Buck's loadout and gadget

An under-barrel shotgun (Skeleton Key) attached to his primary — destroys soft walls/floors and damages defenders at close range.

Ubisoft's Buck page has the current loadout; SiegeGG's Buck stats track pro picks.

Buck's strengths

• Skeleton Key creates breach holes at distance (no need to be at the wall).
• Camrs is a strong DMR for long-range picks.
• Frag secondary for direct kills.
• Works on both soft walls AND soft floors.

Who counters Buck?

Operators that counter Buck:

• Mute (limits floor breach above protected hatches).
• Maestro (Evil Eye below catches vertical Buck).

Playing against Buck

Same as Sledge — reinforce critical floors and place Maestro Evil Eyes below common vertical drop spots. Buck is slightly louder than Sledge (shotgun blast) so audio cues can warn defenders.

Climbing ranked with Buck

Use Buck for vertical play on maps with multiple floor levels (Coastline, Skyscraper). His Skeleton Key shoots from distance — he doesn't need to be flush with the floor to breach. Pair with a hard breacher for combined wall + floor exec. The Camrs DMR is excellent for long-range angle holds.
