But, are those the 'fun' factors?
Not sure it's that silly: Plenty of sites in the USA selling kit. Some LE/Mil forces are going over to laser: Less clearing up (especially vs paintball), less consumables, no 'cheating' (deliberate or not), and far better accuracy at longer ranges. All as far as I gather from 'googling'. I was asking in case anybody had actual experience of a conversion.
