Brass ejecting towards the muzzle
5/8/2012 12:04:36 AM
On my 6.8 16" mid length upper the shells eject towards the muzzle of the gun. I currently have it on a military spec stag collapsible stock. Do I need to change my buffer or spring? Thanks.

Your rig may be over-gassed.
Some will say, it's working...leave it alone.
Several ways to slow it down. Buffer, spring, adj. gas block...

Interesting chart. I just installed a Centurion rail onto my carbine. I replaced the gas tube with a new one during the install, and the ejection went from 4:00 to 2:00. I wondered why, but it makes sense now. I guess that more gas is flowing though the new gas tube.

The chart really doesn't mean much.
Most of the time a rifle appears to be ejecting forward, its the brass bouncing off of the shell deflector.
If your rifle feeds and fires w/o malfunctions, I wouldn't go chasing down clock patterns.
Just changing ammunition will have a bigger effect on recoil and shell ejection.

I have a similar situation with a 6.8 upper. It's been that way for 500+ rounds and I''m perfectly comfortable with allowing to to continue for another 500. It's not creating an issue and I'm not the type to pick the fly shit out of the pepper.

mine are both carbine length, they were so overgassed the cartridge rims were actually bent out enough to be noticeable when stood on end on a table. PRI adjustable gas tubes solved it for me. Shooting 110 grn pro hunters from Silver State( NOT tac loads)
