Thinking of maybe the sharpshooter slugthrower with detonator rounds... Anyone got a better option

Disruptor Rifle

Under-Barrel Micro-Rocket Rack or Micro-Rocket Armour Mounting.

More information on what you are looking for would be helpful.

Honestly a Slingshot and Grenade would literally be the best Bang for your Buck...8)

So im doing a pathfinder or trailblazer / martial artist (later maybe assassin)

And while mostly fighting unarmed or with a simple melee weapon, he was stranded on a desolate world for a while and scavanged some sort of ranged weapon, mostly used to keep big nasty predators at bay... Now that he's off planet he uses it only in extreme situations a back up or preemptive strike on a big baddie. So it's gotta be something you'd find in an abandoned base not something super duper rare Or expensive.

A blaster rifle or dare i a suggest a heavy blaster rifle.

..pretty much anything with Autofire, unless you're actually looking for a ranged weapon the Blast Quality...in which case;

Arakyd Accelerated Charged Particle Array Gun (Dangerous Covenants p.42)

or

Corondexx VES-700 Pulse Rifle (Fly Casual p. 44)

Both are Rarity 6, Under 1000cr and have the Blast Quality (5 & 6 respectively)

There are also several Slug-Throwers that have Blast on this page; http://swrpg.viluppo.net/equipment/weapons/category/2/

Though I am curious to know where you got "Detonator Rounds" from...never heard of them but sounds like the kind of thing my Gand would appreciate...8)

The VES-700 is great for clearing a room of pesky minions. I recently used one to drop six of eight Imperials in a hangar bay using a single attack.

Also under the Index there are a number of Odd Weapons under "Other" that Have blast; Flame Projector, Cryoban, Acid Projector...all are Heavy Weapons

The sharpshooter sluthrower has detonator rounds, check oggdudes creator its listed.

Detonator rounds are alternative ammo for various Czerka slugthrowers (Model 38, EtU pp 40-41 and Model 57, SS, pp41-42). They replace the Pierce characteristic with lowish Blast ratings and Knockdown.

EDIT: Corrected Model #

T-7 is a boss

T-7 Ion disruptor. So what if it's use is considered a war crime?

Z-6 rotary blaster cannon. Frelling silly when properly modded...

If he scavenged from an abandoned base, have it be a Wookiee base, and he found a bowcaster. I like the thought of a non-wookiee with a bowcaster because he spent years in the wilderness with no other options. Otherwise, price/damage leans to Blaster Rifle, Heavy Blaster Rifle, or Light Repeating Blaster (depending on cost).

Concussion Rifle and Pocket Grenade launchers from Forged in Battle are your definite best bet.

I really like the KS-23 Hammer, it's basically a Shotgun. 1500cr/rarity 5 makes it fit your particular narrative requirements, Damage 8, Blast 6, knockdown. But it's the 4 Hard Points that really are great. Sure it's range is only Short, but it still hits very hard for a slug thrower.

Bowcaster and the hammer sound and love like good choices.
