POF fluted chamber

My buddy at work was showing me this fluted chamber neck design that POF is using in their new AR platform. Apparently it was an old idea used by HK and POF is putting a new spin on it and giving it a go.

Maybe im too closed minded, or just plain traditional but i do not like the sound of this idea. What do you guys think?

In an AR platform rifle, especially one you will not reload for I can see it being a great idea.

I cannot see how it would have any positive effect on accuracy and potentially see it could hurt it.

It seems like a really good way to screw up your brass for reloading.

Most of the time if you are having a problem with an AR it's related to extraction, or debris in the chamber preventing proper cycling so for reliability in a fight, it makes sense. I can't see it being a benefit otherwise.

Re: POF fluted chamber

I think you make a solid point in relation to ar's and extraction problems, and i didnt consider how that would relate to a combat situation. In that scenario it really starts to seem like a good idea.

I was really wondering how you would clean those tiny grooves and what would happen if they were not cleaned properly and carbon was allowed to build up. Could it have the reverse effect and make a shell harder to extract?

Fluted Chamber is regarded as a plus for a battle rifle.

No more of a problem than a dirty chamber. A sharp dental pick would easily remove carbon or debris.

With any military rifle one of the critical elements is how well they can perform when muddy, sandy, wet, dusty etc which is why you find ways to create channels and grooves for crap to move to in order to keep it from gumming up or clogging the operating system.

This is actually where the idea for fluted bolts came from. Of course a fluted bolt is also less likely to freeze and stick to the point you can't operate the action in sub freezing wet weather..

I guess there is no reason to dislike this chamber idea. Except from a reloading standpoint.

Re: POF fluted chamber

I would be worried about gas cutting. We try hard to get the brass neck to seal the chamber as quick as possible so any gas cutting is minimized. I am sure that everyone has seen gas cutting
on bolt faces from loose primer pockets or hot loads.

There may be some advantages for the military because they don't reload and if a barrel goes bad they simply replace it.

I don't think "I" want to aid this process. So I will just have to pass on this.

Just My opinion
