I am working on my last upper....yes number 10 will be my last AR.  I am really considering an ARMS SIR.

I am going to order a RRA A4, CAR length, standard hand guards and etc.  Do I have to remove the barrel to get the SIR on?  From what I know, the delta ring and spring need to be removed and I assume this is done with a Dremel cut off wheel.  

Can you tel me how the SIR mounts? And does it stay tight?

Any help will be great.

Thanks,
