350fps

Recommended Posts

I've got a classic army aug a1 on the way which I bought from a forum, it's set up too run 11.1 lipo for high rof.

 

It's running 300fps on an m90 spring and stock barrel,

 

I was gonna order a madbull 6.03 TBB and SHS m100 spring now, but I'm thinking that's gonna take me above 350?

 

Out of the 2 what would you buy/try first? What's the most effective?

 

Cheers

personally the madbull, because it should increase accuracy as well, whereas the spring will just increase FPS.

It's a guess, but I think the TBB is only going to increase your FPS a bit. Maybe 5-10 FPS. You're getting ~ 30 from the M100 spring. Agreed with Flex though, barrel is better because you get the accuracy.

the m100 shouldnt put it over 350 but if it does then it will only be by a few fps which most sites wouldnt worry about.

It could do quite easily of your air seal is good AND you fit a TBB. I know mine did.

And spend a bit more money on the barrel if you are gonna do that, madbull aren't the greatest by a long chalk

 

Prometheus is the way forward

Might sound daft this, I understand you pay for what you get ect...

 

But what sort of difference is there between madbull and prometheus?

Both will be fine, you hitting 300fps on a m90 - kinda expected stuff

if you was getting say 310+ on it then your seals n $hit are way above average

so average good condition is on par with what you have atm

my guess is around 345 aprox but so many variables but reckon just under 350fps

if you get over 350 then I will eat my words

 

You will never know until you try it - spring cost is minimal though

if you was really paranoid then a m95 - but wouldn't be worth it

 

buy both - fitt tbb and if you are @ 315 you should be fine to use m100 spring

or wait a while until she drops to 310 to fit spring or next gearbox overhaul

 

blah blah blah

I've not received the gun yet, but it's stated 300fps, ill chrono it when I get it and go from there.

Be aware of dodgy chronos, I know for a fact my M4 has an average muzzle velocity of 310-320 FPS and one at my local tried to tell me it was firing at 270 literally 5min after using a mate's machine. They can be pretty inconsistent.

I use my dads chrono which he uses to chrono his rifles,

 

To be fair it's only 3-4 fps different to my local skirmish which is handy.

I got x3200 genuine and it seems to be matching my sites chrono bang on

(mind you they did used to use same chrono)

 

at weekend though I noticed a different one and reckon it was quoting a bit higher fps

gun I was using was no way so close to 350 - 347 to 348

reckon it was about 339ish - hmm forgot to check that on mine

 

new batteries & all that in ya chrono they say if you get weird figures

 

my one can be a right fussy fvcker - if gun is not 101% straight or in centre I get TOUT

the site one went nuts, fired at full auto then flicked at first switch back n forth & she went

back to single shot - but 555 or something daft showed on chrono when auto ????

yeah right - so think that chrono might be a little suspect in my book

 

Alas site chrono & marshal's word is final they say, but they are only a guide.

some sites often allow a little over but not all, still I will keep an eye on readings at home &

at site if they start to say my gun is too hot
