Hey,

Considering purchasing the M4S-Tactical. Couple of queries though.

First. The battery. I've heard varying accounts regarding the size of battery which will fit in the foregrip. I don't want to have to buy a PEQ as im trying to limit the amount of money im going to be spending. Im happy to rewire parts of the battery area if needs be. I've heard a 9.6v 2000mah will fit with rewiring? Is this true? If not what is the biggest i will fit?
Note: I play in New Zealand and full-auto is illegal here so i will be requiring semi-auto fire only. So a LiPo will see me no benefit in ROF.

Also, The fps limit on our fields is 450fps. What would be the best way of upping my M4 to this? I was thinking either a 9.6v 2000mah batt + tightbore barrel. Or perhaps an M130 spring. What would be the best option? Other ideas more than welcome.

Thanks :)

I use the Intellect 9.6V 1400 mAh nunchuck battery and it fits perfectly with almost no room to spare.  Getting it to fit is tricky at first but once you figure it out its fast and easy.

1600 mAh has been said not to fit because the cells are slightly bigger.

Be sure to get the nunchuck kind, the flat kind won't fit because of the black tabs they use to hold the batteries together.  I tried it.

Check the KWA compatibility list too.

Do you already have the battery? I don't know if it will fit. Possibly if it is nunchuck...

Also, the voltage of a bettery does nothing to it's fps. I would probably reccommend the m130, because you said ROF does not effect you.

But keep it stock so the warrenty doens't wear off.

One last thing, if you mean "rewire", like to a crane stock, the size of the battery a crane stock holds depends on the crane stock.

Interesting. Thanks for the feedback. I'm thinking the 9.6v 1400mah should be ample considering I shall be using semi only. Do you think a backup would still be wise?

If anyone else has any experience with battery sizes etc with the M4 tac i would be grateful to hear it.

Thanks again

Edit: brooklyn468, i meant rewiring so the connector is at the bottom of the hand guard I believe.

If you are going to be using semi only, you might want to get a MOSFET because semi apparently wears out trigger contacts much faster than full auto.  

A quality TB barrel would put you at around 400 fps with your spring broken in.  (I suggest prometheus)  I would much rather have accuracy over power.  A higher fps is going to make your accuracy even worse unless you use .28s (which are costly)  

I suggest you get a TB barrel instead of the M130 if you can only choose one.  From my knowledge, M130s settle at around 400 fps, so with a TB you would get around 420-430 fps, so I think you could make it.  TB barrels usually add 10-20-30 fps.  I haven't heard of higher.  

You would need to break in your spring though, because a new M130 spring and a TB would most likely put you over 450.  So makes sure you break in your spring before you go out and play!

hope this helps

I think he should have enough room for both. I think m130s settle around 410-420, because my m120 settled around 490-495.

The tightbore should add about 20fps or so, and I think he will not need a mofset. A mofset would just be a pain to install, and the trigger post issue only happens to a few people. If it does happen, I think you should get another trigger post, because mofsets give you a higher rate of fire, which you don't need, and because another trigger post is cheaper.

And I really don't see the use for a 9.6v, considering you use semi only. An 8.4v battery would last longer, and is usually cheaper. Also, 1400 mah sounds about right :)

You might want to fix that, M120 settle in at 380-400.  (you put 490  ;))  Second of all, no one said anything about the trigger post.....I was referring to the trigger contacts.  Semi auto burns them out a lot quicker. (I'm not sure why)  MOSFETs not only save your trigger contacts, but they also give you better trigger response time.  (which he would want since he is using semi auto only)  Finally, the 9.6v would also give him better trigger response time.  

And how would an 8.4v last longer than a 9.6v if they have the same MAH?

I agree with you, Im also suggesting a new bucking or nub. If your going into your gearbox you might aswell change your spring guide.

Like Allizard said, your trigger post shouldnt break unless you ahve a lead finger.

Mofsets tend to burn out, too. I hear it is a real pain. I know there are some that don't, but does it really matter in the first place? Mhy would you need a mofset if you only use semi? My KM-4a1 tends to shoot immediatly after I pull the trigger.

Also, I thought the trigger posts tend to break faster on the people who use semi more, who pull the trigger more times in a match than a guy using auto.

The 9.6v shoots faster, draining the battery quicker.

Just my imput  :)

Do I have to say this again........

I'm NOT talking about the TRIGGER POSTs.  MOSFETs don't have anything to do with those to my knowledge.  MOSFETs protect your TRIGGER CONTACTs and prevent them from burning out.  For some reason (I have yet to learn why) semi auto wears them out much quicker.  Since he will be ONLY firing in semi auto due to laws in his country, he will be wearing out his contacts.

As far as your 9.6v comment, I may be wrong, but I highly doubt that the voltage will make the battery drain quicker.  The voltage is just the power and the MAH is the capacity.

Whatever :)

And with the battery, it does. I have had 2 identical mah batterys , 9.6v and 8.4v, and the 8.4v lasted longer.

In my experience a tightbore won't increase velocity by more than about 15fps. I would grab a tightbore and H-nub just as upgrades that I think everyone should do anyway but for velocity I would pick up an M140. It should initially shoot a little under 450fps and would probably settle around 425fps or so. Also as for the battery a LiPo wouldn't hurt because they are very small for the mAh rating and although ROF doesn't matter to you I would imagine trigger response is important. A LiPo allows for a much faster trigger response. Which I find to be very helpful when using semi only.
