Bought a 6.8 Stag Hunter with the Hogue free float handguard; you would think this item would fit perfectly, it does not. The clamp/screw/lock whatever" mechanism does not fit flush even after extensive attempts to adjust. I would not expect this item to stand up to any repetitive shooting, much less attach expensive lights to the "cuff" - just tap your hand guard, or spend another $50 and get the handguard you want. This thing is a joke - could not get it back in the package and return it soon enough. Optics Planet took it back with no hassle, no restock fee and was very gracious. This item really is pathetic and an insult to anyone wanting to build a real fighting/hunting AR.
Cons: fits poorly, does not clamp firmly, would not support common attachments
