Getting my M15A4 all straighten out.

[Buds and Suds]

K, I want to be all setup for next year and want my rifle running smooth as silk.
Heres the setup thus far.

CA M15A4 SPC w/ tightbore barrel and M120 spring installed. Mechbox came with metal bushings.

I have a Deepfire polycarb piston, but not installed. And a Deepfire piston head with super O ring and bearing on the way. So far Ive had an arc on my trigger switch, but the replacement is on the way as well.

I want to go with what was suggested to me, to get a "good setup" and am looking at downgrading my spring to a Prometheus 110, even though I really like my M120. MOSFET has also been suggested to me but Im thinking ill do a bit more research before I tackle that.
Anyways, what would a wise veteran like some of yourselves do with this rifle? And are the parts I have already going to be good? If not ill resell them while they are still unused.

Do you have it setup the way you want? (vertical grip, m203 launcher, red dot, reflex sight, etc etc).

I want a M203 for sure, but since its expensive im waiting till Spring to pick it up, I dont need it right now anyways. also am going to get Ret dot or Reflex, havent decided cause I dont know the pros and cons of each yet. Im basicly just sticking to tweaking the internals first to find a balance of range power and durablility. I want everything to run like a well oiled machine before I start adding the gucci gear onto it. Function over flash right now.

Prometheus 110SP in one of my MP5s has served me VERY well this year, no stock mechbox breakage, consistant 365fps out of it (229mm barrel) and because of the Guarder clear hop up rubber being somewhat swollen, at just above full off setting, I can get my 0.28g BBs easily out to 200ft (mind you, there is almost a 2ft spread, but still...........)

that was a different gun he was referring to.

yea srry deleted my post. he wasnt referring to a different gun he was referring to a different spring PDI as opposed to prometheus.

So woops ma bad.

Here is what im planning on adding..

Setup #1 with Madbull M120 (already own it)
http://www.airsoftparts.ca/store2/in...roducts_id=523
http://www.redwolfairsoft.com/redwol...l?prodID=17954

With this, should I also upgrade cylinder and cylinder head?
I heard that with my rifle, it should be able to take a M120 and nothing else would be needed. Misinformation?

Setup #2 With prometheus 110 (wondering if I should get it instead)
Same as above cause its already ordered.

Im really big on reliability, I love what ive seen my M120 do so far, but recommendations to switch to 110 cant be ignored. I just need to know if I should add, if I got the wrong kind of parts, a better brand name....ect ect

good tread, I am also planning on purchasing the CA 15a4 and this will tell me what to upgrade from the start....

Ya, I know, but if I get all that out of a shorter barreled MP5, he should see at least equal performance out of a longer barreled one, as well the "V2 friendly" reference I made still applies.
