If it's carbine length and you want a rail to but up to the Adams piston block, you would need a 7" carbine rail.

A regular 9" rail would be too long and won't be able to go over the gas block.

You could do what I'm doing. I just ordered a DD 9.5 fsp lite rail for my 10.5" carbine length build. The cut out fits perfectly around my Adams piston block.
When it comes in I'll mock instal and post it if I have some time.

I originally tried a DD 12.0 fsp lite rail and that was a little harder to get over the block. But I was able to do it. Looked really nice.
Only problem was the barrel (10.5" ) is way too short and I couldn't get the flash hider on.  I would think a 14.5 pinned barrel would be perfect.

I think Samson has rails that would work too.

Hope that helps.
