The Sidewinder is a .450 caliber adaptive Battle Rifle inModern Warfare 3, offering both Automatic and Semi-Automatic fire modes for versatile close- to mid-range engagements.
Despite its controversial flinch, thisMW3guide suggests an innovative class setup to turn the disadvantages of the Sidewinder into advantages. Here’sthe optimal META build for the untamable Sidewinder.

The Best Loadout for Sidewinder
Because it’s a pushback-heavy BR, the Sidewinder requiresa recoil-deduction setupwith the RB Regal Heavy Stock, SL Crater Heavy Barrel, RB Borealis Rear Grip, Bruen Heavy Support Underbarrel, and the Slate Reflector Optic.
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 Upgradesare Stun Grenades, Frag Grenades, EOD Padding, and Munitions Box.
The Gunner and Demolition Vests are also excellent choices, especially for aggressive playstyles.

Best Sidewinder Attachments
Ideal attachments for the Sidewinder arerecoil- and kick-control add-ons. The weapon has an incredibly high vertical recoil, which must be negated with a stock, underbarrel, and rear grip. The following table highlights the best options for each attachment slot.

An Overview of Sidewinder in MW3
Resembling the real-life Bushmaster ACR, Sidewinder has been titled one of the worst Battle Rifles inModern 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 bycompleting Armory Challengesor 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.
