Best RM277 Build for Delta Force
RM277 is the 6.8x51mm assault rifle added on June 30, 2026 — the same caliber as the M7 and M250. It's one of the most stable mid-to-long range rifles, with high muzzle velocity and reach of up to 90 m when fully modded, but a little soft up close. In S11 Operations tier lists it dropped from S to A because low limb damage makes its TTK inconsistent; in Warfare it stays S. PLY 6.8 rounds (added June 30) give a control buff during sustained fire.

Frequently Asked Questions
Everything you need to know about mastering this weapon
Warfare: activate it in the Armory, then play 5 Attack/Defend or King of the Hill matches and 120 minutes of Warfare. Operations: it was in the S10 Elite Gear Ticket – Balanced; in Season 11 it moved to the limited Desmoulins Spec Ops Gear Ticket (Balanced).
It's a reliable mid-to-long range anchor. S11 Operations tier lists dropped it from S to A because low limb damage makes TTK inconsistent, but it remains S in Warfare, where guides use it as a long-range, anti-armor rifle.
The S10 6.8x51 PLY-I / PLY-II / PLY-III rounds (penetration 3/4/5) give a control buff during sustained fire. PLY-III is the pick for the full build.
Yes. A community budget setup stays under about 250k: Severance Suppressor (no range or velocity penalty), Dedicated Recoil Pad, the standard 30-round mag and purple 6.8 ammo. New-season parts like the Severance were 400k+ in launch week and fell to 150–200k by mid-July, so prices should be lower now.
No stat changes. A July 8, 2026 fix made the RM277 bipod's attribute bonuses apply correctly.
