Alrighty then, So i'm completely new to this forum and relatively new to airsoft sniping and airsoft in general. I usually play a lot of CQB running my 1911 but recently started playing a lot more outdoors and after renting a Well L96 i had to get myself one and thus had my new Cyma 703 thrust upon me for a bargain price. I've played with it a few times and i'm loving it but i think it's time she got some TLC and maybe a few upgrades.

I'm completely new to the whole upgrades airsoft rifles so Hopefully people on this forum can dumb things down and give me some help with getting more range and accuracy with my rifle.

I've been searching for vids and posts for how to upgrade and what to upgrade but alas the internet is not my domain so any advice or help is much appreciated.

Thank you and hope to hear off some of you soon

Honestly......don't get this rifle (though you said you did get this in a bargain price), and if you really need an L96 get a WELL APS2 Type 96 copy.

Assuming the CM703 is a perfect AWS clone.

The problem of the L96 AWS system is that it's pretty annoying to work on. The hop up chamber can't be replaced as there are no chambers for it (afaik, maybe there are but that's beyond me). It's not a problem if you're using the Tokyo Marui genuine version - the quality and accuracy is excellent - but with CYMA's chambers you probably have to be lucky and/or get creative and fix airseals and whatsoever if it's leaky.

The springs are not VSR-, APS2- nor AEG- based - it's completely proprietary but you can get a spring from PSS in case you'll need it.

If the bolt resistance is too much you can get a Zero Trigger kit from PDI or Laylax. CYMA cylinder should be good enough so probably no need to switch to PDI's steel cylinder (not that the PDI is good anyway, it's proprietary in its own way as well).

The major limitation about the AWS system are 1. the cool but prone-to-problems feeding fins which could lead to jams that are difficult to fix, and 2. the small cylinder volume limits how heavy the BBs you can fire over a reasonable distance.

However, what is more relevant to your problem is accuracy, so we'll look at the barrel group and hop up chamber. The barrel group is VSR-based, so no biggie about that, but you will probably have problems in the hop up chamber part.

Thanks for the reply dude, So far im finding that using .25s are the most accurate and .30s get the best mix of range and accuracy but im only getting around 50/60m and I've gotto be lucky with the BB to land the shot. There's a guy i play against using a TM VSR G Spec and he manages to outshoot me at every chance he gets, we played a few games using eachother rifles and the tables were turned, we both agreeed on the issues with my gun and recently i've got in touch with a sniperparts website and they just recommended i buy all their crap because obviously sales lmao but i think im going to use this rifle as it is, keep it clean and just use it for the urban sites i play where shorter range sniping is more effective!

Dolanboi seems to have it sussed but this is something I emailed to someone recently.
The TM L96 does not have a large enough volume for heavy bb's.
Here's why.
A lighter bb does not take much pressure to push it through the barrel. So as soon as the piston moves, the light bb moves too.This means you will have more cylinder volume pushing the bb. So a lighter bb can have a longer barrel otherwise if you have a short barrel the bb will be pushed out to early which means you are not using your cylinder volume to its full potential. A heavy bb needs more pressure to push it out and so if the barrel is to long, there will not be enough air in the cylinder to push it out properly and this will make the bb fly less accurately as there will be a suck back effect within the inner barrel and this will cause turbulence behind the bb. So for you to get the most energy out of your rifle you need to get the perfect match between cylinder to barrel to bb weight.
So the heavier a bb the shorter the barrel it needs ort he lighter the bb the longer the barrel should be.
Here are the correct ratios for each bb weight using a cylinder volume of 20517 mm^3 (TM L96 cylinder volume) : (Barrels of 6.01mm indiameter)
0.32gm bb use a 305mm barrel =2.36:1 (Ratio)
0.36gm bb use a 290mm barrel = 2.49:1 (Ratio)
0.4gm bb use a270mm barrel = 2.68:1 (Ratio)
0.45gm bb use a 230mm Barrel = 3.14:1 (Ratio)

As you can see the heavier the bb the shorter the barrel. The TM L96 has such a small cylinder volume that when you use extra heavy bb's, the barrels become extra short. So a 0.45gm bb needs a short barrel of only 230mm. This will give the bb the most energy possible and the most range. The bad thing is with a short barrel is that there is not much acceleration time for the bb. So really the TML96 is not designed for heavy bb's. It is a real pain. The only way to counteract it is to put in a bigger spring or use lighter bb's with a longer innerbarrel.

So my advise would be to aim to build a rifle that shoots a weight of either 0.32gm or 0.36gm. Or if you do like the L96, sell the one you have and get a WELL MB01 as they have a good cylinder volume.

PS. You may get away with slightly longer barrels but I would not go above 50mm longer than I have recommended for best results.

Im going to second the notion to skip the CM703 and get a type96 replica. You will be much better off getting an MB01 or MB08, same weapon design, except for the magazine location and much more available parts. Ive had an AWS clone and I had a lot of feeding issues with it.
