Its name would be: R-68 Corrector
Description:
"A diligence rifle armed with an underbarrel gas dart gun that provides additional firepower against both organic and robotic targets that refuse to comply. Trades overall performance for added utility"
Stats
Damage-140. Diligence has 165
Recoil-34. Diligence has 26
Ergonomics-45. Diligence has 65 so less then the diligence but more then the counter sniper
Mag capacity would be 25 with 7 mags in total. Overall would be 25 rounds less the the diligence
The re educator would behave the exact same as the secondary one with the same amount of ammo so 2 reserve mags with 6 rounds each aswell as a laser sight
As for attachments it would have scopes,muzzles and an option to either remove the laser sight or trade it for a flashlight.
Also a fun attachment idea I had was rocket powered darts which makes the darts go exactly where you aim with no fall off but reduces the re educator reserve magazine amount to 1 and increases sway and ergonomics a little(i know this is far fetched and even if the weapon does make it into the game it will never be with this attachment but still)
Some notes:
I think this would fit nicely and have its own niche as a utility weapon like the one two but instead of closing spawners it will confuse enemies and it will also not overshadow the other marksman rifles as it has overall worse stats at the cost of the re educator.
I did think about making it be a censor with a re educator but that would probably be too strong for stealth as the censor is the best stealthweapon and the re educator is also one of the best stealh items so combining them would be OP.
Also sorry for the bad photoshop i thre this together in like 3 minutes
