I need to get a new position using a position, direction and maximum length

This is what I use when I already know 2 positions

p.CFrame = CFrame.new(pos,MuzzlePos)*CFrame.new(0,0,-s/2)

but…

Variables

--Variables

local raycastparams = RaycastParams.new()
		raycastparams.FilterDescendantsInstances = {player.Character, game.Workspace.Bullets, game.Workspace.Discoveries}
		raycastparams.FilterType = Enum.RaycastFilterType.Blacklist
		raycastparams.IgnoreWater = true

local raycastResult = workspace:Raycast(MuzzlePos, dir.unit*maxrange,raycastparams)

--MuzzlePos is the first Vector3 position. It's just the position of the gun's muzzle in the workspace.
--In this case for example, maxrange = 500 Studs
local mousePos = mouse.Hit.Position
local direction = (mousePos - MuzzlePos).Unit * maxrange

--[[
local pos = raycastResult.Position  When the gun is fired at something within 500 studs, I get this. However in this scenario, I don't. But the variable which comes after this is useless since the part is just going to be 500 studs long anyways.
]]
local s = (pos-MuzzlePos).magnitude

I’ve tried other ways but they were all botched attempts/edits and they all failed. I don’t know how to proceed from here with all the known variables either.

Apparently just sleeping, waking up the next morning and doing it again solved it.
Here’s what I came up with.

local pos = direction

That’s it. It works perfectly now. I’m in disbelief.
