What perks apply to the Syringer Rifle in Fallout 4?

I've been thinking of creating a stealth/ Syringer Rifle character build for Fallout 4. The general idea is a character who relies on short range stealth melee and long range Syringer Rifle attacks to get by.

The Syringer Rifle is different from every other Fallout 4 weapon (I know of) in that you have to craft your own ammo - and most of the Syringer Ammo is non-lethal.

This makes me wonder about what Fallout 4 Perks apply to the Syringer Rifle. For example does Riflesman or Ninja increase the damage for Bleed-out or Radscorpion venom syringes?

And does Luck have any effect on the syringes with "Chance" effect? If I select a Critical in VATS will the "Chance" effect always be applied?

Solution 1:

According to the Syringer page on Nukapedia,

The Syringer does not benefit from Quick Hands, Rifleman, Mister Sandman, Bloody Mess, or Ninja, but Sniper 1 and 3 both work.

It's not automatic or a pistol, so Gunslinger and Commando wouldn't work either.

Sniper 1 is

It's all about focus. You have improved control and can hold your breath longer when aiming with scopes.

and Sniper 3 is

Non-automatic, scoped rifles gain +25% accuracy to head shot in V.A.T.S.

I can't find any information on critical hits with the Syringer at all. Not sure if it has any effect. Needs testing.

If luck improves your % chance for the rifle's random effects, I see no evidence to that effect.
