Looking for 1/7, 16 inch, chrome lined, mid length barrel
I'm in the market for the above noted barrel (or upper), light wt, middle wt, or gov't profile.
I bought a BCM upper, but it is going back due to chambering both my new Clymer 5.56 No Go Gauge, and my Forster .223 No Go Gauge (ain't Brownell's wonderful!) and the bolt was still sloppy over the chambered gauge.
I'm looking for backup. Who can report dealings with other outfits such as Denny's guns, CMMG, Sabre Defense.......................or any others.

So you are using a go/no go gauge like this one:
http://www.brownells.com/aspx/ns/sto...DSPACE%20GAUGE and the carrier is completely flush with the end of the upper receiver???
Where your story becomes even more interesting is the comments about the vendors at the gun show not liking BCM. I am curious what kind of comments they made? Have they ever seen a BCM product (especially since NONE have been available for more than a year). So how could they have a negative opinion of a product they have never actually seen?

Grant, the specific gauges involved are:
Brownells P/N 184-000-036 (Clymer NO GO for 5.56) Dimension is etched on the side of the gauge, but I don't recall what it is. (I'm at the office)
and
Brownells P/N 319-223-467 (Forster NO GO for .223) for this gauge the dimension is 1.4666 in. as noted in the catalog web page.
The bolt(s) were stripped, gauge inserted into chamber and the bolt(s) inserted and rotated by hand. Lots of slop on the bolt closed over the NO GO gauges. I don't own a field gauge.
Vendors at gunshows tend to be similar to vendors at carnivals. You assume BS until data shows otherwise.
As to BCM, yes I have contacted them by email prior to posting here. The upper is new and unfired (by me). I got a pretty quick reply requesting I send it back. I posted here in part to get some feedback on the reputation enjoyed (or not) by BCM in the community. They seem to have a pretty good one. I also am interested in who else to do business with if BCM can't (or won't) correct the issue in a timely fashion.
I'm an "amatuer" gunsmith (mostly self taught) and full time engineer (education and vocation). I think I'm competent on the basic stuff. Measuring headspace is pretty basic.

Re: NO GO gauge for 5.56/.223
Grant:
What is the dimension on the NO GO gauge you used to measure the headspace on the upper shown in your picture....... I ask this question due to the gauge you referred me to in the Brownells catalog.
The Forster NO GO Gauge listed at Brownell's Website is 1.4666 in. As I say, I'm not at home to see the etching on either of my NO GO gauges.
Am I to understand that BCM chambers their uppers that loose intentionally????

Re: Headspace on my BCM upper

An Update:
I stopped by a buddy's place and he had a Forster Field Gauge at 1.4696 in. This gauge will not allow the selected bolt to even start to close. First I used my hand technique as described above. Then I put the stripped bolt into a carrier and again it would not close. Looked like your picture
I think this is a good thing

Re: Adventures with my BCM upper
Folks, sent the upper back to BCM yesterday per their request for it to be checked out.
Based on what I learned here (in spite of myself) I expect it will check out fine.
Anybody that was thinking about the purchase of one of their uppers, I think I would use this as a big thumbs up. They are really motivated to make VERY CERTAIN that every thing is "right" with the product.
As a aggravating note having nothing to do with BCM: Shipping anything associated with a firearm has gotten to be a major PITA!!! It just re-affirms my previous opinion, if you can call it anything other that a firearm component or part, and make it stick, you are better off by miles.
