JG M4 shooting 550fps... with a range of 350ft??

[malik]

Is this possible? I was talking to someone and he claimed his JG M4 shot ACCURATELY over 300feet. And that's with a stock barrel. Not only that, he said he is running a 550fps spring with a Matrix GB shell and systema cylinder and some other stuff... No new barrel, still a 2 piece hop-up. I that possible? I think he is either lying or just doesn't know distance... I might believe the 550fps, but won't that kill your AEG?

At 550, if you know what you're doing, you can push the range out to 100 yards. Maybe even more with the right BB's, but I'm pretty sure you'll only get about one hi-cap (if that) out of it before it starts having internal combustion. IMO V2's are possibly the weakest Gearbox design (I don't know about V1's).

As far as accuracy goes, you can make a gun extremely accurate with a stock barrel at that range, but it is pretty difficult.

I get 75 yards accurately (i.e. 9/10 on a paper plate) with my DMR shooting 400 (.2s). The bucking I have in it is a custom bucking I made that is similar in design to a firefly bucking... just better.

In short, yes it is possible, but with an M4 it isn't at all practical.

Yeah 550 is going need something better than a matrix brand. That's a scam or he is lying. There is no way he is able to hit a person at 350 feet with a stock barrel.

Is this person on AP? if so you should put his user name up, this is some sort of scam.

What good would that do?



And "accuracy" is relative, he could think that accurate at 300ft is hitting a 3ft round circle.

The one JG m4 I have worked on was eerily accurate stock, at the time it beat my G36C that had a firefly bucking and tbb.

You could also consider if he was using .12s for chronoing, or horribly misread a poor man’s chrono test.
550fps is plausible, but not easily done by an amateur.

But who knows, the proof is in the pudding. If you want to see if he is lying, go shooting with him.

[malik]

It's as kid at school. He seemed to know what he was talking about... Although, he did all the updates himself. There is no way I'd play with some kid ( a "cowboy" from the impression I got from him) that had an automatic firing 550fps... At least he admitted that no serious fields would let him use it...

Let people on AP know that there is someone out there that is kind of shady?

[G36 FTW]

Ahh

Well, in that case you might as well wave him off. It doesn't really matter if you aren't going to play with him.

Although I must admit myself it would be interesting to see what he did if it was true.

[Beran]

pics or it didn't happen. there's all kinds of bullshit floating around, you take it at face value until you see proof.

250-300 feet hitting a man size target is plausible with an AEG, ive gotten repeatable hits at 275ft with an M16 shooting 400. 350 feet is absolutely pushing it. you might be able to hit a car or a person with luck, but claiming that he is able to repeatedly hit a person is very very suspect to me. getting 550 fps out of an electric gun isn't that hard if you know what you are doing. ive seen an M14 get 530fps on an M130 because we worked the compression good enough. once you get a BB over a certain velocity threshold though, you start to lose accuracy. its a spherical projectile with a backspin on it. if you push it fast enough, it becomes unstable. ever fired a lighter BB from a high powered bolt gun? they start going all over the place, taking turns in directions that don't seem possible.

if you ask me hes probably full of shit, or using .12g BBs and fifteen year old bravado and logic.

Damn, I'd love to see a AEG that could even get 200 feet (and measure it). 200 is pretty far, but I haven't even heard of an AEG getting above 250. I do believe you on the M14 though, good compression is everything.

[Sleepy]

Accuracy is a relative thing. My idea of a reasonable expectation of accuracy is that, at a certain range, I can expect, say, 2 out of 3 rounds to hit a man sized torso.

As for the 550FPS and 300yards with a stock barrel, I'm tempted to call that bullshit and say he just wants to one-up people. My gun shoots further and faster than yours, and that makes me better than you. But you really never know. Ask to borrow the gun, grab a chrono and some targets.

[GacktC]

I can see an AEG can yield 550FPS & above with stiffer spring, but how long the stock mechbox can last?
Stock barrel are usually range from 6.08-6.09mm, G&G has 6.04; that's what they claimed. Since JG is made in China with less than less QC, maybe he got a cream of the crop M4 with higher FPS than a stock Sys's PTW~~it takes all kind.

[malik]

So, possible, but highly, highly unlikely. Even if it could shoot 550fps, isn't that really hard on the internals? He even claimed it was pretty well silent. He said he has upgraded the gearbox... So it was not a stock GB, just a stock hop-up/barrel. Matrix shell, Systema silent cylinder, didn't say anything about new gears...

[TurtleFace]

Even at that velocity I would highly doubt that is possible. My bolt is shooting >= 550 fps, and I'm not hitting 350, "accurately" or no. Keep in mind that's with a highest quality tightbore, bucking, and everything else that makes a sniper rifle good.
Also, I just so happen to have a JG M16 with a 510 mm tightbore barrel shooting ~400 fps with an upgraded bucking, and performance increases are nominal, but definitely not tripling the range of the gun. Kid is either a) full of shit, b) retarded, or c) both.

I'd say C. Both!

Hang out in a gym and guys lie about their bench press, hang out with a car club and guys lie about their 1/4 mile time, hang out with airsofters and, well, you get the idea.
