Buffer tube ? on an SBR with SIG Brace

[gingib]

I have a new .300 BLK SBR with 10.5 inch barrel with a SIG Brace and am looking at adding an aftermarket KAK or Phase 5 buffer tube. I have done a lot of research and watching videos.

I am looking at adding one of these buffer tubes to add 1-2 inches of total length as I have long arms. I watched videos and saw where if you take off the SIG brace from a stock buffer tube and add to another buffer tube it will be too lose and spin around and not stay in place.

Is this true?

Anyone have any history with adding a new buffer tube to an already installed SIG brace?

I had the phase 5 and didn't have any issues, have since got my stamp and it's SBR now
