||Ok I just quickly would like to say i have a JG sg1 and a classic army SAR, my JG is about the same on the face value, IE: rof, fps, general function, but inside the gear box different story. but Im really here to explain the fine differences over all. you can read the basic stuff any where, this is the nitty gritty.
the JGs wiring is crumby copper vs CA silver. and CA has secondary connectors, making it easier to wire the stock.
CA stock is more robust while the JGs is attached using smaller screws, this is a known point of failure for the g3a3 line in general.
the inner barrel on my JG was RUSTY on the outside! the flash hider and the front set is made out of some heaver pot metal (apposed to CAs lighter aluminum) which was all rusty in side of it, eeeww.
the charging handle of the JG is supported my plastic, so you cant 'HK slap' not a big deal, but it you leave it 'up' it tends to bend the plastic, not fun.
the JG does have that cool safety leaver that lets you see whats its on from both sides, but OMG DON'T LOSE THAT TINY SCREW!, CA dosen't have that, but it is a way simpler mechanism and much easy to reassemble.
The front bi-pod on the JG its the wiggle capital of jiggle city USA. If you put it up and down like 3 times, it will probably wonk out on you and need screwing, sure you can take it off, but the plastic for the hand guard just just plain crumby. the CA front hang guard if over all made out of way heaver ABS and the bi-pod is actually function able.
JG uses wonky pushpins that you gotta screw down, they are a little rough on the plastic, CA uses nicer push pins that are much stronger and is like the JGs front pin, no screw driver.
CAs metal body lets the whole front section of the gun have a simpler stronger attaching method, the JG needs all sorts of nuts and bolts and such.
a HUGE WTFunky potatoes on my part was that JGs cylinder was PORTED for like a mp5, there where major FPS loss, and a pain ultimately to fix, HOPEFULLY this 'new version' pays a bit more attention. SIGH! it also sports cheese ball plastic bushings , the echo1 version adds metal ones though, worth 20 bucks extra?
even IF you buy the TWO necessary metal body kits for the JG (front and receiver) the CA still has more metal, the 'SEF' trigger group is metal and the bit that holds the stock pins, also metal, the MBKs that Ive seen just don't have that cus of the 'neat' selector leaver that is on the JG/TM and the different style push pins.
Maybe you COULD rewire the whole thing, reinforce the stock, replace the flash hider, buy $150 of metal kits, and live with plasticity bits, enjoy the annoying/neat selector, just never open the gear box (clone compromise city) or get a new expensive drop in GB.
but really you probably wont, and like I did, if you really care about that stuff you'd just buy a classic army or Tokyo marui to replace your JG
I still love my JG, its just not displayed as proudly as my ultra babied classic army.
I'm giving it a three because I simply out grew it and wanted more. but if your a noob, go nuts its super cool, id suggest something else tough, but noobs don't listen anyway and will probably yell at me for ranting.
Read a book, that's how they end stuff, you probably don't know that cus you don't get that far.
