I picked up an ER-25K body through a trade for tech work. I have a mechbox and parts to get it to 450FPS but I'm not really interested in AEGs anymore. I would consider doing this if I had to or at the request of a buyer if I sell this. For now I'm thinking of replacing my finance's JG BAR-10 with it, which will give her a little more role flexibility and a higher volume of fire. The BAR-10 might find its way on y'alls commerce section if it doesn't sell on alabama airsoft quickly.

I am missing a hopup unit, barrel, pistol grip, rear sight, flash hider, suppressor, mags and mechbox. But, not bad for free. Below I have some questions about accuracy upgrades. I'll be buying over seas if its a concern.

Any suggestions on M4 hopups? This will be my first replica to use a M4 hopup but please, tried and true only. I was thinking of a King Arms.

I am thinking of using a 407mm 6.03 Prometheus or PDI 6.05. I'm looking for just accuracy with the barrel and not a velocity boost. Is there an optimum barrel length? I'll need a flash hider so a barrel extension in not out of the question. Anyone have a SR-25 suppressor up for grabs or where to get one?

I will need a hopup bucking too. Anybody have a suggestion? I am think about using the KWA 2GX bucking. Anyone have experience with the firefly with the firefly flat nub?

This will be one of those works in progress. That will not be completed quickly. I'm thinking that this should last me at least a few months.

Thank you for all the input,
mateba

PS: 200th post, woot!

For some upgrade parts I would suggets

Hop-Up: MadBull 3-1 Ultimate

Hop-Up Bucking: I use MadBull Blue in my SCAR to excellent success.. but I have seen great performance in other weapon systems using the KWA.

As for the Barrel I would custom match that to your cylinder.
there is a guide posted in General that gives you the equations to figure that out.

Ask Yankee, He just tuned up his SR.

Mateba:

Hop-up/ barrel setup:
Madbull Ultimate 3-in-1 w/ Firefly Soft Type(V Bucking) is what I run in my SR-25.
As for the barrel, I run a madbull 6.01 in mine with decent results, though I may step it up eventually, I was just on a tight budget.

I would run a 509mm barrel through a suppressor for optimum length. I would go with the Prometheus 6.03mm, 509mm long in your build.I assume your outer is only 407mm long so I think you could get any suppressor(unless you want that SR one) and just put it on(so long as the threading is correct). That is what I did, you can check out my SR-25 in the gallery.

So far though, my rifle shoots beautifully. It sits at 450fps if you were curious about that.

Let me know if you need more information.

Mainly just concerned about which m4 hopup is the best. I have had two replies about the madbull 3-1 now, is it that good or are the Marui clones that bad? I don't want to run the barrel outside the flash-hider because I would like to remove the silencer. I don't think I will use it all the time. The ER-25K does take a factory length barrel length of 400mm but I think with a longer muzzle device I could add an inch or more.

Cosmetic opinions anyone?

Another M14 flash hider which will allow me to use my KA QD can I have already.

Works with this set.

A SPR flashider which would allow another 2+" of barrel.

SCAR-H Flash hider and can combo might be a good compromise but more cash.

Picked up a few parts:
King Arms hopup unit
Classic Army Tango Down grip
Buffer tube screw and spacer
one mag
body pins

I wish I could get a M93 stock for under $60, o'well.
