POF P-415 not ejecting properly, high recoil

[The_War_Wagon]

It's like it is unlocking late. My impression but guessing.

It's a piston. It WILL unlock later than a DI rifle. An H3 buffer will add another microsecond or two to that as well.

Called POF today, they seemed interested in the issue and confused in the situation. Here's to hoping that was honest and they will get back to me with a solution.

I may have to invest in a spring and H3.

Thanks all.

Called POF again yesterday, I never heard back. Explained the situation, again. Put me on hold, came back with "talked to ..." and "said try replacing the buffer spring, they can relax". Huh, really. That's how springs work?? I told him I did, also tried an H2 buffer with no improvement.

Put me on hold again.

Came back and asked me to photograph the part of piston system to confirm parts in gun.

I'll follow up this morning.

I’ve got 3k+ through a 9.25 gen 2. Sold upper, but I have some time on the gun.

How does it run in S mode with XM193BK?

Also, for the hell of it have you removed the “rail” to expose the standard upper below?

[NIXDSG]

In "S" mode 5.56 and .223 both work better, ejecting at 5:00. The 223 worked flawless during 700 rounds hunting, but first 5.56 failed to eject, then seemed to work. Again, this was in "S" mode.

In "N" mode both are ejecting at 1:00 and recoil is high. Multiple fte.

I tried H2 in "N" mode, didn't change anything. I don't remember using g H2 in "S" mode, might improve 5.56.

Not removed rail, how would that help?

Not sure it would other than ensuring its’ put together right.

Apples / oranges but mine ran fine with fed223&xm193 in N, carbine spring, un-suppressed H2 or suppressed H3.

One of the most reliable ARs I’ve ever owned. Although a lot of gas to face suppressed

Hope POF steps up. Stay on them

Have you checked the rod to see if it was binding on anything?

[NIXDSG]

Have you checked the rod to see if it was binding on anything?

Yup. Moves free as can be.

Not getting a response from POF I had given up on their support to resolve this, but yesterday they called me back! No solution, just asking for info and pictures that I'd already sent them, but that's ok as I'm happy to resend.

So, they are still working on a response, I'll take that.

In the meantime I've cleaned/inspected everything, again. Also, I purchased a blue buffer spring and H3 buffer. Pending testing.
