Most snipers use .36g BB's or above. the gun should initially be chrono'd with a .20 g BB to make sure it pushes under 500FPS with that weight...
Thats not all that true.. I use .29, i have used .36 and .43. The 29's are the best, I only know about 2 ppl who want to use above 29, and thats because they think that the 29's are too much, but its worth it, you get more range and the accuracy is just as good if not better..
I bought the maruzen APS type L96, and got the 500 fps upgrade kit to get it shooting a little hotter but when I finally got to a good chrono, it was going over - like 503, 502 - is this going to prevent me from using it? - I don't wanna drop in 700.00 to not be able to use the thing. - another question - the hop up adjustment manual was in japanese ( big suprise right) - where do I locate a translated version in english?
More than enough ways to take off a couple FPS.. you can cut a coil off.. or add a damper, I got dampers in my rifle... they are so nice. They make it so silent too. If you add a 6.03 inner barrel, it should add alot more FPS though. so watch out.
If you have any more questions, feel free to contact me on aim (far form einstein) or PM me on here

So how good are the new Maruzen Super-Grandmaster .29g bb’s?
For every box of 500, the average deviation in bb size is less than .006mm, with the average bb size at 5.946mm. This is a considerable improvement over the original Grandmaster .29g bb’s which averaged 5.891mm in size and had an average size deviation of .019mm for every 500 shots.
So how do these compare with the Digicon .43g “metal sniper bb’s†that so many are raving about? Well, for every 500 bb’s, there is an average size deviation of .110mm,
which means that the bb’s fall between 5.80mm to 5.910mm in size. Keep in mind that size deviations also result in variations in weight.

Here are some ridiculous statements I see all over the web regarding “sniper†rifles:
1. Why use the expensive Grandmaster .29g bb’s when you can just get 3x as many bb’s with the .30g bb’s? After all, there is only a difference of .01g in weight!
* Well, the weight is not the principle factor here, it’s the overall quality of the bb that makes the difference in shot consistency. The surface and weight deviation of a Maruzen .30g is not very consistent, hence will refelct on how the bb will leave the inner barrel. Deviations among the Super-Grandmaster bb's are less than .006mm compared to .023mm (old version Maruzen .30g) and .055mm (new version Maruzen .30g)
2. Adjustable PDI hop-up units will allow you to use whatever bb weight you want, and it doesn’t affect the accuracy at all.
* At 50 feet, the difference may be marginal, but pull out to ranges past 100 feet, and the difference becomes remarkably different. Not only is the contact point of the bucking to bb too small, but the overall design allows the bucking itself to often fluctuate; resulting in obvious inconsistencies between a given set of shots.
3. Digicon .43g are metal coated “sniper†bb’s
* The “metal†is actually a compressed graphite/zinc composite and was originally designed for being able to knock down the heavier target silhouettes for various close range target comps in Japan. As for being accurate, the Digicon .43g “straight†bb’s are anything but straight. The weight and size variations of each bb are among the worst of all the bb’s manufactured in Japan.
