So I purchased a pistol buffer tube from bkingsfirearms a month ago, finally got time to build my lower, and when trying to tighten it with a wrench, I noticed it (castle)wouldn’t exactly line up with the notches on the wrench, and furthermore it seems as the tube is an extremely tight fit on this tube compared to the kak pistol tube.
This in’s my first complete pistol build, am I missing something that’s different with these types of tube compared to carbine? I’m assuming I received a commercial tube? Thank you

Sounds like it’s commercial. They’re only like a mm thicker I believe but I’ve done this exact same thing with the same problem
