I think people get a bit too wrapped up around the roll mark. A lower receiver is just a fixture to hold the other bits in alignment. The forgings for MANY brands are all coming from a few foundries. If Anderson had a 50% fuck up rate- which they certainly did not, you’re still money ahead buying one of them over most any other brand.
I mean, if expensive stuff makes your dick hard, rock on.
I have one Anderson lower. It’s on a rifle I used for PRS. Matched with an Anderson upper housing a JP barrel that is an absolute tack driver, it was not the receiver set holding back my scores.
Are there “better” receivers? I’m gong to need a definition of “better.” The receiver I have has not been a failure point in any of the recreational/competition shooting I have used it for. All of the holes align properly for all of the bits that it houses.
Are there receivers with more features? Yes. Are there companies that make receivers with a much lower rate of fucked-up-ness? Yes. Is a $400 receiver that functions correctly “better” than a $49 receiver that functions correctly? Not in my book. Hell, I’ll go so far as to say that one $400 receiver that functions correctly is worse than three $49 receivers that function correctly and 5 that do not.
