98Z5V Posted July 30, 2019 Report Share Posted July 30, 2019 Check your bolt. Insert your bolt, and rotate it. If it doesn't rotate - punch that Lawyer Pin out. Heard from @willbird that used a SIG bolt, that his bolt rotated with it in there. Mine didn't, with a ToolCraft bolt. There's an external dimensional extractor difference between the SIG bolt and the "others" apparently. Lawyer Pin. "decommission these barrels and sell them" says the lawyers. This is what they came up with, I guess. I punched mine out with a roll-pin punch that was slightly smaller than the OD of the OUTSIDE of that visible pin. You MUST punch it INWARD. You'll never get that thing to punch through if you try to punch it OUTWARD, from the inside of the extension. If you try that, show me the pics of the destroyed extension, brother... I punched mine right out, inward, after my TC bolt didn't rotate. Fuk that thing. Think about it - how's CDNN selling us a $450 barrel for $50? You think they do NOT have a profit on these things? Damn right they do. They're making money, and they got these barrels cheap. SIG had to come up with something to blow these barrels out, and make them "inoperable" - we just beat the system.

This is what they came up with, I guess. That pin is there to back up the extractor in a catastrophic failure. They put it in the M400 as well. Mine has not been in the way for any of the bolts I have, have a Toolcraft on the way now so it will be interesting to check. Quote Link to comment Share on other sites More sharing options...

Albroswift Posted July 30, 2019 Author Report Share Posted July 30, 2019 I noticed the pin in my 308 barrel as well, didn't notice it in the 223 barrels, have to check again.

willbird Posted July 30, 2019 Report Share Posted July 30, 2019 I grabbed one of the sig 400 16" non threaded, that is a steal at $49 shipped IMHO :-). Thinking to chop it down to somewhere between 10.5 and 12.5 to build a 5.56 mini me of the 7.62 sig shorty I'm piling parts up for :-).

I am curious if there are two different barrels, Sig made a gas block change at about the same time they were producing the pistol version of the 716, possibly the port location changed. I need to mock up my second barrel and see where it hits. I am also noticing Sig headspaced these barrels tight, a BRN-10 bolt failed a no go gauge on most of my barrels but passes on the Sig barrels.

When I bought my PM400 it was pointed out as a safety feature on their website, it is not mentioned now. Quote Link to comment Share on other sites More sharing options...
shooterrex Posted July 30, 2019 Report Share Posted July 30, 2019 Both bolts I have lock in and headspace ok . Guess I'll leave the pin in. Quote Link to comment Share on other sites More sharing options...
RedRiverII Posted July 30, 2019 Report Share Posted July 30, 2019 (edited) How much spin, or turn should the bolt move ? Mine does a 1/4 turn. Does the empty hole make a difference? My 6.5cm barrel has neither a hole or pin, it does have the index pin. Never mind, my 6.5cm lets the bolt rotate 360.

What he said. Both the Toolcraft and the JBO special went in and rotated properly with the pin in the 223 barrel. Located dead center over the extractor. Took the bcg out of the Anderson AM10 because I haven't got one yet for the 308 barrel yet operated fine.

Albroswift Posted July 31, 2019 Author Report Share Posted July 31, 2019 Must be some other reason they are going for dirt cheap. Maybe buy a couple more just for safe ballast Quote Link to comment Share on other sites More sharing options...
Albroswift Posted July 31, 2019 Author Report Share Posted July 31, 2019 Also, looking at the hole opposite, it has bluing and cosmaline in it so my guess is not drilled after the fact. Quote Link to comment Share on other sites More sharing options...

I had figured what the heck, no harm having an extra barrel for my P716 at that price, got to comparing things and realized it was just a custom gas tube away from being a DI gun. 98 pointed me to White Oak Armament and the mass enabling began Quote Link to comment Share on other sites More sharing options...
RedRiverII Posted July 31, 2019 Report Share Posted July 31, 2019 Arms outstretched in front of body, parallel to the floor, palms down, he mumbled. " Must get barrel, me need barrel, must get barrel. No use for it, but everybody is doing it. Must get barrel." Three times I was sleep walking last week, 3 barrels and counting.

The fact that you make it well known that you have a short barreled AR 308 didn't help matters! Actually.......I have 3, well 2 AR's and a FAL. But who's counting? Counting is rude, whether it's beers or rifles. It'll be interesting to see what you build with it my brother. Quote Link to comment Share on other sites More sharing options...
