Couple of pics here of something I've been working on and working up for a long time. This is two versions of the latest version-- a way to get a carbine-mounted laser with the least possible offset between bore and laser. Both versions shown have it at just over 5/8"..... so if you match POA and POI at, say, 25 yards, the POA/POI dif is never more than 5/8. I'd say 25 yards is not necessarily the max distance the laser could be used at but I doubt it would see too much use beyond that in most conditions.
Gun's gotta have a light on it anyway. Piggybacking the laser seems like a total "why not" to me.
One version pictured is a steel rail made special for this application, pinned and silver-brazed to an existing front sight base. It's more sanitary looking but maybe not the perfect approach due to a variety of reasons.
The other is the aluminum clamp-on version-- I know it's blocky and ugly, but it only weighs 4 OZ, and it's a simple bolt-on. Two pins protruding from the back index it to the FSB.
Since the rail needs to be rather high, and thin, the side walls forming a trough are necessary to maintain a really crash-proof level of strength... I can't stand stuff that has to be babied on a gun like this. Since the walls have to be there, I have put them to use-- both units pictured are drilled for tritium on the back face of the side walls. This gives a really fast "bracket the target and press" sight acquisition, and obviates the need for a front sight post that is too fat so as to be able to accept a tritium insert. I find those pretty hard to use on, say, 300-meter pop-ups.
