re CA body on my Echo1 m4a1

OK - here is my project -
I currently own an Echo1 m4a1 v1
Madbull V2 black Python 6.03 tightbore
DE (UTG) red dot scope (front lens got shot out during a game, but it still works...
3 hicaps,
3 9.6 1400 mah nimh's
1 8.4 1100 nimh

so far it has a red dot scope on it. (ignore the laser mounted on the hop up cover.... it didnt hold, but it did look cool while it lasted...)


i recently got a CA metal(der) body. with a full metal RIS system.

now, to get the ris on, I had to swap the barrel over from the CA, as the front sights on the echo barrel are a little too close (not long enough to fit the RIS by about a half inch). and they are set in a grove, and cannot be moved w/out heavy mods to the barrel.

I am also working on replacing the body, but that will require a new CA hopup, and mag well internals, but it looks like the Charging handle and hop up cover door will switch over no prob. the Gearbox will be an easy drop in, and the motor should not cause a problem either.

when she is done, she will be a sexy beast...
I will keep you guys posted - and Great site - i am glad someone created the Echo1 owners Group - !

Hooya!

cant wait to see the outcome... was looking to tranfer mine over to a metal body once i get it.

with the RIS (PEQ didnt get delivered to the field, but its gonna come w/ a new hopup unit and magwell assy (I guess they are the same peice? will see))

ok got the lower receiver on, got the upper on, noted a few things that need modded, the bolt catch needs a little knob removed, and the charging handle is a bit diff. but, it can be mounted , yo just have to go CA style and release the hop up cover manually. the mag catch fits perfect.
I am ordering a NEW tm / ca full metal hopup unit w/ feed tube for $25 from evike along with the madbull fishbone hop up buckling $12 from evike.

most likely going with a 510mm tightbore and a suppressor (barrel extention)
as well.

here are some pics of the transfer and progress.






ignore my large feet. thats the echo1 gearbox in the CA body, no barrel or hop up yet, and the motor is still on my desk, but thats the Echo1 dust cover, note - on the other side, the trigger pin will need to be dremmeld of, as it doesnt go all the way in,(i am gonna work on that later, and i still need to move the charging handle over if i really want to, although at this point, its gonna be useless. and i still need to file down the knob on the bolt (again a useless item, just cosmetic.) but there it is, an Echo1 in a CA body.

Very nice, looking good. I'm looking to do more or less the same thing to my Mk12 mod 0 (A&K based), although I think I'm just going to replace everything (make it completely out of aftermarket parts) and use the A&K as a loaner gun. Finally got my M3 scope in, but can't pick it up until I get back home As far as the scope goes, I vote you mount it on the carry handle, RDS looks much better that way.

i dont have a scope mount on my cary handle.
ordered my jbu full metal supressor, a full metal hop up unit, 2x guarder 50% hop up bucklings (so I have an extra down the line) and a UTG ergo forgegrip. also got the Echo1 PEQ battery box. (had to get the echo brand cuz its my echo1 lol)

Very nice!

Good to see more people dressing their Echo 1's up in full metal. I can't wait to see the finished product!

metal hopup , and other stuff will be here on monday - so expect some pics on either mon nite or def by tues /wed.

and ps the body - only cost me a BE g36k

OK here we go again -
the only part that is still on order is my Echo1 PEQ (cuz well its from evike and i got that lovely yellow paper instead)
but here is the finished results -
*special thanks to Munky for assembling the G&P hop up unit for me, and re-seating the motor*

Very nice, looking good. Looks like you got yourself a nice front grip now too.

it has
CA m15a4 RIS body
echo1 retract. stock / buffer tube
echo1 m4 (2006) Gearbox w/ the m110 spring (stock)
madbull 363mm 6.04 black python v2 tightbore
G&P full metal hopup unit and bucking (the guarder 50% was way too loose)
Metal carry handle scope mount w/ DE red dot scope
UTG ergonomic vertical grip
JBU full metal suppressor
1 echo1 hicap
2 A&K hicaps
1 ICS hicap
3x 9.6v 1400 mah nimh batteries
and an Echo1 PEQ on backorder

total invested now is approx $400 between the orig gun, upgrades and accessories. not to mention the ammo.

future upgrades are to include new piston / head, bushings, spring guide, gearset and possibly reinforced box. - but I wont touch that till the nylon bushings go out and i chip a gear tooth or what not - I want to see the durability factor of the stock gun.

thats pretty sweet i might do something like that 2 mine

yeah, she is quite sexy now... and she hits hard - I need to re=chrono her - she was at 357 stock...

i wanna chk out the range w/ my new hop up -

PS - you all should replace the hopup - its kinda lacking (well mine was)

yea man thats looking good im buying echo 1's spr kit cant wait till it gets in

so you like that body alot ive heard bad things about the ca bodies but i really like them and im thinking about buying one

wow thats an old post. lol
since then.. this gun has undergone some severe changes..
basically.. its no more.
lol
i ended up using a GP zombie killer body. dropped in a systema gearbox, added a dboys casv, and an echo1 614 outter barrel with a kings arms hopup and madbull v2 tightbore.
used an ics turbo3000 and a dboys crane stock w/ battery for final touches.
