I just installed my Waffen Burk MR223 11" AGB on my 10.4" upper today. I haven't shot it yet but the roll pins supplied were indeed longer. I froze them and still could not get them fully in, going to have to press them in the rest of the way.

I remember from the waffen burke gas block thread, a 1.6mm gas port would make full use of the range of adjustments on the gas block. Tho burke himself said it wasn't necessary?

Oil, hammer, roll pin starter, and roll pin punch did not work to install them? Sounds like my experience with with roll pins for the safety selectors.
They are about $6 each and I used nearly ten of them on my first selector set. The still bend and bind and I have yet to understand why.
The selector roll pins were the absolute worst. I could only ever get them about 80% of the way until they started blowing out or bending on me. I gave up and just cut the excess off with a pair of dikes.
@zinny I emailed Mr. Burk and asked if my AF datecoded barrel required enlarging the gas port to 1.6mm and he said it was not necessary. All my silencers are in NFA jail so I won't be able to test all the settings for awhile.
