The Sidewinder is a.450 caliber adaptive Battle Rifle in Modern Warfare 3, offering both Automatic and Semi-Automatic fire modes for versatile close- to mid-range engagements.

Despite its controversial flinch, this MW3 guide suggests an innovative class setup to turn the disadvantages of the Sidewinder into advantages. Here’s the optimal META build for the untamable Sidewinder.

Modern Warfare 3: How to Avoid Kicked for Inactivity Error

The new Modern Warfare installment is removing active players due to inactivity; here’s how to avoid this error in multiplayer.

The Best Loadout for Sidewinder

Because it’s a pushback-heavy BR, the Sidewinder requires a recoil-deduction setup with the RB Regal Heavy Stock, SL Crater Heavy Barrel, RB Borealis Rear Grip, Bruen Heavy Support Underbarrel, and the Slate Reflector Optic.

  • Optic: Slate Reflector
  • Barrel: SL Crater Heavy
  • Underbarrel: Bruen Heavy Support
  • Rear Grip: RB Borealis
  • Stock: RB Regal Heavy

This build is effective in that it minimizes the initial kickback. However, its downside is the above-average ADS, which hinders close-range combat against SMGs and Pistols.

Sidewinder META Class Setup

Considering the Sidewinder’s long-winded TTK, a movement-boosting class setup is a must. To assemble such a build, players will need to go with the Infantry Vest, Covert Sneakers, and Scavenger Gloves. The best options for the Tactical, Lethal, Gear, and Field Upgrades are Stun Grenades, Frag Grenades, EOD Padding, and Munitions Box.

  • Secondary Weapon: WSP-9
  • Best Vest: Infantry
  • Tactical: Stun Grenade
  • Lethal: Frag Grenade
  • Field Upgrade: Munitions Box
  • Gear: EOD Padding

The Gunner and Demolition Vests are also excellent choices, especially for aggressive playstyles.

An Overview of Sidewinder in MW3

call-of-duty-modern-warfare-3-feature

Resembling the real-life Bushmaster ACR, Sidewinder has been titled one of the worst Battle Rifles in Modern Warfare 3’s Pre-season. Part of the reason is the gun’s firing modes — auto and semi-auto — which have little to no effect on its kick and recoil.

To unlock the Sidewinder, players must up their level to 25 by completing Armory Challenges or extract it from the Zombies map.

However, the grind is not worth it. Before a buff fixes Sidewinder’s inconsistent performance, players can skip this BR, replacing it with the META option, Bas-B.
