Need a components check

[Santa]

Hello guys.

I have a TM AK47 and the main idea is to have smth reliable (smth like real AK proof :-D :cheers: )
I know it will be wasting money in some parts. So here I need your help.
Can you tell me if some of these parts will not make ANY good, pls.

I already have:
- Systema spring bearing guide
- Prometheus 6.03 inner barrel

I gonna order:
- Prometheus Non-Liner Spring MS100 (340fps by itself + considering that other parts will add 10-20fps which is enough)
- Prometheus 6mm Bearing Axle Hole
- Systema Shim Set
- Systema N-B Cylinder Type-1 for AK47 (90% I don't need it)
- Systema Silent Head Set for Gearbox Ver.3
- Systema Air Nozzle for AK

Cheers

Both are good.

That spring is fine.

- Prometheus 6mm Bearing Axle Hole (Not needed, you want regular metal bushings, not the bearing ones)
- Systema Shim Set (Not needed)
- Systema N-B Cylinder Type-1 for AK47 (90% I don't need it) (Not needed)
- Systema Silent Head Set for Gearbox Ver.3 (Not needed)
- Systema Air Nozzle for AK (Not needed)

There you go. Reliability means keeping it simple.

Hmm... can you explain reasons for these two? As I understood they suppose to decrease a load?

[Greylocks]

Bearing bushings are only good when you want a really fast ROF gun. Same for high torque gears; they are meant for guns like MP5 with small batteries and strong springs.

Silent head is simply not needed. Not bad to have it, just not needed.

What you need; metal bushings, a spring. The rest is fine. Check the stickied posts. For the record, I own two Marui AK's, both work fine.

I got my TM AK-47 in the winter of 2004, it was my first gun...it went through 15 thousand rounds of BBs before I have to do a full tune up again.
Just give you an idea of what I had and comparing to the list you have above:
120% PDI spring.
Guarder metal bushing
Guarder clear hope up buckling
Guarder metal spring guard
Stock piston and piston head - with four holds drilled for improve air circulation.
This set up never failed me once in any game situations and I am not exactly the 'fire discipline' type as my team mate often ask me to lay down cover fire with my AK.
Very 'big bang' for the money I must say.

Longshot, that too is a fairly plain setup. You added a few more things than I did, and I must say I never tried to drill the piston face.

Overall, it's one of the reasons I love the AK series. It's a simple and tough gun.

Droc gave raving reviews about the ICS version too, so I guess the basic design is good enough.

Ok. I got it.
Thanks a lot!!!

I'm gonna add one thing you didn't have in your list: dump the crappy Marui hop packing and install a good quality aftermarket one (I usually use the Systema or Guarder ones, but like a lot of components there's a good degree or personal preference that will go into your choice).

It's not someting you need, but my experience over the years has been that it does help: a "grippier" packing doesn't need to be applied as high to induce spin (I find Marui's packing to be very slick). Reinforced ones should also stand up to the upgraded spring better, although that's debatable. Generally however, they work better with heavier BBs (.25g) -- but could be problematic with .20s (the way my MG36, for example, cannot shoot .20s, even with hopup turned off completely; BBs will still curve up slightly after around 20m). But yeah, point in case, with heavier BBs you can get some range in without having to up the velocity as much, specially when combined with a thighbore inner barrel.
