I'm trying to get some good info before I invest in the ARMS SIR system. If anyone can provide some details it would be great.

What's the difference between mounting the Military vs Civilian?

Is one more bulky than the other? According to ARMS, there is a difference of 1 oz.

Are they stable?

If I am missing an important point, feel free to bring it up. I just purchased my first AR15, therefore I have limited info.

Difference between the M and C models is that the M model requires removal of the delta ring assembly (either take your barrel off or else just use a Dremel to cut it off). Otherwise, they are pretty much the same thing.

For what it's worth, I got the C and now wish I had purchased the M, primarily for aesthetic reasons. I'll never need the delta ring again so I should have just dremeled it off.
