[ARCHIVED THREAD] - Who Manufactures Hodge Defense BCG's?

Posted: 12/7/2018 3:25:13 PM EDT

I am trying to source a Hodge Defense BCG. I have every other Hodge Defense part except that. I believe his BCG's are manufactured for him by a third party. Until I can acquire the properly marked one, I'd like a spec one to put in my rifle.

Can anyone tell me who he sources his BCG's from?

Thank you for your help.

Specs, according to J. Hodge:

"BCG: M16, 9310 HP, MP tested, shot peened, staked, nitride."

Doubt he will tell you his source. May be wrong?

A little more info from J. Hodge:

"Then we have the BCG. Nothing, really, is going to make a gas-ring more than a gas-ring, and the same for an extractor spring, so obviously there are wear items. However, the QPQ BCG's I have used in the past are all VERY slick internally, which theoretically should cut down on wear to the rings. That said, QPQ cam-pins show a lot less wear in my experience than Chrome lined, or regular Phosphate cam-pins. Further, QPQ on steel when dry, is more lubricious than non-QPQ steel on steel action. One thing learned during NSW/DEVGRU testing is that a properly lubed bolt lasts longer. Why? Because the axial forces between the bolt lugs and the receiver extension are lessened secondary to a lower coefficient of friction on the parts if you run the gunwet instead of dry. Thus, theoretically, a QPQ bolt is less likely to shear lugs than is a non-QPQ bolt, all other things being equal, as the coefficient of friction between QPQ and Steel lubed or dry, respectively, is lower than steel/steel lubed, or dry, respectively. Now I fully grant that this is theory, but it does have science to back it up. Same for the cam-pin wear situation. Wear creates slop. Cam-pins have a +- 0.0015" OD tolerance, IIRC, for a reason. The more slop, the more shock, and when you have wear, you get slop. Stop the wear, stop the slop. The cam-pin not wearing should preserve the interface between the cam-pin hole and the cam-pin, and prevent shock loading of the bolt at that critical junction, later in the BCG's lifecycle where typical cam-pins will have worn. Again, this is theory, but I personally know of several QPQ BCG's with thousands and thousands (well past 10K) of suppressed, full auto, etc. type rounds on them, and they are fine. Underlying heat-treat and proper dimensional specs are THE KEY to these types of components, though, to be fair."

I know he has put the clover leaf on Radian BCG at one point

Microbest probably.

Someone in an older thread said Azimuth Technologies. They're the company that makes the "enhanced" melonite bcgs.

Jim Hodge didn't say that, but he did agree with it.

Azimuth milspec QPQ bcgs meet the spec outlined by him for his BCGs, and I would look there for a similar to Hodge OEM bcg.

Not unless radian also used his supplier.

My bad, you are correct on the quote.
