Needing help with swep making, weapon bullet.

[Monoleg]

So im trying to learn lua & shit
Im reading others code
making simple stuff

Im currently trying to modifie a swep called Pretty Light Gun, from : Lord Dude
Im making it a gun,

The bullet/light "ENT" are not going out of the gun, my gun point down and the bullet going up

So my question is this: how do I make my bullet get out of the gun barrel,
I thought of putting a offset, on where the bullet spawn, but then I would have to change it angle ?

Here a video showing what im talking about,
[video=youtube;Kvv2rGrwrnA]http://www.youtube.com/watch?v=Kvv2rGrwrnA[/video]

Here SWEP:PrimaryAttack:

function SWEP:PrimaryAttack()
	if ( !self:CanPrimaryAttack() ) then return end
	if SERVER then
		local tr = self.Owner:GetEyeTrace()
		local ent = ents.Create("flaresmg_flare")
		local RecoilX = math.random(-self.Primary.Recoil*2500,self.Primary.Recoil*2500)
		local RecoilX2 = math.random(-self.Primary.Recoil*2500,self.Primary.Recoil*2500)
		local RecoilY = math.random(-self.Primary.Recoil*5000,self.Primary.Recoil*20000  )
		if (ent:IsValid()) then
			ent:SetPos(self.Owner:GetShootPos())
			ent:SetAngles(self.Owner:EyeAngles())
			ent:Spawn()
			ent.Owner = self.Owner
			ent.Stay = false
			local phys = ent:GetPhysicsObject()
			local shot_length = tr.HitPos:Length()
			if (phys:IsValid()) then
				phys:ApplyForceCenter(self.Owner:GetAimVector():Ge  tNormalized() *  math.pow(shot_length, 5) * Vector(100000+RecoilX, 100000+RecoilX2, 100000-RecoilY))
			end
		end
	end
	self.Weapon:SetNextPrimaryFire( CurTime() + self.Primary.Delay )
	self.Weapon:EmitSound( self.Primary.Sound )
	self:TakePrimaryAmmo( 1 )
	self.Owner:SetVelocity(self.Owner:GetVelocity()+se  lf.Owner:GetAimVector()*-self.Primary.Recoil*15-self.Owner:GetVelocity())
	self.Owner:ViewPunch( Angle( math.Rand(2,0.5) * self.Primary.Recoil, math.Rand(-1,1) *self.Primary.Recoil, 0 ) )
	self:ShootEffects( self )
    return true
end

Im also using a code im my gamemod that put a 3rd person cam on the player eye:

local head = pl:GetAttachment( pl:LookupAttachment("eyes") );
local AliveView = {                                      // Cree la vue 1st person 3rd person cam
         origin = head.Pos+(angles:Forward()*3),            //Si le joueur est en vie
         angles = Ang,
         fov = fov, 
        };
        return AliveView

and with this the bullet are being spawn in the midle of my screen

So after much search I found a way,
My bullet now spawn at my barrel and the angle is ok.

The bullet now spawn on the weapon model position itself and with a offset same for angle
I found out how to do it reading Kogitsune's Portable Radar code, so thanks

I also had to modifie the player view because the gun point down and shoot down, so now the player look down, to do this I had to aply a angle offset but, I did not know how to add one to the view I allready had so now the view angle is stuck on the player model head angle with a offset.

But now my view move/vibrate to mutch/fast, how could I smooth my view?

Here a video of the bullet comming out of the barel and the view:
