I am looking at getting an ARMS SIR #45 or #46. It is the type that has a long top rail extensioin that slides back over the flat-top. I am wondering if ther is enough room to mount a BUIS flip up in the very back on the flat top?

ARMS #40 fits right behind it.

how'bout a CC&G (or GG&C or GG&G or whatever) flip up BUIS?

Don't know, I only have the #40.

i beleive that ARMS made the SIR in a way that only the ARMS#40 would fit on it.

The only sights that will fit behind the SIR is the ARMS #40 or the Knights 300M. The ARMS unit is so good, and at a fair price, I dont see any reason to go with anything else myself.

The thing I like about the GG&G is the way the peeps are set up, two each of two sizes. Plus the low clearence. I don't know why the ArMS 40 would be better? What are its great features besides that it fits behind a SIR?
