My 9mm AR wont feed hollowpoints.
It does this about half of the time- https://drive.google.com/open?id=1a3BGEqcvOafxF6w2cEZxJmo-L6BTLZoUpQ

When a round jams, it pushes the bullet back into the case. It runs 98% with round nose bullets. I have used glock factory mags and ETS mags and they both perform the same.

Matrix Complete 8.5 inch side charging upper
Matrix lower
Kak blade with Kak 9mm buffer

Brass is ejecting at about 2 o'clock.

Any help is greatly appreciated!

Which hollow points have you tried? I was wondering if it would feed Hornady Flex Lock bullets.

They are freedom munitions 115gr with new brass.

How are the feed ramps on these?

Are you using a standard carbine spring?

could it be the feed cone on the barrel? are they all pretty much standard on 9mm barrels?

I fixed yours in the quote to make them a link that works.

Sorry for the delay in reply....was in the hospital for some tests..........all is well.......

From the pictures I'm pretty confident you would benefit from having the feed cone corrected, shoot me an email.... [email protected] , Just to confirm it Is an 8.5 inch barrel.
