Has anyone gotten their hands on the new SIONICS 18 inch barrel? Looking at barrels for an SPR-ish build and wanted to get relative accuracy info vs BCM/Centurion/etc...
Just ordered a 11.5 RGP and upper to go with a MK3 10' I had stashed from a sale and looking to build a set of uppers SBR/SPR for range days.
