The saga of the missing barrel nut (aero saved the day) - Aero Precision AR15 Standard Barrel Nut

This Aero Precision Barrel Nut was a necessary purchase after realizing the TacStar Carbon Fiber Handguard I bought didn't include one. The quality is exactly what you expect from Aero: impeccable fit and finish, and it threaded onto my upper receiver perfectly, allowing for proper timing. It ultimately locked down the entire front end of the rifle, solving my problem. I'm rating it 4.5 out of 5 stars because while the product itself is excellent, it was a component I shouldn't have had to buy separately. Highly recommend this for any AR-15 build where a standard, high-quality steel nut is needed, but wish it had been included with my handguard originally
