Awesome ffhg - Obsidian Arms S-Pattern Handguard, M-LOK

Cons: its heavy and thats about it.
Pros: everything about this is clean. I wasnt sure aboit the s patterns because they are literally useless. Other then allowing heat to escape and also keeping you from plugging every hole with rail guards or cool awesome gear amd attachments. Although i do wish i had more mounting options instead of these s patterns. But with that being said, they look pretty sick. I usually hate things that their sole purpose is looks. But it isnt just looks. It keeps you from blockimg the holes that allow heat to escape. So all in all, a great product.
