Good morning INGO.
I had some help building a AR15 chambered in 450bushmaster. I went with a SilencerCo receiver set. Took her to the range and im sure I have two issues.
#1 and most obvious....is the ejection port is too small. It is not a "XL" upper
Is there anyone local around Indianapolis that could make the port larger, and still keep my upper in good condition?
#2 I may have to adjust the gas pressure, or work on the feed ramp. But I want to start with the port first.
