Is anyone using the G super 42 spring and buffer? What weight is good suppressed/unsuppressed mix? Sorry if I've missed this somewhere. Is the 42 spring "correct"? |

Could someone post a photo of their feedramps? I am experiencing issues when loading on an empty changer - the first cartridge gets hung up midway out of the magazine. Usually tapping the bottom of the mag closes the bold. After looking at a rifle, I noticed my feedramps looked as follows (not the pockmarking on the left feedramp):

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.

Looks like I was wrong - after another cleaning/chamber brush, the pockmarking looking area is gone - it was probably caked on carbon.
Here is a better photo: However, it still leaves the question: what could cause the issue of loading on an empty bolt using bolt release? This hasn't happened on any other AR (BCM, Colt, with the same lower). 
Here is the rifle as configured:

@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 |

@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. |

Another Geissele curiosity, this is Barry Dueck from Surefire, in the video he shows a carbine with a 11.5'' barrel, specifically calling it out, but please note that the MK16 rail has 5 slots instead of 4 MLOK slots on the side, and it appears to be a bit longer to mate up better with the barrel. @MNRidesHonda mentioned this earlier in the thread, but I believe it may have went unnoticed.
I wonder if Uncle Bill will allow us to buy these?

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? |

If you look at the front of the rail in the picture, it doesn't have the larger area without picatinny slots or the ramp that's normally there. This makes me think it was a one-off or custom chop. 
The barrel in that SF video though is a bit longer than on the test mule that I saw. Edit to add: I’d stock up on Colt 11.5” barrels; just saying haha. |
