Reviews & Ratings for Watchtower Firearms .308 X7M Handguard — 1 review — Page 1

Nice design and function. However, barrel nut is not aluminum as claimed, out of the box the barrel nut handguard screws thread protruded deep underneath and required deburring. I made a mistake by tested on the proof research barrel for fitment and the threads scratched the carbon fiber before being seated flushed onto the barrel extension that required a little bit of force. Deburring all the protruded thread fixed the problem however the barrel nut required a coating or it will rust at the deburring areas, which is more work. Observing many F1 Firearms AR style rifles with Proof Research barrel installed, I would assumed that this little detail would be addressed prior to sending the products to customers.
