Custom Viewmodel Anchor System

[TFA]

Hey,
I'm trying to write a system that allows the user to make their own viewmodel attachments with just lua. For some reason, though, it seems to be getting a completely incorrect position for the bone. Any ideas?

SWEP.VMAnchors = {
	[1] = {
		bone = "Base", pos = Vector(0,0,0), angle = Angle(0, 0, 0)
	}
}

local posvec = Vector()
local angang = Angle()

function SWEP:GetAnchor(id)
	
	if !self:OwnerIsValid() then return end
	
	local ifp = self:IsFirstPerson()
	
	local targent = ifp  and self.Owner:GetViewModel() or self
	
	local tbl
	
	if ifp then
		tbl = self.VMAnchors[id] or self.VMAnchors[tonumber(id)]
	end
	
	if tbl then
		local bone
		if type(tbl.bone) == "string" then bone = targent:LookupBone(tbl.bone) end
		if type(tbl.bone) == "number" then bone = tbl.bone end
		if !bone or bone<=0 then bone = 1 end
		local pos, ang = posvec,angang
		local m = targent:GetBoneMatrix(bone)
		if (m) then
			pos, ang = m:GetTranslation(), m:GetAngles()
		end
		
		if (ifp and self.ViewModelFlip) then
			ang.r = -ang.r
		end
		
		local newpos,newang = LocalToWorld(tbl.pos,tbl.angle,pos,ang)
		debugoverlay.Cross(newpos,5,0.1,color_white,true)
		return newpos, newang
	else
		if type(id) == "number" then
			local angpos = targent:GetAttachment(id)
			return angpos.Pos,angpos.Ang
		else
			local ind = targent:LookupAttachment(id)
			if !ind or ind<=0 then ind=tonumber(id) end
			if !ind or ind<=0 then ind=1 end
			local angpos = targent:GetAttachment(ind)
			return angpos.Pos,angpos.Ang
		end
	end
end

Keep in mind that "Base" is the root bone of the gun and the normal .qc muzzle attachment works fine.
