Will this work on a new frontier c5 build?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on June 13, 2022

You would need to use a 1913 rail adapter that provides a location for a mil-spec buffer tube to be installed to your pistol. Once installed, you can use this Guntec USA AR 9mm Cal Pistol Buffer Tube Kit. Although the buffer and spring would not even be needed.

I purchased this for my AR-9 and it’s extremely difficult to pull back. It forces my LRHBO forward. Is this normal?
