For sale is a  SiG Sauer Complete M400 FDE, factory 11.5 inch barrel, it came from the factory as an M400 with  factory gen 1 sig brace and buffer.


Got it in 2015 brand new, I recently upgraded many parts to get the gun running at high speed. Upgraded full auto BCG, new buffer tube, new buffer h2, sb tactical 4 position brace, and Atrius super selector installed.


This was not a drop-in part on sig, it required fitting. It runs well and fast. Its had 100 rounds thru it for testing only.


I CAN SEND YOU A DEMO VIDEO OF the TEST FIRING.


So essentially this has a three position safety. Position 1 is safe, position 2 is semi-auto, position 3 is about 650-700 rounds a minute of fun. If you are not familiar with how a super safety or an frt works I'm happy to answer any questions.


it's got Sig reliability and the three position super selector makes this thing a whole lot of fun.


Comes with all the original factory parts, 3 -fde 30 round magazines, and s soft case.


I will consider some trades but please reach out and text me with any offers. I can be very flexible on the cash price so MAKE YOUR BEST OFFERS, worst i can do is say no. You wont hurt my feelings by offering me less than asking, might just say no.


text me and I can send you a video of the sig in action.


I can also provide you any other photos or answer any other questions.
