An xre is a 22 Long rifle and an xml is a 12 guage shotgun ..
I wouldn't try to compare the two ..just buy both ... In the case of this light from meritline ..consider they are lying and are fools . They have no idea what this is and don't care .. it's all about price ..Which means odds are good it's pure crap . they call it a flood to throw zooming light .. They are idiots and the light looks cheap to me . I'd buy something highly reviewed by smart blf members ..Something highly praised by many members ....you just did .. the jacob a60 is a no brainer .. just buy it .No need to try to out wit the members here ..just follow the lead ..As a noob you'll never just stumble into something magnificent . I'd forget Meritline almost everything they have is lame ..Spend the 30$ on the Xintd in a NW or an HD2010
