CAT Old Dirty Bastard HUB 1.65

CAT Mobster 9 HUB 1.65

CAT White Bread 1.55

CAT Dirty Dave I have written down as 1.65 but I couldn't find where I sourced that from so it could be different. Thought I remember CAT saying the DD had the same depth as the ODB.

B&T Print-XH - 1.6" of space from the start of the threads to the beginning of the blast baffle. For both the full size and SC version.

EDIT: Oops, already listed above.

Great idea for a thread. I have a few I will try and measure soon. CAT sent me the below when I inquired about the JL.

Any idea about the blast baffle distance of the Sig Hexium 556?

@aftac

A little late, maybe you found the info.  I recently purchased the Hexium 300 for my 300 BLK.  It is very short in the throat.  Per the manual from Sig that I downloaded, the Hexium 7.62 and 5.56 show a distance of 1.45 inches for those models.  My 300 shows 1.25 inches in the manual, I it is definitely that.  So I suspect the manual is probably correct for the 7.62 and 5.56.

I just found this today.  I need I have a PWS Pub mount on it but it looks like I need an XL for the Sig.
