I thought it was LST arms on a Savage, or maybe it was just the knuckles? I know Linc experimented a little with it, and someone actually did it on a Savage. I got the parts to check it on a Maxx, I'll have a looksee for ya when I get home.
The only way you're getting Lst arms on a Maxx is with custom bulks. You could probably modify the LST lowers to fit, but the uppers are all wrong for the bulk. You can modify them to mount up, but you couldn't run it as there would be hardly anything left of the bulk or arm.
Hey did you hear that Flex-Tech is making new arms if they get enough orders?
Hey Harold I've sent you PMs. You asked to buy my towers now that I am using Knuckleheads. Are you ready? I'll send you my paypal addy and we can do this.
