At first glance I thought it was Lukes beta rail, but I want to say it's a logic rail
i was told by the guy that i bought it from that it was an alpha rail, not sure if it's luke's or logic's.
looking at some google images i don't think it's logic.
posted on facebook, but i'll post here too: logic alpha. i need a picture from the top if you can get one to confirm (z-lock channel is different). note this rail can only be used with classic bodies while lukes are machined to also accept emag / rt pro bodies.
To me, it looks like one of Cyberaves's rails. No clue on how many he made but they are very similar to the logic rail. the most noticeable difference is "wings" at the back are milled much thinner.
They are ridiculously light and if I remember correctly, could be a bit fragile due to how thin they were milled. Each one was unique so there were ever-so-slight variances between each one.
thanks, guys.
