That's the laser I sold! It took quite a bit of work to align it. Normal 
trick was to shoot a small hene beam all the way thru the bore, then align 
the front so the reflection of the optic bounces the hene beam back down 
the bore of the hene. Then walk the mirror on the back till you see it 
lase.
