these rifles. Higher levels would see him selling one already modified with a .308 receiver.
 * One can be found next to a dead soldier next to a beached tank directly west of Libertalia.
 * At any level, a long barrel full stock is in the raider cottage east of Pickman Gallery.
 * Guaranteed to spawn at the ambushed caravan outside of Covenant, on the road to the Medford Memorial Hospital.
 * One will spawn at any level on top of the roof of the Greater Mass blood clinic, next to the body of a dead survivor.
 * On the east side of Greater Mass blood clinic in the back of a burned out vehicle. There is a chance one will spawn next to a skeletal soldier.
 * Combat rifles can be found on almost all the mercenaries at Parsons State Insane Asylum.
 * Around level 15, Gunners will start equipping these with large magazines and long barrels.
 * Can also be commonly found in U.S. Army bases.
 * Fairly common among raiders and Minutemen at higher levels.
 * One can be found during the miscellaneous quest Find the Treasures of Jamaica Plain.
 * Daisy frequently sells one.
 * Alexis Combes frequently sells one.
 * Occasionally carried by trappers.
 * Sold at the Nuka-Cade for 21600 Nuka-Cade tickets (items rotate every couple of days).

Bugs

 * The modification menu for scopes and sights on the combat rifle does not show the 'Glow Front Sight Ring' mod unless there is something other than the basic 'Front Sight Ring' mod attached, but will not be craftable even though its components required are shown as 'None,' which is grayed out. This affects both the normal combat rifle and its variant, Overseer's Guardian.
 * The standard magazine for the Combat Rifle can be invisible, however, while reloading the magazine can be seen. This is just a visual glitch and does not actually affect the weapon in any way.
 * Firing and then swimming will cause the weapon to be held like a bat and prevent firing the weapon.
 * To fix it, just unequip and re-equip the rifle.
 * Can also happen while using unique or legendary variants of the rifle.
