NcStar Compact Red Laser Sight with Picatinny Mount Interface
[CN/AAPRLS]

This laser is very compact at only a couple of inches in length which is great but do not expect a super bright output. It's more than adequate for indoor ranges and I can clearly see it at 25 yards indoors. If you take it outside and it's bright it gets a bit washed out and hard to see. With that said this is probably be the case with any compact red laser sight. If you need better visibility I would pony up the money and get a green a laser which is easier to see in day light
