AR-15 Ejection Pattern problems/ Overgassed

[4g64loser]

I am assuming you need to remove the sight tower in order to measure the gas port correct?

Yes. And own plug gauges.

sounds like a GB is gonna be his best answer.

...which was suggested hours ago. I warned against set screw GBs. They are basically a once and done adjustable GB(not to say they can't be readjusted). They are fine for an AR with an over-sized gas port. But, if you will eventually add a suppressor to the mix, you will want a "field" adjustable block with click adjustments that will allow you to dial in your gas so, ultimately, your gun will function, both suppressed and un-suppressed. Trust me, that is a better way to go.

I have no Gauges, I think the best thing is just install a AGB. Does PSA build their rifles overgassed or is this just a mistake you think?

AR15s as well as all semi-auto gas guns are made intentionally over gassed to keep them running when they are over fouled. They are made to run dirty and dry(never run your gun dry, though).

If you have a selection of small drill bits they can be used as plug gauges. Just use the side that would be chucked in a drill.

I believe most manufacturers over size their ports as a way of making a rifle work with a wide variety of ammo.

Most fighting guns are seriously overgassed for reliability.

Sometimes you get one that's just beyond nuts. My most recent Daniel defense was not that bad but it needed to be toned down. The barrel replacement alone would have sufficed but it's a game gun and I wanted it to shoot "dead" for faster follow ups and better spotting. I can run it easily from a barricade with a relatively easy grip and watch the impacts in my 1-8.

Dry docking is bad.

If the gun runs, who cares? Shoot it.

Roger that, I have researched gas blocks in the past and never could decide on the SLR vs the SA?

Over-gassed is not the end of the world and better than under-gassed. That being said, the adjustable gas block is one option (and a good one). I will offer up another option; a tuned gas tube. Just pick the size (carbine, mid, etc.) and fill in the form and they will pick the hole diameter. I have a Colt with an 11.5" barrel I run with a can. It threw the brass at 12:30 into the grass. Replaced the stock gas tube with a tuned one and it is perfect.

my wife claims that also? I had to say it.

 

[clandestine]

It's not really, other than being a Wilson Combat chrome BCG. Wilson just calls it enhanced.

I see a ton of issues from WC AR's and components.

Better listen to her.

I assumed Daniel defense did too.

And clandestine would know. He's a recognized expert on the platform. Google school of the American rifle if you want to see his resume.

There is a standard port size, so yes for the most part. Black River Tactical makes custom gas tubes to order.

Lol!

Same here on a much more limited experience.
