Any NX8s in use on these things?

Thank you for the photo. I tried different magazines (USGI) and even put in a new action spring with the same results. My concern is the pockmarking visible just below feedramp - I don't see anything like that on any other upper I have.

Are the little rounded white spots on the receiver right before the extention indentations in the receiver or is it light
|
|
|
Are there any marks on the gas key were it could be hitting the gas tube , can you feel any burrs on the feed ramps
|
|
|
Couldn't feel any burrs on the ramps. Will look into gaskey / tube more tomorrow.

@jdoc69
What ammo are you using? Just had a standard M4A1 that didn't want to feed Mk262 off the right ramp. Seems the receiver M4 feed ramp on the right side got a burr/gouge. So, the BTHP nose was hanging up on that side when fired out of USGI mags. No issue with MPags or ball ammo. Solution was new receiver and barrel. Gun goes out the wire so needed it to be 100% with any combination. CD |

This hasn't happened on any other AR (BCM, Colt, with the same lower). https://i.imgur.com/9lCFIht.jpg?1 Here is the rifle as configured: https://i.imgur.com/uCKSHx7.jpg?1 View Quote |

@combatdiver:
I think this is happening with ball ammo (don't recall the actual brand, not match HP). I did examine feed ramps both in the upper receiver and barrel extension and they appear to be smooth. |

View Quote just curious, have you tried PMAGS? although, yes, it should work flawlessly with USGI metal mags. are they new USGI mags? my theory is that the sharp metal mag feed lips are holding on to the cartridge to tightly, whereas a polymer mag feed lip will allow the cartridge to tip up as it gets levered up the feedramp. just curious. |

Looks like the MAWL just got adopted by the DOD.
Any idea how that will work with the URGI issues and if the units using them will be getting the MAWL? |
|
|
Are the 10.3" URGI's going away? I saw that Brownells' had them as discontinued.

My 14.5 URG-I came in today. Are these running well suppressed and non suppressed with H2 buffers? I have a couple golden tickets to burn on surefire lights...open to suggestions.
