Got my new 9 mm carbine out of "jail" yesterday and went directly to the range. First shots out of the box were 4 or 5" to the left at 25 yards. (Remington 124 grain FMJ factory ammo; the only box of that I had so it will be S&B or handloads after this.) Got them on center with the rear sight cranked about 1/8" to the right. That's more than I would have expected for a misalignment in the stock bedding. Is anything like this typical?

Groups at 50 yards were fine, by my standards with iron sights, so I guess nothing obviously wrong mechanically with the action/barrel, overall. It's not a meatware problem, pretty sure. I have almost 20 guns and no such problem with any others.

I'm planning to drop it into an HTA bullpup stock immediately (already received that from HTA) so I'll be starting the zeroing process over with a red-dot soon enough...

Adjust the front sight to the left a smidge. Two screws on the underside.

Ah, that would do it. I hadn't even LOOKED at the front sight.

I mean, I looked at it pretty hard while aiming. But not to see if it was moveable.

I've shot an issue Colt M4 carbine that was a foot to the right at 25 yds from mechanical zero. Almost ran out of windage getting it zeroed.

Pup has the right of it. But maybe you don't want to. If you're planning on putting it in an HTA, then zeroing it may really just be kinda a waste of your time.

Geez all these good answers... I was gonna say, aim to the right...

Check to see if the front sight post is loose/canted. 2 of my carbines were like this. Easily fixed.
