BCGs?

[Trumpet]

Alright,
So it's been a while since I bought any (last I bought were a couple "Super duty" from Dennys guns). What's a good "go-to" BCG now? Toolcraft, SOLGW, Sionics? Not looking at fancy high-dollar BCGs.

Toolcraft has always been gtg.

All are good. Some people prefer phosphate over nitride over NP3, etc. Personally, I like phosphate with chrome lining with a 158 carpenter steel bolt.

I thought maybe you were going back to boot camp

 

[Trumpet]

Oh, I still have mine

BCM and Daniel Defense are my go to carriers. I’ve generally found BCM carriers for $10-$20 less than the DD carriers.

You can do fine for less, but I trust their QC. I would equally trust a SOLGW carrier.

Avoid the fancy coating nonsense.

I have always used BCM for my builds.

On sale at AIM for $170

Toolcraft or Aero Precision for me. Aero always sends me emails with their BCGs discounted.

That is exactly where my mind went for that acronym. I couldn't come up with anything other than "birth control glasses" until reading through the thread and seeing Outrider's search link that I had my "oh yeah" moment.

I still like Colt BCGs a lot.

If purchasing a complete BCG, I lean towards BCM. If breaking down further and just talking about bolts, my preference there is JP. I've run others (Radian, Toolcraft, Rubber City, Armalite, Stag and probably one or two other manufacturers) and only encountered short headspace or other concerns on two of those brands. I'm confident there's other great options outside of my preference. Working with SOTAR in the past, no matter what I run, I'll run through a portion of the checks which you can see in his BCG dissection videos.

For an AR10 (308/6.5creed) - I only run JP bolts there.

I still like Colt BCGs a lot.

I'd run Colt BCG's all day. The tricky part is finding them at a decent price. Literally no reason to pay $250-$300 for a Colt BCG when a DD or BCM can be had around $200.

Tool Craft gets the vote
still have some Chrome "Colt's" from decades ago.

At this time anything made by Colt or Microbest is what normally passes my testing with flying colors. That can always change.

Microbest is an OEM for several manufacturers such as SOLGW, Sonics.

I avoid NiB and Nitride due to issues I have repeatedly seen.

I often wonder what the real difference is on some of these components. I don't have any high end or name brand BCGs. In the 4 that I've "built" (I've only built two from the ground up) I have:

DelTon - phosphate
PSA (x2) - NiB
Toolcraft - NiB

Everything goes bang. I've never had a malfunction or anything that would indicate that there's anything "wrong" with any of them. Granted, I don't push any of these rifles very hard, so take it for what's it's worth - not a lot - but if everything is made from carpenter steel, and everything is spec'd to within decent tolerances, how much does it really matter? Even high end stuff can break.

I know a person can sleep better at night knowing they have a BCM or Aero BCG, but for now I'll be fine using Toolcraft or PSA, although I might bump up to an Aero for my next one.

Chad, had I known then what I know now based on what you've posted, I might have avoided the NiB when I ordered the last ones. I liked the idea of them being easy to clean, but I don't like the idea of breaking and poor tolerances, although I have had zero issues with the 3 that I have. My next ones will be either black nitride or phosphate.

If your C158 bolt isn't individual HPT and MPI it has about a 2-3% chance of early failure. This is a known failure rate for proper bolt steel. It's why HPT is done, to find the bad ones before they make it into the real world.

Just because a bolt is marked that it has been high pressure tested and magnetical particle inspected does not mean that it was individually done.

Most people don't shoot their guns enough to see failures so manufacturers push junk knowing few will fail based on most peoples shooting habits.

Price and brand is not an guaranteed indicator of quality or durability.

Colt BCGs for $180

AO Precision has been good. Phosphate, no logo, reasonable price.

I still see them on GB under $200.

Colt BCG are no better than most other mil spec BGC

You can get an AO Chrome/Phosphate carrier with 158 CS bolt for $90

A Toolcraft same finish for as low as $90(blem) or $130 first quality.
