I was hoping someone here could give me a hand. I have read the manual and have taken the MR1 apart and put it back together a few times already. For some reason, sometimes it will go back together nicely and sometimes the barrel/upper will have about an 1/8" gap that will not close between it and the back of the lower receiver. I have the hammer cocked and have tried cycling the bolt rearward. Can anyone explain why it will not go back together sometimes? I should mention that I have ensured that the bolt linkage is in the correct location each time. I'm not too sure what else to try.




























...for me
, the biggest confusion in re-assembly (I had no manual at the time) was in knowing to compress that spring in the buttstock......
