Hi,

I ordered a complete bolt carrier group that I was told was a Daniel Defense. It's an AR15 not M16 bolt with no markings. Bolt is marked E or possibly F underlined. Finish is phosphate, keys are very well staked.

Should it be marked DD in any way?

Thanks

I've googled that a little and it would seem that F underlined bolts are maybe FN produced, probably not, but there seems to be very little actual info.

where did you order it from?

mine is full auto and is marked like this with no markings on the bolt itself:

It actually came OEM with a rifle from a nice brand. My guess is they they just were getting unmarked OEM DD BCGs but I was curious.

The barrel is definitely DD.

That's the problem with various production runs of DD or BCM... Some had no markings.

I'd shoot it and not worry about it.

That was the plan.

Not really worried, just, I'm one of these people who is curious about things and likes to find out details of the way things are.

That's how mine looks. I don't think DD makes them in-house anyway, so I wouldn't worry about it. Probably the same BCG, but the newer ones are just laser engraved.

Really? I thought they did make theirs in house.

I've heard BCM doesn't DD does.

I am pretty sure DD makes theirs in house.

Let's leave the speculation. I believe that real FN bolts are marked MP F. Not sure about the underlined F. I seem to recall some time ago that PSA was selling some bolts like that.

In the photo in post #4, does your bolt carrier look like the middle one(semi-auto) or the bottom one(full auto)?

If it's the semi-auto, you did say it was an AR-15 BCG, I would be curious to know if DD ever sold phosphated semi-auto BCGs. I know they sold some chrome BCGs that had semi-auto carriers.

It's definitely a semi-auto.

I can't promise you, but I think that is an FN bolt, and IIRC, FN machines bbls and bolts for a number of other companies. Again, no promises, but I'm fairly surethis is the case.
