I've got a real T-1, don't own any real guns personally. 2nd hand, paid waaay under retail, still not cheap though. Makes no difference in airsoft other than the lenses are a bit clearer than ACM clones and the internal soldering doesn't fail under TM recoil. I still objectively suck at playing the game, neither the Aimpoint nor anything else gucci help me in that regard at a sunday skirmish. But I got my first springer 15 years ago now, I've tried absolutely everything else, I've worked, saved up etc and this is what I have now. I'm not going to delve in to the details of my financial status but I'm fortunate to say I'm not struggling.
Personally I recommend Vortex, Primary Arms and Holosun for red dots, on anything with recoil anyway. Just because I've had too many of the real cheap clones fail after firing a mag or two through a TM EBB or GBBRs. They're the low end of RS optics, definitely still pricey for airsoft, but you put some protective lenses on there and you've got a nice T-1 style setup for life. Just the conclusion I've come to after a lot of trial and error but each to their own.
