You can hit something accurately at 60 to 75 feet?

I mean, is the gun accurate enough that having a scope does any good. For a uniform projectile, even a smoothbore gun should be able to hit inside the circle of vision provided by the scope, with proper calibration.

With a reliable and repetative valve, firing say 5 times, are the crosshairs any good? Or are the hits all over inside the field of vision? Or is it more blind luck and wishing you could hit what is in the FOV?

nice accuracy. I suggest you to try using steel pipes and fittings next time. u can use much higher pressure and smaller chamber with better performance.

Do u use hop-up for firing marbles ??

Oi!! thats not the best way to comment on someones creation.


i don't mid this gun, perhaps just take the bottle off completely and have a smaller chamber. just put the fill point in an end cap or something.

In an attempt to either confirm or debunk this unproven claim I sourced photos of both a bottle and some crap.
The requirement was to get a reliable opinion on whether the two were alike.

Step 1: I entered town and asked 100 passers by. They either refused to answer(37), or disagreed with the proposed theory (63).

Step 2: I contacted a police officer I know, who fed the images through a very advanced machine that is used for finding the likelihood of two images being of the same person.

The results were negative, but this may be a result of the machine being used for a purpose outside it's normal parameters. Recalibrating the machine would have taken many hours, and affected the readings for other users, so this line of enquiry was exhausted.

Step 3: As proven by Google's highly successful and patented Pigeon Ranking system, pigeons have a high ability to recognise when two items are related. We sourced 100 pigeons, and set up a balanced test where approximately 6 items were arranged around and the pigeon was required to select the closest match to an original.
As a control, some tests featured neither item in question, and these were used to calibrate for each individual pigeon.

Of the 1000 tests, 659 featured one of the two items, 482 both. Of these 482, there were 2 tests that received match results, but it was later discovered the pigeon that had performed them was really a salt water crocodile, so we discarded those results.

None of three tests would confirm that bottles and crap do look alike, so I would propose this unreferenced statement is removed from the article in question.


On a far more serious note, nivekatoz, you have many suggestions; some like this, useless and outright rude; some pushy; some promoting websites incessantly. I mentioned it elsewhere, but if you don't clean up your act, you're going to get dropped on by the mods (and regulars) like a tonne of bricks.

Now, watch as I express a viewpoint:

I don't particularly like the bottle you've used. The launcher would look much better if you could replace it with a rated PVC chamber. I know you have already said you like the bottle, but PVC would be safer, and allow you to use higher pressures without worrying.
Shortening the vertical gap between the chamber and the barrel would also help appearance.


Like you, I said I didn't like the appearance of the bottle. However, I didn't directly insult it, and - this is important - I made a suggestion for a replacement. I also showed I had registered previous posts, and expanded on another aspect I'm not keen on.
That is a reasonable post - polite, helpful and informative.

1. Keep the flaming to a minimum. Remember, you were a noob once too. Also, keep in mind that this is a text-based medium, and as such, sarcasm does not always translate well.


This is the second time you've posted such a phrase. You might want to tone it down just a bit before the Mods / Admin "have a talk with you."

Don't take that to heart. That was unwelcome criticism. There are a lot of launchers that use a bottle for the chamber that look quite nice. Besides, how many other negative reviews has this launcher received?

Time out. Take a deep breath. Now exhale.

First off, no one has every recommend that you stop trying to help people. That is what this forum is all about. Next time when you type a comment, read over it. If it is something you feel may be controversial, don't say it.

Yes I hate e-mails too.
But I don't believe that you could have added any tone to your comment that would have changed its impression.
