Q,
I noticed something on the broke lower, maybe you can explain to me. The hole for the auto sear: was that an AR15 or a Gov't M16? The reason I ask is that I have heard of this type of failure from a poorly done full auto conversion, and if that is the case, it may not be Vulcan's fault this time. I don't like Vulcan/Blackthorne/whatever any more than you do, but this may be the case this time.

The weak link in an AR-15 receiver is where the photo shows. In the bolt it is where the cam pin is drilled. This is true regardless of who makes them. The best manufacturer on the planet cannot add stock to a weak area, and have it fit the weapon.

I am still kinda beleiving the owner may have botched up a full auto conversion, and milled away too much material.

If any gun is screwed with by an individual, then the manufacturer is automatically off the hook.

Yeah, I haven't heard of any Vulcan military rifles in any units. Special Ops (Seals, Green Berets, etc.) uses HK 416 or an LWRC variant. FN currently has the contract for regular military M16's. So the only other (legal) option is if they got a PD contract somewhere. The stamping is blurry on the pic, but if I had to take a guess, I would say the original stamp says SAFE and FIRE. It doesn't look like a polymer lower either.

thanks very much to everyone for all the info. i still don't have an AR-15 in my collection yet and when and if i do get one i will most likely get a DPMS chambered in 6.5 Creedmoor.

Sorry, 2a, I don't know the story on either of the pictured lowers. Just that they broke. I agree they both look like alloy not polymer. I had not noticed the hole for the auto sear before. I may be wrong but think they are two different lowers. If so we don't know if the one with the auto sear hole is factory or not since we can't see the other side.

In that case, I am going to run with the theory that it was probably operator incompetence/abuse in a full auto conversion on at least one. Despite their website claim to the contrary, I can't see any government agency purchasing full auto guns from them with their track record, unless it was some Barney Fife type guy in a small hick town PD doing something underhanded to get one to play with at his dept.
