Damn! I was hoping I could get away with the 7.3 instead of 7.5.
I have a brand new Grenadier Precision Carbine length handguard (really kick butt piece btw), but there are two thumb screws at the front end for the upper rail. I plan on mounting a KFH (already have it) but the KFH won't fit between the thumb screws. I either cut down the thumb screws or trade it off for a DD, Larue, KAC, Troy, Samco rail.
Bummer. That rail is frikken nice. I don't really want to modify the screws if someone else could use it as is.
I have a DD on my rifle, nice but I like the round monolithic look of this type of HG.
I like the Troy except they forgot to finish the rail. Those grooves that run down the length ruin if for me. Diddo on Samco as they look identical.
Well, since you guys seem to like the 7.3 I might give it try. I wanted the same rate of twist as my rifle and they are the only game in town with 1:7.
