AK Double Eagle Modification

[cowry]

We try to upgrade the following parts of the above subject: metal bushing, SP120 spring, Marui stock piston head ported and properly shimmed it. And plan to install modified motor in the near future. We will let you know if the unit can withstand the performance of the spring. plan to use it on the hi end competation. ano kaya fps nito. Anybody tried the said upgrade? share naman o.

My experience with the double eagle AK has been nothing but woe and pain...

Unlike the CYMA AK, the DE has a weak motor that couldn't crank the X130 spring(even with large batts). Installing a strongger motor is a good idea. Heck- even the old BE STEYR AUG motor is a better alternative to the stock motor that came with the DE AK. Be warned however, there is no MOTOR ADJUSTMENT screw in the motor cage. You'll have to adjust the motor by using "spacers".

The weak part of the gbox is it's CYLINDER HEAD- it's a clear plastic(polycarb?) part that is often already broken by the time I open the gbox. A few more thumps with an upgraded spring will easily break the said part. I suggest upgrading this part right away with a stock TM or CA cylinder head(para mura lang).

Another problem point is the trigger contacts. The metal is of dubious quality and they easily overheat- causing the contacts to BEND AWAY from each other. Another reason for the overheating would be the very small wire guage that they use. The wires heat up easily during full-auto fire... eventualy overheating also the motor and switches.

Stock FPS of the DE AK i worked on was around 250-260fps. Installing an X130 spring pulled it up to 330fps. In contrast- a CYMA AK clocked 300+fps stock and jumped to 370fps+ with an X130 upgrade!

Tip- use a CYMA AK for your project instead of DE.

SIR, PAGCY BA REINFORCED NA GEARBOX? SAME AS THE SPETZ?

[rambo]

haha! seems lamyak mga natyempuhan DE ak's ni sir stans.

anyway i have a DE m86 and believe me or not my stock motor can crack
a sp150 spring. isa sya mga na-unang batch kasi. a fact that
the recent batch do have weak motors which can only handle sp110 max
while the first batches do have stronger motors capable to crank sp140-sp150
this was posted at FAS by Tuni dun sa review section.

and so far my DE m86 still is doing good...almost 5-8 hi cap mags each week
sa kaka-plink at test fire sa bahay at sa laro.

btw- stock cylinder assy pa rin gamit ko dito but with magic teflon at oo
matibay din sila as far as i can observe since every week check ko sila.

heto proof hehe...

make sure you have divx codec installed.

ang ayoko lang sa DE ak ko eh lamyak yung pistol grip at foregrip very squeeky
which can be remedied by thickening certain area a little.
so far yung pistol grip pa lang naayos ko by simply putting a rubber bond kung
saan kokontak sya sa lower reciever. fast remedy but it does work. now it
feels much stiffer.
yung isa kong inayos na de ak ok naman mas solid sya kaso m86a naman
yun alang burloloy type.

@sir vernes - ingat lang sa pag modify nyo. almost the same set-up tayo. i filled down some internals of the ak body just to accomodate my awg16 wires kasi nung stock wires pa siya(w/c is very thin) umiinit agad ang motor and masyadong malambot ang contact point sa trigger, lumalayo at nawawalan ng contact. tama si sir stan, grabe ang hirap na dinanas ko sa de-ak na yan.

[vernes]

@ miklo- sir g try na nmin change yung wires kc yun nga sa mga nabasa nmin ang sa mga sabi2 nlng na manipis nga yung wires nya...


sir wer po tayo mka bili na mura na cylinder head yung matibay?...basta sulit yung money para sa upgrade ok na yun.....tnx

[vernes]

whoooo grabeh sa wakas gumana na din yung ak nmin...battle tested na din and it work..hahaha salamat gyud!!....nxt time pa chrono na nmin...weeeeee...more power sa lahat....
