The 1-7" twist will work well for subsonic and supersonic loadings alike and there is typically no need for an adjustable gas block when switching back and forth between the two loadings.Wilson Combat SBR Tactical Profile BarrelsTuned for outstanding reliability, the Wilson Combat SBR (Short Barreled Rifle) Tactical is our smallest Custom High Performance AR rifle barrel.
