    The barrel nut works great with my upper. It secured tightly in place with no major effort. Securing to the Aero handguard I have was no issue either. As for shipping. Everything came in an orderly fashion. Even with the pandemic, my package was at my door in a few days. I highly recommend, not only the product but this company.

  • Precision...

    Posted by Joe on 1st Jul 2019 not just in the company name. Building a "no handguard" 9mm AR pistol with the nut exposed, so it has to both look good and get the job done. While not the intended application (it's meant to mate with an Aero handguard), this slim, solid part provides the perfect balance of form and function. Wing Tactical had the best deal around.

  • Fast delivery.

    A well engineered Solution to the Problem of Timing the Gas Tube hole. Eliminates Over tightening.

  • Very good quality and a good design.

    Truth is, you shouldn't have to buy one of these devices. It should be included with the forearm. However, it is well designed and well machined. So far, I'm finding that Aero is the best bang for the buck in the AR arena.
