I like the way it looks - TRYBE Defense AR-15 Lightweight M-LOK Handguard w/ Full Rail

Easy to install, seems well made and looks really good. Haven't fire the weapon since installing the Handguard so can't speak to how well the retaining system works. From an engineering standpoint I don't anticipate any issues as it mounts very solid and tight. What I like is that it is very light and doesn't add much weight at all. Plus, the price point that OP was blasting these things out at makes for a no brainer. I would recommend these Handguard to anyone looking for such an item. Why pay much more if you don't need to.
