Vortex Flash Hider POI Shift? Group increase?

[cosermann]

Has anyone experienced the installation of a Vortex Flash Hider (G6A2, G6A3, or G6A4) either shifting the point of impact, OR increasing the group size significantly? Saw it mentioned online that it was "notorious" for this, but have not seen it myself.

No, I have several builds with them.

Thanks. I haven't observed it either. I read that and I was like, "wait, what?"

I just zero'd this Sunday. No issues. I was 2.75" or under from bench with Frontier (Hornady IIRC, the brown box stuff) 55 grains (1:9 twist, Faxon barrel).

(I put an index card on a B-27 so I don't lose the dot placement, harder to shoot groups with a dot, lol).

Not to hijack my own thread, but how do you like that Romeo7?

I am big fan of SIG optics. Love the Romeo7. Can take a beating, takes AAs, nice big field of view, QD mount that can co-witness.

Note: I do not have night vision. Night stuff EOTech is still king.
I am considering that PA 3X microprism on the Katana 3.0/WWSD to kept weight down. Sunday I had the Romeo5 on it and then a Green Dot and Juliet 3 on the RRA PDS, I am trading back and forth on all my C guns.

Anytime you add weight to the end of a barrel, you run the risk of POI moving, group size shrinking or enlarge........ever see guys add a tuner to the end of there barrel? Moves weight back and forth to improve group size

Remember the Browning BOSS system?
