I am wondering what the slot spacing on them is? i know the EGW spacin g is standard at 10mm as per picatinny specs is the RT the same it looks like a well made piece of kit i dont usualy like slotted holes to make rails multifit but with a 22 that is not a real issue if it was a 308 then there would be an issue. I think the RT looks a lot nicer and with the cutout it is probably needed on a small action like a 220.
