Modern Warfare 3 brings exciting new camos to unlock and you’ll need to level up every weapon to get your hands on them all. To help with the grind, here’s the best Sidewinder Battle Rifle loadout for MW3.
There are plenty of different weapon types to try out in Modern Warfare 3‘s multiplayer, and of course, some are better than others.
The Sidewinder Battle Rifle is far from the best gun in Modern Warfare 3 but if you’re looking to unlock all of the mastery camos or fancy a challenge, you’ll need to equip the best loadout before using it in multiplayer.
Here’s the best Sidewinder loadout for MW3 including attachments, Perks, and Equipment.
Best MW3 Sidewinder loadout attachments

You should focus on recoil control when building the Sidewinder.
- Muzzle: Bore-490
- Barrel: Tempus Predator Precision Barrel
- Optic: Mk. 3 Reflector
- Underbarrel: Bruen Heavy Support Grip
- Rear Grip: RB Borealis Grip
The best Sidewinder loadout for MW3 is all about increasing its accuracy at the cost of mobility. It’s not a weapon you’re going to be running around and dominating with, so play to its strengths by concentrating on hitting your shots.
The Tempus Predator Precision Barrel helps with the Sidewinder’s bullet velocity and recoil control, making those far-off targets a bit easier to hit. It still suffers from horizontal recoil so adding the Bore-490 Muzzle and Bruen Heavy Support Grip will stop the weapon from jumping side to side as much.
Finally, the Mk. 3 Reflector makes enemies easier to see, and the RB Borealis Grip further controls the recoil.

Best MW3 Sidewinder loadout Perks & Equipment
- Vest: Overkill Vest
- Gloves: Marksman Gloves
- Boots: Covert Sneakers
- Gear: Ghost T/V Camo
- Lethal: Semtex
- Tactical: Flash Grenade
For the best Perks and Equipment to use with the Sidewinder, we’ve opted for the Overkill Vest for increased weapon swap speed and the ability to reload while sprinting, countering some of the weighty attachments.
The Marksman Gloves reduce sway and flinch, making the weapon slightly more accurate. Then, the Covert Sneakers and Ghost T/V Camo let you move around the map without your footsteps being heard or UAVs revealing your position when moving.
Finally, the Semtex is an easy-to-use and powerful explosive, and the Flash Grenade will blind enemies long enough for you to get a quick kill.
