Hello I need a little help here, I have all my components for my 10.5" pistol build - its all Noveske - 10.5" 300 Blackout barrel.  I am putting an SB Tactical SBPDW pistol brace on it, what spring and buffer weight should I use?? I will be shooting mostly supersonic and will eventually have a suppressor for it.  Ive read everything from JP silent capture, Wolf XP spring, spikes t2 tungsten buffer??? obviously, I really want it to work with both super and subsonic rounds but it seems a very fine line for what spring/weight combo works??...

I really appreciate any help, thoughts and info!

Not sure what dia. gas port you have but I am running standard spring with H2 buffer in 3 different barrels with no issues at all.  .093" gas port on 8" and 8.3", .082" port on 10.3". I think that combination is a good place to start. You could check with Noveske and see what they recommend.

Thank you for the reply! I am going to try it,  I just heard back from Noveske, they also said to run the standard carbine spring and H2 buffer.  I really appreciate your time and reply!
