hey axis, why do you want to upgrade your spring to pdi 170%. I know its a cheap way to upgrade when you want more fps, but in the long run your mechbox and internals are just going to suffer big time(if use full auto alot), and also your rate of fire will drop. If you want to increase your fps and keep your rate of fire, id suggest to upgrade either your, cylinder, cylidner head, nozzle, hop up bucking, and or piston head. I hear even getting a tightbore barrel would help in fps. Speaking of tightbore, i just ordered a madbull tightbore and im anxious to see how much of an improvement it will do.

P.S. : www.airsoftmechanics.com is an awesome website with tons of info on airsoft. The forum is also amazing with lots of great info.

You do full auto a lot, axis so you may want to follow his advice. Also, I bought a prometheus tightbore for my M4 S-System a while back and it put me at 415 fps using an m120 spring so just that barrel gave me about a 20 fps improvement.

i already got the spring and i sent it to them for the upgrade so it 's kinda late for that but i was also planning to shoot smarter seeing as how .25's are slighly more expensive than .2 bb's i was also gonna swap out my turbo 3000 from my mp5 and pout iot in the m4 or buy that systema motor that is in the classifieds, but i will definetly put more time (and money into my gun)

edit:this may seem kinda dumb but i don't know what i want to upgrade first inernals externals or both at the same time, who has suggestions as to upgrading to an affordable/prctical level

In my opinion, externals are not nearly as practical in airsoft as internals. It's like power vs. poinless haha. New sights or a scope is one of the only things you should need to upgrade, if that.

I think you should wait until you use the gun a little. Then see what you think it needs.

i've already shot a good 800-900 rnds (3 hicaps and 1 100rnd) so i have a fairly good idea of its range and accuracy(my backyard is about 90-95 feet across and i can hit a milk carton sized target consistently) i'm considering a tightbore,still, and maybe even that motor in the classifieds (or maybe a new one off evike).

i'm also looking at a guarder acog and a madbull halo silencerand some type of vertical grip

I thought you were on a budget. That sounds like one hell of a grocery list. Like sureshot said, try you're gun at a game before you decide; backyard targets are nothing like picking out players in the field especially when they are firing back at you

Im not usually one to quote the quotes, but like I said before and like Adam said, backyard targets dont mean anything, and i think you need to try it out. And where are you getting this money?

Not to be mean, but with your luck, you will get all of this stuff, and your gun will blow up.

first of all guns implode ...that's just common knowledge... lol

i got some money saved up... and my birthday isn't untill june so i'll have plenty of time/and money to see what i want and need, plus it's not that bad when you put it all together (it's about 180-210 from evike including a tightbore barrel)

Ever think that your also almost 16 and may need a car and driving school? Just a thought. Its funny cause you always borrow money from me and make your mom pay me back.

the most i ever borrowed from you was like 20 bucks and cuz i was at your house and i didn't have my money with me (but enough with the excuses) also i wanna buy my uncles mustang (icould take it off him for like 500 or 600 if i wanted to) or i can use one of the THREE cars my family doesn't use (or i can be like the forty year old virgin and ride my bike everywhere!)

and yes i do have money,lots and lots of money!!! (but not too much)

im not gunna lie, its kinda annoying to listen to you guys argue over this, when ricky doesnt have any money cuz he spent it all on airsoft stuff, we can all point and laugh.

Alright, Birdman was right. Lets leave our ongoing argue to words and not on the forums where we should be talking airsoft. Sorry for getting so off track guys.

Anyways....I think it would be more wise to upgrade your internals before adding external accessories to your rifle. Because...than when you are all said and done, you will have perfect knowledge of what your rifle is capable of, and you will have played with it enough that you will have a much better understanding of what you would really like for your oh so awesome AEG.

Yeah, externals are cool and all, but when it comes down to it, they don't really help you any in being able to make that one shot count. Speaking from experience, I would suggest that you take a serious look at working on your compression, your spring guide (whether making it a ball bearing or not or whatever), and also maybe your piston. If you are planning on putting a big spring in, you will probably also want to have a rof that will match it, so a piston with good strong teeth wouldn't hurt any.

So in short, make the internals like gold, then get the externals to match it. Making that one shot count will give any airsofter more satisfaction in the game then any external upgrade could. =)

how about some stuff like this...

i might also get an AK or G3 length barrel and then use a silencer to cover it up, i haven't lokked overseas yet mostly because i dont want to pay shipping but i could probably find some good deals on ebay

edit: i did find them on ebay for a lot less

Yeah, the first one might do some stuff for ya'. I would get it to a knowledgable tech. before you buy anything though. Your compression might already be really good. You'll just have to test it and see, and the way you do that is by taking the gear box apart. But I would look into something like a full (or half) titanium tooth polycarbonate piston, instead of just a plain polycarbonate one like that one in the first link. Usually plain polycarbonates will get the job done just fine, but it never hurt to be on the safe side.

But yeah, definately internals first.

i know deepfire supposedly has a strong titanium tooth piston out there, and the guys at kastway airsoft have it for some repairs/upgrades,so i'll see what they have to say about it before i make any critical moves, although i do see them coming around soon.
