"M-4 feed ramps"? Is this just a barrel or an upper (if upper what all comes with)? Where is the gas port location, what size, and is there a chamber guage? Also, what is the twist?
Thanks, looking forward to the pics.
Edit for one more question. Do you know if the chamber was cut with a Clymer (40) or a PTG (35) reamer, and how the difference will relate to 300 BLK converison, if any?
