AR15 throwing brass forward

[Trinimon]

Love the 3BUCC. I recall when they used to be $24 for the extra mount. I shudda stocked up on a few more back then.

What buffer is OP running? Also is it a 16 inch barrel with a carbine gas system?

The easiest fix is changing the buffer to a H2 buffer or heavier. Honesty its not a huge problem, its definitely not dangerous

I like the brass catcher ideas.

As others have said, forward ejection is caused by over gassing. Is this an issue? Maybe. The issue with over gassing is that it has the potential to be hard on your gun. The main issue that overgassing will cause sending your bcg into the lower receiver (bolt bounce) , damaging the lower where the receiver extension threads into the lower and also damaging the gas key. If this is not happening then I would not be too concerned. When I see undergassing and short stroking that is were I become concerned.
