BCM VS Colt BCG

“Quantity has a quality all its own.”

Sorry but I would rather have 2 Microbest for $200 than 1 BCM or Colt.

Since someone mentioned it, even though it wasn’t in the OP’s question.

I’d also choose Sionics over Colt or BCM.

They gauge excellent and more consistently inside and out. They also include well staked OCKS.

For back ups, I can't argue with that logic. I do like my primary gear to be BCM or Colt.

Makes sense, all Sionics products that I’ve used have been top notch.

As alternates I would also suggest Sons of Liberty Gun Works, Daniel Defense, Black River Tactical on the high end. For a lower price point, I’ve been really impressed with AO Precision mil spec that I’ve sourced from Right to Bear.

I just got in a Sionics NP3 BCG, headspace checks good, haven't messed with it much more than pulling the bolt out and lubing it up.
The phosphate one is $20 less than a BCM and uses ocks screws.
Lifetime guarantee as well.

SIONICS BCG are awesome, I have an older one pre-OCKS and pre-phosphate extractor and a newer with the improvement, both have been 100% as have my Colt, BCM and SOLGW BCGs.

I was in the "wherever possible use Colt" camp until I had a brand new Colt BCG show up out of spec from Brownells last year. Of course they took the return no issue, but still. The issue was in the cam pin slot. Couldn't get the cam pin out, the bolt wouldn't rotate far enough. The bad part is I didn't pull it apart before trying it. I assumed it was good to go being a new Colt BCG. The gun hiccupped once or twice when sighting in, but I figured it was the mag I was using and didn't pay it that much attention since it was more of a precision build anyway. It cost me a deer because I got a "click" instead of a bang. Tap racked and got a second click. By that point the shot opportunity was gone. It was a very cold morning and at first I thought it must've been cold lube preventing the bolt from fully seating. I got home and went to tear everything down to clean and lube and that's when I discovered the issue.

Doesn't mean all Colt BCG's suck. Just that anything can have issues.

FWIW one of my guns has a Colt BCG and the other has a Brownells Nitride. Both work equally well.

Not to add insult to injury, but I'd never put a BCG into live fire without a tear down, inspection and lube.

Yeah I hear you. You see enough good in a row, you get complacent. I did.

The few Expanse Carbines I saw had 14.5” Socom barrels and BCGs with C stamped carriers and extractors.

You need to stay out of the Colt threads.

If you actually knew half what you 'thought' you did you would know that those did not appear until the very end of that series and were rare as hens teeth.

Those were the exception and not the norm for that series and produced / cobbled together for a few months vs being produced for a few years.
