Rifles
There are more rifles in Counter-Strike than any other weapon group. They're some of the most expensive - and most powerful - weapons in the game. All rifles can penetrate certain solid objects like crates and doors, and some even have zoom capabilities.
Colt M4A1 Carbine
Retail name: Maverick M4A1 Carbine
Caliber: 5.56mm
Price: $3,100
Clip capacity: 30
Description: Early versions of Counter-Strike's M4A1 were equipped with a scope. This functionality has since been dropped in favor of a more tactical feature: a silencer. Like the H&K USP Tactical, the M4A1 is better off when silenced, which activates when you use its special weapon function. Sure, it loses a little bit of its power, but the benefits gained by being completely silent when firing this weapon greatly outweigh the small costs. The M4A1 has average recoil and a fast rate of fire. It's also fairly accurate at all except extreme distances, making it one of the most well-rounded rifles in the game. Unfortunately for terrorists, this is a counter-terrorist weapon only.
Recommended use: Always equip the silencer. It adds a little more accuracy and makes the gun almost completely silent. The M4A1 is surprisingly accurate over long distances, so don't be afraid to engage an enemy early if you're carrying this rifle. Just make sure to fire in bursts.
Steyr AUG
Retail name: Bullpup
Caliber: 5.56mm
Price: $3,500
Clip capacity: 30
Description: The Steyr AUG is a counter-terrorist-only weapon and is a good alternative to the Colt M4A1. It doesn't have as fast a rate of fire as the Colt, it's not as powerful, and it can't be silenced. Despite these apparent drawbacks, the AUG does have some redeeming qualities in its high accuracy and zoom capabilities.
Recommended use: The AUG functions exactly the same way as the terrorists' Commando. It can be zoomed once, does the same amount of damage, is just as accurate, holds the same amount of ammunition, and features the same rate of fire. So, like the Commando, the AUG should be fired in short bursts and, preferably, while kneeling. And whenever possible, use this weapon's scope for added accuracy and pseudo-sniping capabilities.
AK-47
Retail name: CV-47
Caliber: 7.62mm
Price: $2,500
Clip capacity: 30
Description: The terrorist-only AK-47 packs quite a punch for its relatively small price tag. It suffers from a lack of accuracy and limited ammunition. However, for cash-strapped terrorists, the AK-47 is a great weapon and one that can mow down enemies at drop of a hat.
Recommended use: The one thing to keep in mind when using the AK-47 is that its first two shots are the most accurate, and every subsequent shot will stray further and further from your reticule. So the proper way to use the AK-47 is to fire it in two- or three-shot bursts. Holding the trigger down any longer is almost completely useless. The AK-47 should also be avoided in large maps where accuracy is required to tattoo enemies at great distances. In close-proximity areas, however, the AK-47 is a great alternative to either of the game's shotguns.
Sig SG 552 Commando
Retail name: Krieg 552 Commando
Caliber: 5.56mm
Price: $3,500
Clip capacity: 30
Description: The terrorist-only Commando is the equivalent of the counter-terrorists' Steyr AUG rifle. It can be zoomed in once, and has a decent rate of fire, has good penetrating capability, and packs quite a punch.
Recommended use: The Commando is one of the best all-around weapons and has only one serious drawback: a severe recoil. When the trigger is held down indefinitely, the Commando loses a lot of its accuracy. But when it's fired in bursts, especially when zoomed, its rifle's accuracy becomes deadly. More so than any weapon, the Commando should be fired while crouching. Whenever you can, use the scope's zoom feature. Doing so reduces its rate of fire, but greatly increases its accuracy. The Commando can also be used as a sniper rifle if you're on a budget.
Sig SG 550 SWAT
Retail name: Krieg 550 Commando
Caliber: 5.56mm
Price: $4,200
Clip capacity: 30
Description: The Sig SG 550 SWAT is the counter-terrorist answer to the terrorist's G3. It has two levels of zoom capability, and it can be fired in full-auto, even when the scope is being used.
Recommended use: As a counter-terrorist, you have the option of buying one of three sniper rifles, including this one. While it may be cheaper than the AWM, it doesn't have its appeal - as a sniper rifle, its not as accurate. However, if you plan on using it as an assault weapon, its full-auto capability will undoubtedly prove useful. Like the AWM, it has good penetration capabilities, but also suffers from heavy weight, which ultimately negates its usefulness as an assault rifle.
Steyr Scout
Retail name: Schmidt Scout
Caliber: 7.62mm
Price: $2,750
Clip capacity: 10
Description: The Scout is Counter-Strike's second, and inferior, bolt-action sniper rifle. Functionally, it's equivalent to the AWM, but it lacks the accuracy and power.
Recommended use: While its price tag might be appealing, if you can't afford a better sniper rifle like the AWM or even the G3, you're better off spending your money on an assault rifle. While the Scout is fairly accurate and packs a moderate punch, it fades in comparison to the AWM. And while the AWM can be accurately fired from a standing position, you must crouch when firing with the Scout. It is the lightest of all sniper rifles, however, which means you can run at a nice clip while carrying it.
Arctic Warfare Magnum
Retail name: Magnum Sniper Rifle
Caliber: .338
Price: $4,750
Clip capacity: 10
Description: The Arctic Warfare Magnum, or AWM, is the most powerful weapon in Counter-Strike. It can cut down an armored enemy with a single hit, and it's deadly accurate at all ranges, thanks to its powerful scope that can be magnified twice by pressing your special weapon function key.
Recommended use: Despite its hefty price tag, the AWM should be your sniper rifle of choice. Never fire the AWM without the scope, as it's surprisingly inaccurate that way. When you have an enemy in your scope, don't worry about leading him, since the bullet will effectively hit your target the moment it's fired. And of course, try not to miss because you must chamber a new bullet after every shot, and that alone takes a few seconds. Also, remember that the AWM can penetrate solid objects as well as people, so don't be surprised when you kill two or three enemies with a single shot.
Heckler & Koch G3/SG-1
Retail name: D3/AU-1 Semi-Auto Sniper Rifle
Caliber: 7.62mm
Price: $5,000
Clip capacity: 20
Description: The terrorist-only G3 is a little less accurate and less powerful than the AWM, but it does have some redeeming qualities as a sniper rifle. Its firing mechanism is semi-automatic, meaning you won't have to chamber a round after each shot. When situations get a little hairy, the G3 also serves as a competent assault rifle, although you'll be hindered by its heavy weight.
Recommended use: The G3 comes with a heavy price tag, and it should be avoided if all you plan to do is snipe. Go with the AWM instead. If you do buy a G3, keep in mind that this gun won't zoom out after every shot - like the AWM - so keep your finger on the trigger. Always go for a head shot because, unlike the AWM, a single hit with the G3 won't always kill enemies.
