I decided to take my Saturday afternoon to install some 922r parts and ran into a significant problem.
I bought this US HK93 pattern extended cocking handle
as a way to help make my Z43P 922r compliant when my form 1 comes back. I haven't found any other information online about installing these as a 922r part so I guess I am the guinea pig on this one. The one above/ on the left is the US HK33 handle, while the other one is the factory MKE one.
Anyway, I installed the new charging handle to see if it would work despite the different geometry but it would not fully close. I'm not sure exactly why but I did not force it.
In addition to the cocking handle being designed differently, the cocking tube support also looks pretty different from standard. This makes me think that if I were to get an actual HK33 cocking tube support that this would work correctly. However I dont know enough about how these things work to want to spend $100 on a guess.
Does anyone have any insight or have any experience with this? I would love to not have to swap out my bolt carrier for a US made part just to be able to use a A3 stock.
