So I made a mod for Fallout 3, back before Fallout: New Vegas was released:

I made it to address the distinct lack of semi-auto rifles in Fallout 3, a problem which New Vegas does not have. The actual function of this rifle is well-served by the Service rifle - a 5.56mm semi-auto rifle. Is it worth porting this weapon to Fallout: New Vegas anyway?

Dude, if you want to port it, port it. You should mod for yourself not for others.

Also your old one got 86 DLs which is good but means that you won't neccessarily have a host of loyal mod fans begging you to port it..

Yes, more stuff on the Nexus is always a good thing, especially in terms of equipment. If you want to port it, do so.

What he said.

By the way I think your gun looks pretty cool. I'll get it when you port it.

and yes, change it to be compatible with true sights.
