15" handguard surpasses the gas block on rifle length, by 1.5 inches at least. 12" handguard will cover half the gas block -- which is a nice look.
f:P
I'm planning on a 17” handguard
I did a 17” handguard with a 20” barrel with a brake on the end and it looks perfect.
here's a handy reference for gas block positions depending on gas system.
Gas System Distance from Receiver to Gas Block Shoulder Pistol 4 1⁄4" Carbine 7 5⁄16" Midlength 9 5⁄16" Rifle 12 5⁄8"
note that gas blocks are usually 1" long so add 1 to get the minimum length of handguard to cover the gas block.
for a Rifle length system, 13.5" handguard will just barely cover the gas block (the block will be slightly proud) so I'd use 15" as a minimum.

Thanks TNA, i knew i was a little off topic, but you guys rock.
Thanks to everyone else as well, will show pics when my build is complete....hoping the next few weeks.
So I just received mine today. Here is my initial report:
- The finish is good, doesn't seem flaky at all. Its been done pretty well, so i'm happy with that.
- My Radian ambi charging handle and PWS bolt carry fit in the upper
- The notch for the charging handle latch is present which is also good
However there are some issues with the trigger pack. The selector switch hole is slightly off alignment from the ones on the receiver itself, but its an easy fix. Next thing i need to test, is the bolt catch pin. Hopefully i won't have too many issues there.
Here are some pics:
