Larue 13.2 on an 18" SPR??

Anyone have pics?? I have a Grendel barrel and upper sitting, waiting for me to decide on a rail…

Need some motivation…

Would a 12.0 cover the gas block entirely, or just mostly? How are they measured? 13.2" to the front of the upper rec’r, or 13.2" of rail?

A 12" will completly cover a mid length gas system. Actually, I think anything over 11" will cover it.

There’s one on Larues web site.

Yep, I think that’s what I need.

The gas system is rifle length, I think.
