Selling 1 Master series arm...it's been to Robert Luna, for 1 new spring, and 2 fresh cables in September/2014, and has barely been used since(4 days) It's in great shape, and works wonderfully. I believe it's 40-65lbs...ish capacity. I'm sure Mr.Luna could verify it's condition.
It comes with 3 sizes of post, rain/dust covers...oh yea, and a titanium socket block.
I'd like 6000usd, plus freight charges.
Contact me at firstname.lastname@example.org with any questions, more pics etc.
