The QCQ171 is one of the weapons introduced to Delta Force in Season Starfall and is a solid close-quarter-combat submachine gun. While not as fast-firing as other SMGs, QCQ171 has a higher effective range that you can take advantage of with the right build.
Here are the best attachments and calibration settings for QCQ171 in Delta Force Warfare.

Best QCQ171 build in Delta Force Warfare

While QCQ171 may not be the best SMG in the game, there are ways to build and have fun with it. The high recoil makes it quite difficult to use beyond 30 meters, so this build focuses on mowing down enemies close to point-blank ranges. If you want to fight more at range, there are always weapons like SMG-45 and CAR-15.
Here are the best QCQ171 attachments in Delta Force:
Slot | Attachment |
---|---|
Optic | Panoramic Red Dot Sight (personal preference) |
Bolt | QCQ 171 Newtype Stable Bolt |
Upper Patch | Hornet Handguard Panel |
Right Patch | Hornet Handguard Panel |
Left Patch | Hornet Handguard Panel |
Barrel | QCQ 171 Newtype Red Tassel Tactical Long Barrel |
Right Rail | DBAL-X2 Purple Laser-Light Combo (or any other laser) |
Muzzle | Bastion Horizontal Compensator |
Foregrip | X25U Angled Combat Grip |
Mag | Newtype 45-Round Extended Mag |
Mag Mount | Hornet SMG Mag Assist |
Rear Grip | Newtype Vanguard Light Grip |
Stock | 416 Light Stock |
The QCQ171’s bolt is a unique attachment. There are two options to increase or decrease the weapon’s fire rate. We went with the QCQ 171 Newtype Stable Bolt because it has significantly fewer drawbacks than the alternative.
The QCQ 171 Newtype Red Tassel Tactical Long Barrel increases Range and Control. On the barrel, three Hornet Handguards grant 12 Accuracy to make it more reliable when you suddenly have to fire from the hip.
You also want a laser on the QCQ171. On most weapons, the laser is optional as it compromises your location. However, QCQ171’s base ADS speed is slow even with all the right attachments and calibrations, and since it’s only effective at closer ranges due to the high recoil, you want to be able to scope in as fast as possible.
The rest of the attachments are very straightforward. The Bastion Horizontal Compensator reduces horizontal recoil, the X25U Angled Combat Grip reduces horizontal and vertical recoil, and an extended mag is always helpful in a heated battle. Newtype Vanguard Light Grip and 416 Light Stock increase Control and Handling at the cost of Stability, which isn’t that noticeable at ranges this weapon is meant for.

Best QCQ171 calibration settings in Delta Force Warfare

Through calibration, you can get more Control and Firing Stability at the cost of other Stability-related stats. It’s also best to balance out the calibration that affects ADS Speed because you don’t want it to get slower despite using a laser.
Here are the best QCQ171 calibration settings in Delta Force:
Slot | Setting |
---|---|
Barrel | Weight Limit: +50g |
Foregrip | Placement: +2 Slot |
Rear Grip | Weight Limit: +50g Thickness: -20mm |
Stock | Weight Limit: +50g |
Optic | N/A |
These settings grant 16 percent Extra Control and slightly reduce ADS Movement Speed. If you don’t want to lose ADS Movement Speed, adjust the Weight Limit on the barrel. This reduces Firing Stability, which is a personal preference in this case.
