Gunsmithing Whats the possibility of an AR bolt head on a actual bolt gun?

[Travis224]

Was kinda curious, the bolt that locks in the barrel extension is a big reason why ARs shoot so well, has anyone ever thought about why a guy couldnt put an AR bolt head on a say remington bolt and machine the action to accept a barrel extension? Some guys already put savage bolt heads on remington bolt bodies...whats feasible and what isnt? I am guessing it would mean a very short bolt throw 30 degrees or so, right? Just very curious..

It would be easier to leave the gas system off an AR and fit a bolt handle on the carrier. Sounds kind of frankensteiny to me.

30° bolt lift would make cocking a traditional bolt-action striker very heavy due to much less mechanical advantage.

Same goes for primary extraction.

Check out the Mauser 96 American. Stoner locking lug system in a straight pull bolt action. Sweet rifles, too bad Mauser is no longer around :/

Remington does it on their MSR. 3 lug bolt head and a barrel extension. Works fine. As stated a 6 lug bolt head would be a problem.

The Mauser M96 (new production) is an interesting design. Only wish they had kept the M16 type pinned extractor versus the Sako type.

I made a .45acp mini bolt action I made with an ar bolt and extention. I'm doing a .300 blk one when I get time.

Now, since it seems that some possible hurdles have been conquered, is this a possible equal to the accuracy that is built into the AR design?

 

[Delta4-3]

Yes it is.

Adding lugs is not a new idea - you reach a limit in mechanical advantage at around 4. Beyond that, and it's annoying. I don't buy that the AR's bolt design is that big a deal when it comes to accuracy, so I think you're barking up the wrong tree. You wind up increasing complexity and cost for dubious gain.

Another way to think about it is you can't balance the bolt thrust across more than three lugs with any sort of reliability, so more than that is going to be superfluous, and may even increase the difficulty of getting a good lockup. The AR has all those lugs because it has to in order to achieve a short rotation.

Tag. Good infol.

If you want more locking lugs, you could get a Weatherby Mark action. Nine lugs. Three rows of three.

I have yet to see ANY ar style rifle (bolt desgine i mean) out shoot a well build 2 or 3 lug bolt gun.
I highly doubt that most people can shoot a true 3/8 MOA rifle to its true potential anyway.
If a faster cycle time is what your after i'd think more practice is needed , I've seen guys cycle AI rifles pretty damn fast with proper training and practice
