M14 miniproject

[Richthofen]

I am debating on getting a CYMA m14 and then getting a systema gearbox and tightbore barrel. Basically i would be keeping the body of the cyma, everything else upgraded. Is it a good idea becuase i can get a cyma m14 for about 120 and then a systema gearbox on sale at the moment for around 40-50 and then a tightbore for 30. not bad, building a m14 for about $200 plus labor for someone putting the stuff in. Good idea?

If you are going to do that get a used onto off Craigslist and change the parts you mentioned. Save your self a few bucks

Why would you change the gearbox? The stock one is plenty strong for most applications.

Because Systema WAY outperforms CYMA in terms of durability, performance, longevity, etc.

I think this is a good idea, however I'd recommend maybe an Echo 1, G&G, or a Classic Army for the 'shell' of your M14 project. Better quality materials and trades that way; don't want your body to give out while your gearbox is still running strong. See if you can find one used to save yourself a bit of money.

[Richthofen]

the reason i am doing this is to have an accurate but high power aeg so is the m14 the best choice or would a different gun like an m16 be better...what im basing this off of is barrle length, and normally longer barrel=more accurate. Correct me if i am wrong

I believe the reason why Ron, said it is pointless, is because it sounds like he is just going to get the gear box shell for the amount of money. If you could get a fully built systema gb that can handle a m120 for 50. then there would be a lot of dmr m14s on the fields and i would have a socom 16 at vanguard on the weekends. Pot metal is pot metal just look at the craptastic receivers on their ptws. So saying it "way outpreforms" is inaccurate. I'm willing to bet that a systema shell will last just as long as the cyma or a little bit longer, but not long enough to justify the cost of it.

longer barrel doesn't mean more accurate, it is a combination of barrel, hopup bucking, nub, bb quality, and fps consistency. If this is your first aeg don't be expecting a whole lot for range. Example my master series mp5 cant touch out to 175 all day. So say after you spend all that time and energy upgrading a gun on the cheap the range you are going to get maybe 225 if you are lucky. Thats only a 50 foot difference. how fast can you cover 50 feet? If i was in your shoes i would just buy a e1 m16 plastic body with ris. It is light and wont fatigue you. The reason why so many people run ars is that everyone has the mags and sharing is nice. This suggestion is based off the assumption of this being your first aeg. Correct me if I'm wrong. this is just my opinion on what you should do. IF you want more insight go ahead and ask that is what the forum is here for.

this is actually my 3rd. I have a dboys ak47 which, after it has been taken to the shop and all the internals revamped, is not bad. I also own a ECHO 1 scar which is pretty nice aswell. I just got done playing some people who could shoot me from one end of the cqb field at fort adobe to the other, and i figured it would be nice to have a pretty good distance weapon that is full auto. I have a budget around 300 dollars for this gun so i am looking at a few models such as a the echo 1 socmod m14, a g36 (not the C version), or a sg550, or an m16. In any of these guns i would want to replace the barrel with a tightbore, put a 130/140 spring in (so i can use heavier bbs to get 400fps) and then replace bushings, piston, reinforced gearbox, etc  and that is where the systema gearbox would come it because a full kit contains all of it.

"so i can use heavier bbs to get 400fps" the muzzle energy on most fields should be 400 ish with a .20. I would just take that 300 and upgrade that scar with a systema bucking and a 6.03 tbb. I can't remember what the scars shoot at but if it shoots at 370ish it should be around 400 with those upgrades, if you need more i would do put a oring air nozzle on it. I would use .28 bbs, pick which ever respectable brands you want. I'm no bb expert but that is the weight i would run in this setup. that would still leave you with 200 left over. How far are these long shots anyways?

I just came on to update my last post asking if i should just spend the cash on upgrading my 2 guns lol...and these shots are good 200-250 footers nd they would hit me consistantly too...yes my scar chronoes between 380-400 with .2s so i could get a tbb and upgraded gearbox for about 100-150 depending on websites/shipping and that would leave 150 for labor charge for apd to put it in and still thats 120 bucks left over

[icorus16666]

the gearbox parts aren't nessicary to get out to that range. with the 200 left over that i said with the parts i mentioned already. You can try and put a CA hopup unit in it, i would do some research on it before buying it to see if it is worth it. You should be able to make the 200 ft. shot with a 455 mm tbb and a non ported cylinder. You will probably need a barrel extension to cover the barrel. What is the fps limit at adobe anyways. Because you said it was a cqb field and i doubt they will let you shoot over 400 with a .20. For shot consistency you can go and upgrade all of the internals but the systema bucking should help after it is broken in correctly. Just do the barrel and hop up stuff first and see what your shot varience is. I would aim for 10-15 variance with stock gearbox parts. if you are at 10 fps i wouldn't go into that gearbox and just use it how it is as long as it shoots at the fps that allows you to play on the field.

the fps limit at adobe is 400. SCAR came with a good sized extension, so length is going to be fine. Now the main question is: New gun or Gun upgrade.

My mistake, must've misunderstood. As far as just the SHELL of the gearbox goes, I completely agree. No need to replace that.

Echo 1 STAG-15 A4
6.03MM Tightbore
m120 Spring
Polycarb piston and piston head
Systema Bushings
New Air seal nozzle
Steel spring guide


Would that work out well? Any other things i should get upgrade wise?

What barrel?  For 6.03mm, Madbulls are great.  If you can spend a bit more, Prometheus are nicer.  You might not see much of a performance difference between the two, the Prometheus will just have a longer lifespan since it's SS.  You can still put plenty of rounds through a Madbull though.  (it's not like it needs to be replaced every 40,000 rounds)

I know the JG Enhanced models come with metal bushings, not sure about the E1s.  I would think they do. You might check which size bushings the E1s come with if they are nylon.  

Keep the stock piston and piston head.  If the stock piston is the creme colored one, then it is very durable.    Just make sure the AOE is adjusted. Piston head is good too, you may just need to replace the O ring with a #14.  

A bearing spring guide is a good idea.  It should have a metal spring guide stock, but replacing it with a bearing one is a good idea.  Or keep the stock spring guide and add a bearing piston head.  (Element POM/Red piston heads are great)  

New nozzle is always a good idea.  Stock clone nozzles typically are leaky.  

Reshim and regrease the gears too while you are at it.
