So I have a nice shiny new Colt LE6933 11.5" barrelled Commando waiting for its approved form 4 to arrive back.

In the meantime, I purchased an Ops Inc. Colt SBR collar from one of the board vendors to mount an existing Ops Inc. 16th model once the rifle is released to me.

Question.  Does the SBR locating collar require brazing, welding, etc, as their is no set screw as seen on the 6920 version.

Thanks for any info.

I am also curious. I have an Bushmaster 11.5" barrel on my RR I will eventually do the same thing.

Thanks for the info Bigbore.

Here's a shameless plug for Adco.  THat was the quickest arriving internet order I have ever placed, and I didn't pay for expedited shipping.

Does the Ops brake and collar setup come with the can?
