There are people on this forum that will tell you brand X is just as good as brand Y, but will never explain why other than saying "well I have 100 flawless rounds through mine without an issue." Those people are clueless. Everyone harps on the AR being like building Lego blocks, but it's really far from it, especially if you tend to use cheap parts. Just because you hear that brand X has parts made by brand Y, does not mean those parts are the same. Often times they are worse, but occasionally they will be better. When they are better it's due to the company having those parts made to their specifications performing additional checks and tests on those parts to ensure they meet a set of standards. In a previous thread, I posted videos of DC Machine, where the majority of PSA parts are made. That company is pushing out 2000+ receivers a week, but only check a small percentage of those parts leaving the shop. This leaves a greater margin for errors. While you feel you're getting a deal, you won't know until you check it. Having the right tools to check these things is important.
