Did you just break the bank buying your dream gun but have no dough for optics? Never fear! Leapers will save the day!

For about $30, you get a decent red dot that will get the job done w/o the bells and whistles. I use it on my Remington 11-87 and it still shoots 3" slugs accurately after approximately 150 of very punishing rounds. I got a second red dot for an AK-74 and the scope is more accuarate then the rifle.

This is a great scope if you plan on messing around at the range but I wouldn't put it to the test if you plan on hiking/hunting with it for days on end. The green dot option has been lost on me so far but I guess it's usefull if your being "tacti-cool" at night or something.

My only problem so far is the pin to one of the flip-up lens cover worked its way out and I used a picture frame nail to replace it. Otherwise, bang for the buck, you can't beat it. 4 stars

I got this for my paintball gun. It is made of metal, is built pretty well, and overall feels very solid. Sure the flip up lens covers could be more durable, and the dot more crisp, but that's OK. Choice of color and brightness is very nice. My main complaint is this. The dot moves with relation to the position of your eyeballs. So for example you fix the gun in place, with the dot on target. As you move your head around, the dot will move around off target, even if the gun has not moved. This means you must be very consistent with how you look through the sight for it to remain accurate. Even then, it will always be somewhat off because you can never look through it EXACTLY the same every time.

For paintball, this is plenty accurate. plinking at short ranges, ok. But if you need serious accuracy or consistency (real hunting vs. varmint shooting)... keep moving. If you need a good low cost site for a pellet gun, BB gun, paintball gun, or .22... You will probably be pleased. 4 stars

I used this for paintball on my military simulation A-5. I see other sights and I was worry about this since its cheaper. The red and green dot is MUCH more visible then my brother in law more expensive BSA also.
About the manufacture website, it is a 40mm. Dont know why they said 30mm. But like some sight, the lens (both front and back) are both 40mm but theres a inner tube that control the up/down/left/right of the laser and it decrease the viewable area just slightly. Overall, it worked great. I can tease/tuant my teammates with pinpoint shots near them. 5 stars

good lens. Is a little bigger for my paintball marker (tippmann a-5) because I cant put it right with the loader. The 2 lens covers are too big, so if u wanna open and close them u will have problems with the space. Also, it comes with special adjusters to fit in the marker's rail, BUT it has (I dont know why) 2 diferent screws to fit it, the front one is lower that the rear one, so I couldnt make it fit lined up. Be carefull if you want this for a paintball marker. 4 stars

I got this scope when i ordered my JG G36C V3 airsoft gun. It works perfectly with it. Easy to put on. Easy to adjust to hight and wind. Green dot works good when i'm fighting inside dim houses and red dot works great outside. %100 recommend it to anyone who wants more accurate shots for an airsoft gun and not break balls with the price. 5 stars
