Review by Douglas B. on 18 Dec 2024review stating Unfortunately just not great
I really wanted to like this handguard but it is just lacking in some pretty basic features that prevent it from being worth a purchase.

handguard doesn't fit great against the upper receiver and there is a significant amount of play and slop prior to tightening. Once tightened to the manufacturers specifications it will still move if enough force is applied. For most users that don't have lasers this probably isn't an issue but still doesn't exude an impression of a quality product compared to all of the other options in today's market. Lastly there are just a few other smaller things like painted rail markings instead of engraved, and markings every 4 slots instead of every 2 like most other quad rails. It just has a "cheap" feel and appearance. I would have returned it but didn't want to have to pay shipping to me and back plus pay a re-stocking fee. Needless to say I wouldn't buy another and wouldn't recommend it to anyone else. Read LessRead less about I really wanted to like this handguard
