Here is a rundown on them ...
7" (carbine length) -- $110.00
9" (Mid length) -- $120.00
11" (rifle length) -- $130.00
14" (full length) -- $145.00
These have a full length top rail and no side rails
The 5 slot piccatinny rail sections are $20.00 apiece and you can add them wherever you need them on either side or on the bottom ...
They will fit over a low profile gas block or you can strategically design them (depending on length) to end just before a gas block with piccatinny rails (top and/or bottom)
Here is a pic of one of them (for reference):
