Matrix Aero 15" FF Keymod Handguard

[ChaseFan9]

Is anyone running one of these?  What's the inside diameter of the tube?  I'm going to e-mail Chris and ask, but I figured it might be quicker to ask y'all, seeing how it's the weekend and all...

 

Here's the link, BTW:

I bought one from Chris with a set of the blem receivers - nice design, unusually small diameter - easy to hang on to.

Inside dimensions are, just under 1-1/4" side to side x just under 1-1/2" diagonally  and 1.700" bottom to inside of pocket for the gas tube.

Thanks, guru, that'll work :) Nice build, BTW, I'm working on the same thing but with one of Criterion's rifle length 16" barrels.  

Anyone know of an adjustable gas block (.750) that'll fit under that?

Where's edit?  I forgot to ask, how wide is the gas tube pocket?  Looks like, as long as it's wide enough, there are several adjustable gas blocks that'll fit under that handguard.

I'm measuring the pocket at .347" wide - it's not very roomy in there, I went with a YHM low profile steel block:

 Great price by the way     http://www.mackspw.com/Item--i-YHM9381A

And I am interested in trying one of these adjustable gas keys if it turns out that I'm over gassed - seems most are!

Interesting that the gas key has been mentioned here but, nobody has tried one yet?
