The MXR-17 has quickly become one of the standout rifles in the Black Ops 7 beta. Its balance of range, recoil control, and adaptability makes it a top-tier choice for players who want consistency across different maps and situations. To maximize its potential, you’ll want a build that enhances its recoil handling while keeping you mobile enough to win mid-range and close-quarters fights. Below is the best MXR-17 class setup for dominating in the beta.

Recommended Attachments

Optic: Mini Reflex 01

• +Precision Sight Picture
  A clean sight picture is crucial in BO7, especially in a beta where visibility can make or break a fight. The Mini Reflex 01 keeps your aim precise without slowing you down, giving you a crisp reticle that’s perfect for both long-range beams and quick mid-range engagements.

Muzzle: Muzzle Brake

• +First Shot Recoil Control

• +Kick Reset Speed

• +Vertical Recoil Control
  This is where the MXR-17 really becomes laser-like. The muzzle brake helps eliminate that initial kick and keeps your follow-up shots consistent. Faster kick reset speed means less time fighting your gun and more time landing shots on target.

Barrel: Long Barrel

• +Damage Range
  Increasing the effective damage range extends how far you can land lethal shots before needing extra bullets to secure a kill. This helps the MXR-17 perform at its best across larger maps, turning it into a powerhouse for ranged gunfights.

Underbarrel: Mobile Recoil Foregrip

• +Horizontal Recoil Control

• +Sprinting Movement Speed
  This foregrip gives you the best of both worlds — recoil control and speed. While stabilizing your horizontal recoil, it also improves sprinting movement, which is key for staying aggressive and repositioning during fights.

Rear Grip: Stabilization Grip

• +Horizontal Recoil Control

• +Recoil Stabilization
  Adding even more stability, the stabilization grip makes your MXR-17 feel like it’s on rails. The combination of both grips drastically reduces sway and kick, giving you supreme accuracy even during extended sprays.

Field Upgrade & Equipment

Field Upgrade: Active Camo
Perfect for sneaky flanks and objective plays. Active Camo lets you reposition undetected or escape sticky situations, which pairs well with the aggressive yet tactical nature of the MXR-17 build.

Tactical: Stim Shot
The stim shot is a must-have in the fast-paced environment of the beta. Quick healing keeps you in the fight longer, especially when trading shots at mid-range.

Lethal: Semtex
A classic, reliable choice. Stick enemies on objectives or clear out tight rooms to control the pace of engagements.

Best Perks

Perk 1: Lightweight
Increases movement speed, keeping you fast on rotations and harder to hit. Perfect for staying mobile with the MXR-17.

Perk 2: Fast Hands
Weapon swap and reload speeds are noticeably quicker, which is invaluable in chaotic beta matches. You’ll never feel stuck mid-reload when enemies push.

Perk 3: Dexterity
Better weapon handling and faster climb/mantle actions give you smoother transitions during fights, letting you outplay slower opponents.

Why This MXR-17 Build Works

The MXR-17’s main strengths lie in its accuracy and consistency, and this class pushes both to their limits. With recoil control stacked across multiple attachments, you’ll be able to beam enemies at range while still maintaining the agility needed for close-quarters gunfights. Pair that with survivability tools like Stim Shot and Active Camo, and you’ve got a loadout that can flex into nearly any playstyle.

Whether you’re locking down lanes on larger maps or staying aggressive in tighter spaces, this class ensures the MXR-17 feels smooth, responsive, and deadly. Expect this setup to remain one of the most reliable during the beta — and possibly even into the full launch.
