Anyone using these? Just looking for a standard, MILSPEC BCG.

Mostly I've been using Toolcraft and Colt, thought I'd see what else Arfcom likes.

PA has the NP3 ones on sale right now.

I’d snag one of those.  They’re fantastic.  

For regular phosphate, they’re all the same assuming you grab one with good specs from a known supplier.

Probably made by toolcraft.

SOLGW BCG is GTO. Microbest makes them. Realistically they should have a little more quality control since they individually test every BCG instead of batch testing.

I have one in one of my builds… It’s been solid and does what it’s supposed to. Can’t say or ask anything more.

lol

I wish people would stop trying to read tea leaves to determine who OEMs a particular component. What matters is whether the company that sells them has specced things correctly and has a good QC process to weed out any bad parts, whether made in-house or elsewhere.

For standard phosphate BCGs, I'd trust anything from Colt, BCM, or SOLGW. You could buy a Toolcraft or Microbest but you also might get something that was or would be rejected by QC at another company. If it works, maybe the machining is rough so gas rings will wear out quickly.  Maybe it has really loose tolerances but works because the barrel is overgassed and can handle gas leaks. Maybe you get something that's perfectly fine. Again, it's not that the above companies can't produce a lemon, but you're more likely to get a high quality product.

Just off the top of my head, Microbest in particular has had QC problems for a couple years.

What tea leaves am I reading? The owner of SOLGW has literally said Microbest is their OEM.  A SOLGW BCG is a Microbest that they then proof test and put through their QA/QC process.

I'd be interested to see when and where he said that. There's an SOLGW employee here who's said that they haven't used barrels manufactured by Ballistic Advantage for years even though people still repeat it.

Maybe I misunderstood what you were saying, but a lot of people equate physical manufacturing facility with quality.

I have had good luck with AO Precision BCGs which I believe I bought from a company called Danger Close.

They were affordable and shipped quickly. Good customer service.

He has said it on multiple Primary and Secondary modcasts and other podcasts that he’s been on. I also completely agree with what you are saying , just because one oem makes something for company y it doesn’t mean it’s the exact same product as company x. It depends on what both companies are willing to pay for the specs they want and the qa/qc.

@SOLGW_jim want to settle this debate
