Buffer weights, bolts and ammo. How do they play well together?

Sorry. I missed that. Not paying attention.

Yeah, but perhaps i'll try a few different weights with the idea of needing more blow back to eject?

Idea of what to try? The pics of two different barrels looks the same. But that's my uneducated eye.

Try hand cycling a fired case or dummy round.

The ejector should push the case out of the ejection port.

Great idea. Thx!

Ejector could be bent or broken, causing failures to eject. May not be bolt speed issue at all.

Just to focus you on what matters, the muzzle break has nothing to do with it. Browning actioned pistols need the spring containing Neilson device for proper function. An AR does not because the barrel does not move in the receiver.

Yeah, gotcha. I really like milspec and then I hate it.

Mil-spec, by definition of the group that hold the qualifications, the military, is the lowest quality of acceptable gear. Anyone on the Mil-Spec March is claiming loudly they can make do with the least.
I can, but I don’t. I like things that are better than the least acceptable product. I like stronger, smoother, lighter, more durable, easier to clean and prettier, than the lowest thing that will work.

Paying the least one can for mil-spec is a different foot race, that can also be fun.

I feel like the ejector/extractor is the issue. Or the Spikes upper. I know they look cool and have fans, they also have a Kimber reputation with me. Pretty parts though.


A good test.

At any speed. If they extractor looses it early, it just flies forward, when the bolts comes back home, it crashes it into the other case.
An AR held upright should have the case clear the port at the slowest hand cycling. Things don’t get better with speed, just more forceful.

They’re super fun, but I don’t own a PCC. Is the Spikes Lower ejector in the lower receiver? Could it be too short and making contact too late in the cycle?
I know you will get it figured. That’s a nice setup!

The bolts work with a longer barrel or no muzzle device. Thanks for the thoughts. Any direction or idea is greatly appreciated.

Thanks for the thoughts. If I pull everything off the end of the muzzle, it works.

Hmm. More curious yet. If the ammunition is just on the edge of function, I suppose a muzzle brake could sap the little bit of impetus needed to have the bolt work right.
Of course, if it’s screwed into a suppressor, there is more than enough back pressure to operate it. Could your setup be for suppressed only use?
Do you have a suppressor?
What is your ammunition?

I’m baffled why it would work with out a muzzle brake. It is supposed to be blow-back, not recoil, operated.
