Marksman Rifle Mk II

The Marksman Rifle Mk II costs $149,000 to convert (about $340,000 maxed) - a superb semi-auto headshot machine for PvE, but skip it if you already run the Heavy Sniper Mk II.

Key facts

Cost	$149,000 (Mk II conversion at a Weapon Workshop)
Mk II conversion cost	$149,000 (base Marksman Rifle is $15,750)
Total cost to max	About $340,000 (base + conversion + AP rounds, heavy barrel, extended clip)
Worth it verdict	Yes for PvE headshot grinders; a luxury if you already run the Heavy Sniper Mk II
Best ammo type	Armor piercing rounds ($73,560 mag, research required) for armored enemies
How to unlock	Own a Marksman Rifle + any Weapon Workshop; research only gates special ammo
Damage	75 per shot, up from 65 on the standard Marksman Rifle

The Marksman Rifle Mk II is the Weapon Workshop upgrade of the Marksman Rifle, lifting damage per shot from 65 to 75 at the same fire rate. It sits in a unique slot: a scoped semi-automatic rifle that fires much faster than any sniper while still one-tapping heads, making it the best NPC headshot tool in GTA Online for players with good aim.

Costs, as of July 2026: the base Marksman Rifle is $15,750 and the conversion is $149,000 - the second most expensive Mk II conversion - for $164,750 total on the gun. A full build adds armor piercing rounds ($73,560, research required), the heavy barrel ($73,500), and the 16-round extended clip ($26,850), landing around $340,000.

Is it worth it? For dedicated PvE grinders, yes - rapid one-shot headshots clear contact missions and heist setups faster than anything short of explosive rounds, and unlike the Heavy Sniper it can fight at medium range without feeling sluggish. If you already own the Heavy Sniper Mk II with explosive rounds, though, this becomes a luxury; the sniper covers the long-range slot with more raw power.

The loadout to run is armor piercing rounds, heavy barrel, extended clip, and a grip. AP rounds let it punch through armored heist enemies that normally shrug off body shots, and the heavy barrel keeps its damage intact at distance.

For money making, it is a genuine time-saver in headshot-heavy grinds: Cayo Perico scoping and compound work, Casino Heist setups, and agency security contracts all reward precise semi-auto fire. Buy it after the big three, before the style picks.

Tips

Treat it as a fast-firing headshot tool, not a sniper - it wins at medium range where snipers feel slow.
Armor piercing rounds are the key research; armored NPCs are the only targets that survive a headshot.
The extended clip takes it to 16 rounds, which covers an entire wave of enemies without reloading.
The heavy barrel is expensive at $73,500 but keeps one-tap breakpoints intact at long range.
AP and other special mags shrink capacity to 5 rounds - swap to standard ammo for unarmored crowds.
If your aim is inconsistent, the Special Carbine Mk II gives more forgiving results per dollar.
