Moddoo's triple R5, which Surefire to go for??

[300winmag]

I have no understanding of any Surefire lights but I want to buy one and put a Moddoo triple xpg in it. I searched like crazy but dealing with the search button has me aggravated... again.



I know a 6P has to be bored to fit 18650 so I am curious if there are any lights that don't need modding to fit it and the drop in??

Any favorites? Reasons? Any beginner thread to read for this particular question??

Thanx a bunch
