I picked up a 14.5" Geissele HBAR CHF for under $300 bucks. While I've had several very good CHF barrels, the only one I have had that came close was in the HK MR223a3 Imports and the sub-$300 Geissele shot better. I'm impressed. I've not been a G$ fan but they've got me paying more attention now.
a quick array of a bunch of flavors including a lovely 0.65MOA 10-round group of IMI in the middle.
That's Fed GMM 69gr in the top left with a 0.9ish MOA 10-round group
Fed GMM 73gr Berger 5-round group top center.
