- Rear Grip: RB Rapidstrike Grip
- Underbarrel: FTAC SP-10 Angled Grip

This particular build for the MCW is catered towards enhancing your stability and handling of the AR. The Slate Reflector is a great sight to go for as it is very clear when aiming at targets. You can go for other optics, but the Slate Reflector works in almost every given situation.
The MCW Ironbark Tactical Stock increases your Tac stance spread, hipfire spread, Aim Down Sight speed, and Sprint to Fire Speed. Therefore, you will be much more potent when taking close-range gunfights in maps like Rust, Skidrow, and Favela.
The RB Rapidstrike Grip further enhances your Sprint to Fire Speed and ADS speed. This will ensure that you can react to gunfights more effectively, especially against players who love to run around with SMGs.
The FTAC SP-10 Angled Grip provides a significant boost to Horizontal Recoil, Aiming Idle Sway, Gun Kick Recoil, and Aim Walking Steadiness. This particular grip will ensure that you are steady when firing your gun which is perfect to take advantage of the MCW’s strengths.
Lastly, the SL Crater Heavy Barrel provides Recoil Control, Aiming Idle Sway, and Gun Kick Control. In this, the key is to further enhance your stability and improve your accuracy in mid to long-range gunfights.

- Vest: Gunner Vest
- Gloves: Scavenger Gloves
- Gear: Tac Mask/EOD Padding
- Field Upgrade: Trophy System
Modern Warfare 3 introduces a new perk system that sees players equip vests and gear for benefits as opposed to selecting perks.
The Scavenger Gloves ensure ammo will never be a problem for you. This will come in handy on big maps where you might be close to a kill streak, but you run out of ammo. Meanwhile, the Gunner Vest will ensure that you deploy with max ammo and it also increases your reload speed.
Both Tac Mask and EOD Padding are solid options for gear, and it depends on whether you’re more concerned about incoming tactical or lethal equipment.
Lastly, a Trophy System will come in handy in game modes such as Hardpoint or Domination, where you are likely to get bombarded with grenades and flashes while playing the objective.
