No ideas from anyone?

I think he's about ready to take a mil-spec bolt and round the outsides of the lugs.

Professional Ordnance Carbon 15 bolt

My boss' brother has one of these with a broken bolt and we're trying to find a replacement.

First off, your asking for something for nothing.

I don't see why it couldn't be done, I've made a few 7" 30-221 barrels.

If you start with that, I'm sure you could get supersonic loads to run without a problem, I doubt subs would be easy.

I also have no idea how those are actually built so that might be a hurdle...

There is a lot going on there to make it difficult, one of the main things is the short gas system, the main spring would have to be separate from the gas system making it big and ugly.

He may be correct, however the number of cycles that the bolts see is usually sub 100,000 so it is hard to say. - it depends on the stresses

C158 is some super hard stuff in the case but softer in...

The best way to do it is take a rifle gas tube, calculate the length you need(straight is approximately .025-.050" longer than it will be bent), chop it, turn it in a lathe, or you could try the file...

I've only got a few barrels out there and I know the answer is no. I think the better question would be to ask if anyone is having any issues or concerns with running the whisper full auto.

I'm sneaking up on the port size for him so he has a better chance at running supersonic rounds, last time we were out(first stab at the port diameter) it ran 75% lock back so I opened it .004". It...

He has a carbine gas port so it'd have to be completely moved.

I can make you a custom gas system that would work at 8" if you'd like. I can't re-finish the barrel though(black). PM me if you are...

I haven't proven this but I'm pretty sure velocity also plays a roll in this.

One way you could test it is shoot that bullet at 1250fps and see if it stabilizes, this would give the bullet an...

Now that I think about it some more, It should be feasable with an adjustable block but it might be finicky. I mean think about how finicky 5.56 is through a 7.5" barrel.

If all goes as planned,...

I didn't have much to go off of with quick load but it looks like pressures will be at least 1.5x on a 125gr bullet traveling 1600fps out of a 7" barrel.

I have a bunch of 160gr bullets that...

I think it is an evolution, not being able to shoot supersonic rounds will be a turn off for some. I'll be making up a fixture for making gas tubes soon.

Looks good Spook,

Keep in mind that the shorter gas system is probably not optimal for supersonic high pressure rounds, I haven't run quickload on it but I bet it would have too high of pressures....
