QUOTE:In your original post you said you were looking at a Larue 13.2. This means that you would have to be covering up the FSB/gasblock. I took this to mean that you wanted the FSB/gasblock covered regardless of which brand you bought.
Maybe if you start over with what you want and what you're installing it on we can be more helpful.
Incidentally, you may find some of the information in this thread to be helpful.
IN BURRITO:
The barrel is a Wilson 20" NM stock on the RRA A4.
Yes. I thought if I chose the 13.2" Larue, then the barrel marks or blemishes caused by the removal of the FSB would be concealed under it. However, I wasn't sure what I would need to do with the shorter length DanielD handguard. After checking out that thread that you referred me to, and the Daniel Defense web sight too, it is a lot clearer to me how the DD will work. If I want to do away with the FSB, then I think the Larue is the better way to go.
Thank you for the input.
