Usual suspects seem to be OOS. Bonus points for release spring and detent pin.

Thanks for the links. I was looking for a 6951 and the dedicated  “AR-9” releases seem distinct and irrelevant (I should have specified). Looks like MA parts may be the way to go.

FYI, the Colt ones have an unusual shape, I am pretty sure they are being made by DoubleStar.  The finish is also a slick black.

If you are replacing the bolt catch on an older Colt, the CMMG Mk9 bolt catch has the correct profile and finish. I picked up a few as spares from Brownell's.

The answer to this question solely depends on WHAT TYPE of lower you have.

The mag type, and the brand of lower, will go a long way in getting you the best/correct answer.
