Just some thoughts on that..
You might want to mount the laser on the side of the handguard, or zero differently than the manufacturer recommended.
The sights are an inch and a half or so above the bore, and the laser, for arguments sake, an inch and a half below. If you zero at 25m, for example, with the dot sitting on top of the irons, if you shoot at 100m the dot would be waaaaay high, causing your bullets to impact way low.
I would either mount the laser on the bottom of the handguard and zero so the laser is about an inch and a quarter (or however far below the bore it is) below the point of impact, or mount it on the side, and zero with the dot offset to the same side the same distance it is off of the bore line.
That will keep your laser 'close' at all distances, out to about 250m. That's how the military zeros it's IR lasers and such that are below, beside or otherwise off the bore line.
