I have an Armalite AR15 Carbine that is a mid-length gas system. Looking to put a Larue gas Block on to get rid of the railed one I have.

They offer 2 sizes..anyone know which one to use?

ยท LT202-1: LaRue Low Profile Gas Block - 0.75" AR15
ยท LT202-2: LaRue Low Profile Gas Block - 0.625" AR15

If this is the rifle you speak of.  It appears to be .750

Yep .75 is the one you are looking for.

I did the same thing with the .75 gb and the 13.2" rail system.  Works great for me, i had to have the gunsmiths at RRA install it for me though.  Those larue rail systems are a pain to install.
