Not so sure it would make much of a difference with the rail going a bit over the battlecomp. The gas would still vent from the comp. I did a bunch of searching around and didn't find an 8" or 8.x" handguard anywhere.


I'm glad you posted that pic by the way. I've been wanting to know the exact measurement to the A2 sight for a mid-length gas set up because that's how I'm going to build the next rifle. 9.25" is apparently it.

Knight's makes their URX 4 in an 8.5" version, but it's KeyMod: http://www.rogtac.com/kac-urx-4-ibn-rail-assembly-8-5/

Maybe you should measure with the BABC with a crush washer or shims to get a better measurement.

I held the BC off the barrel a little more then a 1/16" i nthe pic to count for it.

It would be a shame to not use that BABC... Just use shims, or a peel washer, to get the desired extension past the end of the rail and proper timing. It wouldn't take too much shimming to get the look you're going for.

That's the route I took. 9" rail over an 8.5" .300 BLK barrel w/ Kaw Valley linear comp

I like it. A linear comp on a short barrel works pretty well, and I like the look.
