I'm a vortex fan but the Sig is a better option. Can't find out if it has a red display or not but the Sig does and I would never go back to a black display . I have Sig Kilo 1600 and it is the clearest and brightest i have used. I paid the same for the 1600 that the 1800 is on sale for now and both are cheaper than the Vortex 1300.
