Automag to Spydermag?

[FallibleFlyer]

Here is my current automag. I have an emag valve with ULT on the way and am debating turning my baby into a spydermag. Anyone have any input on this move? Keep it the way it is? or spydermag it.

Current Setup:
"Field Rental Valve" Modified to accept lvl 10
Freak Barrel kit
Centerfeed No-Rise twistlock body
Dye Single trigger frame w/ aluminum grips

Spydermag frames need RTP rails just to let you know.

I thought you could do it with any rail? Why only RTP?
