Wanted: TandemKross “Advantage” Charging Handle and Picatinny Rail for Ruger 10/22

I'd like to purchase the TandemKross Advantage charging handle set for my 10/22 build. Local sales preferred, but if you're across the country, I will pay shipping for it.

If you are local and have this, I'd be willing to trade you my Mosin rifle if you provide an additional $500 on top of the charging handle set, so everything evens out. PAL to be verified upon meetup, if we are conducting the trade. I am available weekends, and usually commute to the Langley area at least twice per month.
