Which Bolt 6.5 Grendel

[A5BLASTER]

It is the one for the 550 , if I'm recollecting correctly. If you look in the Q&A section it explains it. It was a game changer for me.~Riuma

Addendum: Just checked. I'd sent an email to Timney and they had responded that the 550 trigger is for the 527. So order the 550 trigger. Expect ta daub of epoxy in the sear engagement screw. It pops right out.~R

After adjusting the trigger in my cz grendel varmint I couldn't live with a timney.

Love me some timney triggers in my remmy's but non of them compare to my cz trigger now that I got it adjusted.

But with all things gun feel is subjective to the user.
