I'm gonna be honest here.
XXL, I keep seeing you post about the cheapest parts that are out there. Continually. With your incessant bargain shopping, and finding the cheapest parts that are out there, you have to expect some things.
This falls in line with the "Machinist's Rules..."
Don't expect your parts to perform like higher priced, high quality parts. That's just a sad fact of gun-world reality. It really is. Don't expect your 16.5" $100 rail to perform like Daniel Defense rail. It just won't, most times.
This is continually a thing with you, posting up super-cheap parts, and asking questions about them afterwards, and sometimes even beforehand. We can't predict how your inexpensive, no-name part will perform, and we can only shake our heads when that same part doesn't perform like higher quality parts do...
If you want predictability based on past recommendations... "This part does this..." ...then stop buying the cheapest, closest copy you can.
I hope you don't take this wrong, but I may be wrong on that... If you want your rifle to perform, then you need to toss some proven performance parts at it. Don't expect anything different, when you're doing what you are doing...
