Well then I'm sorry...maybe make the pathfinder, and 390 pages first then add it, so it doesn't seem random lol.
Also, the reason I asked for a source is because even though that information is technically wrong, Bungie/343 Industries has screwed up before and it might actually be canonically correct.
I didn't say you didn't have anything useful to add, just that that particular information you added was incorrect. I have no idea what you tried to add to the UNSC Army article, and to be honest I probably don't know enough to verify or refute any information you did add to that article.
However, I work on and shoot firearms (in particular, AR rifles) as a hobby. I tend to go over those articles and make sure that they are correct from a technical perspective. That is why you ran into me when editing the BR55 articles.
Your information is not solid. I told you why.
First of all, fix your tone. No one is getting "bent out of shape" except for you right now. Go see the talk page and read why I reverted your edits.
Seeing as 7.62 NATO is quite a bit longer than the 9.5x40mm, it will take more than a simple bolt and barrel switch to interchange rounds; the receiver would need to be lengthened because the magazine well isn't long enough to feed 7.62 NATO rounds.
You had no sources and it seemed like you were just randomly added things. Plus you deleted the conjecture markers and those need to be there.
