Anyone have experience with them?
I realize systema is quality, but is there a better solution to their gearbox (i.e. 1 or two of the pieces are made better by another company?)
Or is dropping the sytema box in your gun pretty much a final solution for upgrading the gearbox?
Also, I found the gearbox for the m4 series at $230ish
I noticed this post was missing the word gearbox...so....Here it is, gearbox
