Questions & Answers
Does this need a traditional buffer system (so buffer tube, spring, & weight)? Or is it bufferless so you could utilize a folding stock/brace with it? Expert Answer

The FM Products FM-9 AR 9mm Forward Charging Upper Receiver w/ Micro Brake still utilizes a buffer system like an AR15.

Did not come with brass deflector (as pictured on website) by J. K., Verified Owner, March 8, 2024
I have owned a few FM Products 9mm uppers. I really like the side charging feature and the delrin/polymer insert where a “standard AR charging handle” would be to prevent gas to the face (especially good if you’re planning on going suppressed). It wa...
