If I get a 11.5 barrel can I use a 9.0 rail on it or does the M4-S extend back too far?

Also, do you guys still offer the 11.5's with custom gas port set up for the M4-S?

Yes, will fit, but needs custom collar.

Sorry, we do not offer the custom 11.5" any longer.

I'm sure they can make you one, just not for the same price...

Is the custom collar something I could install myself? I am my department armorer so I know a little bit lol.

depends on the barrel. If you just need a slip over collar, yes.

If you need a slip over collar, but the barrel needs to be contoured to hold it, there is the issue.

Will a BCM barrel need the contour?

I would need to see the barrel.

Will the collar go right on the Daniel Defense CHF 11.5 barrel you have in stock without modification? And do you know if the M4-S will fit inside the new Troy Alpha 11.0 tube?

We will supply a collar for the DD 11.5" barrel.
The OD of the can is 1.5', what is the ID of the rail?

The Alfa rail has an ID of about 1.4", so no, the OPS cans will not fit under.

OPS cans WILL fit under the Spike's BAR rails.

Ok. How do I order the barrel, collar, brake, and a low profile gas block with dimples on both set screws?

order the parts on-line, and put the specifics of what you want done in the comment section.
