To summarize.....
Don't utilize bolt catch(last round hold open). Use the right bolt/buffer Possibly use ss pins or kns pins. You should be fine |

But to answer your question, yes, the 9mm blowback operation puts more stress on the lower. Specifically on the hammer and trigger pins.

Go with a heavy weight buffer to minimize stress. I love the KAK 10oz buffer.

My understanding is it has to do if the bolt carrier is "ramped" or not.
I have a OLY system on a RR16 and it works great. Never have and any issues (and I do not use KNS pins). LOVE the ability to just switch upper and I'm back to 556. |
