PM me if these get down to $100

Is that a tripod mount I see? If so, sweet!!

Me too

8/10, did a little better on this one...

Man, the orange is awesome. Great pics!

It does clip the beam but is cheaper and mainly easier. That being said, the splash is pretty bad also Just thinking it's a practical option for the op's use

Most of these import cheap lasers are often full of epoxy anyway, just a waste of time

I use a 3 element lens in my 44 build for better beam quality at the cost of a small amount of power

Geezzzz......5 of ten...:LOL...

Surely not as delicate as the single mode?

Awesome bit of homework Hak, May be in for one Danny
