I need a .625 block with piston set up. Anybody know when this will be available? Or if anything already exists?

I've heard the new lightweight kits are almost out? Will they still require the rail to end in front of it or are they like a low pro under rail?

to my knowledge, and based on a prototype review i read, they did not design the lightweight/low-pro blocks to fit under any rails.
