Don’t overthink it just do it


This barrel is incredible. Replaced a BA 11.5 on my SBR with this as I was getting inconsistent groups when running my YHM suppressor. I couldn’t find a lot of this before hand so it was a small leap of faith but it’s a Geissele. Groups are incredible, using an Eotech and magnifier I can consistently group at 1” using Federal 55g ammo. I have pushed it out to 350 yards, at this distance hitting a full APSC steel is no challenge for the setup. With or without the can the system rocks, zero has not fluctuated at all in the 6 months I have owned it.
