few make their own barrels but will cut/tool them, as bcm does
2 companies make 99% of AR mkt bcg so hard to fault anyone on that. Shit half this other boards actually think Toolcraft makes bolts!
receivers etc, they have contracted to machine shop with their own specs and their qc is industry regarded as one of the best
Only 2 companies do chf in house for 99% of the mkt.
Look, I'm not a BCM fan as whatever they do on the milling and lathing machines isn't working or wasn't working for me and many others in the regards of accuracy but trying to hammer a company cause they don't make all their shit in house is monumentally retarded given the state of the industry.
took this from the hide as they have reps there and m4. simple search would answer most questions.....
'BCM has significant investments in manufacturing machinery and equipment. (Spent later part of last week setup up a new grinding operation)
BCM has significant investments in all our own tooling. (fixturing, QC, uppers, lowers, charging handles, handguards, lower parts, stocks, grips, etc, etc, etc, … I know I am missing a bunch)
BCM has its own engineering department and holds a number of patents with dozens more applications at the US Pat office. (IMHO our engineering dept is the best in the industry)
BCM has its own prints, specs, data package on all parts with tolerancing to the mil-spec or often better.
BCM has one of the best QC dept, procedures, and track records in the AR15 industry. We have made significant investments in equipment for this as well. Some of the QC procedures and tooling BCM has created is now being implemented by multiple USGI contractors for .mil sales. (BCM built the tooling and/or supplied the procedures and prints)
BCM makes OEM parts for some of the biggest names in the industry.
BCM family (of companies) is operating in multiple locations right now, maybe more in 16?
