  1. Lighter bolt, lighter buffer, stiffer recoil spring.

     

    The bolt in your Inok is steel. Your ROF will increase if you switch to an aluminum bolt.Your recoil will be diminished. If you're trying to achieve an ROF comparable to an M4, it's unheard of for WAM4.

    Thanks, I heard of a Viper Speed Bolt Carrier Group but couldn't find anything about it.

    I also saw a youtube video of someone only replacing the original buffer with a speed buffer.

    Know about any of those?

  2. KWP, any feedback from your friend on the JG mag so far? Anything of concern? A lightened mag is good news but it makes one question the durability.

    AFAIK, seems like an all better AGM style mag.

  3. Nice pics and video KWP!

     

    How's the quality of the bolt carrier? Especially the area that engages the bolt catch. Does that little area stick to a magnet? I'm curious because if that part isn't steel then and since the JG bolt catch works all the time then the bolt carrier is going to wear down alot. To the point where it won't catch anymore. However it looks way better than an AGM so no worries...

    Glad you like them. There's no tiny steel piece on the bolt carrier, only the bolt stop has it.

    As for shipping, US$58 is the actual no-nonsense shipping via EMS Speedpost from Hong Kong to the USA for the JG.

    Anything beyond is the retailer's hidden rip-off margin.

  4. cheers for that, if you get chance to take a closer look at it wouldn't mind finding out following:

     

    Seperate barrel extension? (AGM moulds it into the upper but not sure if JG will have been able to do that on a plastic upper)

     

    WA compatible buffer tube thread? (AGM has milspec tube but with a thread of their own)

     

    Buffer tube diameter (ie does it take RS/AGM/WA/G&P stocks or does it take AEG ones)

     

    One peice alloy outer barrel, or multi part design?

     

    Outer barrel using a fat collar as per the WA and AGM 061/062, or thin collar as per RS, G&P and AGM063/64/65

     

    Metal end cap between front sight and handguards?

     

    Quality of the front handguard - keepable or straight in the bin quality like the ones on the AGM?

     

    Just trying to get a handle on wether it would be a better donor for a '3rd party MBK and custom build' than using AGMs

    I will have to look into most of your good questions to answer them. Maybe some of the below pics may help, but I will try to get the answers if I can. But for the outer barrel I think it's one piece (I didn't look under the sling swivel mount though). The handguard is nylone type, similar to the CA ones, better quality than the AGM for sure. I just didn't like the gaps between the two pieces that were a bittle too large for my taste.

     

    Great news!

     

    Please check do the BCG groups are interchangeable between the AGM and JG type. Is the black plastick reinforced and more durable than the white sh** that the AGM have. That part broke within 200 bbs for me.

    I tested both.

     

    JG BCG inside the AGM:

    The complete JG Bolt Carrier Group can be used in the AGM. It's drops right in and cycles just fine. The test AGM had inconsistencies with the bolt stop function with both the AGM and JG BCG.

     

    AGM BCG inside the JG:

    The AGM Bolt Carrier Group seems to be a little wider but I could still drop it into the JG with a little friction.

    Properly cycling the JG with the AGM BCG was impossible. Every time the BCG got stuck somewhere halfway inside the buffertube and you had to hold the gun muzzle downwards and slap the buttstock so that the BCG could return home.

     

    Wow. Wow. Wow. Wow.

    Do want.

     

    So do you prefer your JG over your AGM?

     

    Sorry if I missed it, but how is the kick?

    It's not my JG, a friend let me test and compare it with the AGM.

    The better mags and the functioning bolt stop alone are a good reason to go for the JG, imo.

    But I don't think anybody would like to keep the cheapo looking plastic body and I would also have to replace the handguard with a RIS as I play USMC style. :)

     

    And yes, it kicks hard just like any WA design GBB rifle, but I missed the clanking sound of metal against metal when the gun cylces or when you cock it. That's very important. :D

    And a couple more pics 'n vids:

     

    Lower receiver parts, bolt stop is spring loaded:

    Gas tube is secured by a pin in the gas block, so it won't shake loose like on the AGM:

    Hopup dial had a sloppy feel to it and was difficult to turn and didn't seem to have any effect on the hopup rubber:

  5. The Jing Gong M4 GBB rifle is another replica of the WA design.

    Just like the AGM M4 GBB it's targeting the bottom segment of the market.

    It's even a little more affordable than the AGM (e.g. at this date an undisclosed shop sells the JG for US$85 and the comparable 061 model from AGM for US$110, both plus shipping).

     

    First thing you notice is how much lighter the gun is compared to the AGM. Not only the gun itself because of the plastic body, but the 300g less weighing magazines are a tremendous difference (JG: 500g, AGM: 800g). The magazines from the outside are pretty much the same design, just the finish is a lighter gray. It also has the bolt stop selector switch allowing you to activate/deactivate the bolt stop function. The mags were a tight fit in the mag well, but were no problem to insert or take out. Pushing the mag release didn't make the mag fall by itself. Just wished there is more positive and noticable feedback when the mag has clicked into position. But no mag swelling or other problems. The BB spring is stronger which should benefit the bolt stop function (Bolt stop worked 100%). Filled with Green gas no leaking was noticed. If there is, it must be insignificant. At least I couldn't hear any hiss, nor did I experience any excessive performance inconsistencies while firing the gun or chronoing.

     

    The body is of reinforced plastic and makes a sturdy impression. The trademarks are a different story. Well, the trademarks themselves aren't that bad, but they are framed by a thin line that got onto it during the stamping process, I guess. That gives it all real cheapo look.

     

    What about the metal parts? Pretty much the same as on the AGM. What should be metal is metal except for the receiver body and the buffer (which is also plastic in the AGM). The magnet test showed quite everything must be some kind of alloy, but to my surprise the magnet was attracted by two parts: the flash hider and the lower part of the carrying handle. The fire selector sits much tighter inside the receiver and needs some force to turn it, but clicks nicely into the positions and best of all is that you cannot accidentally push it out like on the AGM, it's a real tight fit. As expected all the internal mechanical parts are not steel. The bolt is made of black plastic fitted with a copper nozzle. I couldn't check the hopup yet, but looking down the barrel I could see the rubber protuding inside of it and it seemed to stay in that position. Turning the dial though didn't seem to show too much effect. But that needs to be tested more thoroughly.

     

    Worth mentioning is the bolt carrier does not have that tiny steel piece to reinforce the part of the bolt carrier that slams against the bolt stop. The bolt stop itself though has that steel piece, just like on the AGM, and is now spring loaded. Along with the strong magazine spring this seems to have ironed out the bolt stop malfunction some AGM users experienced. At least during my testing it always engaged after the last round shot or when cocking the gun on an empty mag.

     

    There's not much to say about the lower receiver parts at this point as this would require an endurance test to see if, how and when something breaks. But so far they look the same as in the AGM except for the bolt stop that is spring loaded now.

    The recoil buffer is a black plastic piece and the recoil spring metal (and if it matters a shiny piece of metal resembling the looks of stainless steel which it certainly isn't).

     

    Chronoing with green gas at an ambient temperature of about 22 deg Celsius showed results of 390-420fps (1.4J). You can see in the video below that there were some misfeeds.

     

    Edit: Yes, it has a realistic looking metal gas tube going all the way from the gas block into the receiver body. The handguard is of decent plastic and there's no hassle with the delta ring to remove or put them back together properly. The stock was pretty wobbly.

     

    And now pics 'n vids part 1:

  6. it is very hard to insert the 5KU ebybanned mags into the magwell, you would have to file down some of the inside parts of the magwell in order to make them go in easier. performancewise i cant say much at the moment, they leak a bit, just like the standard mags and they are not as loud and crisp as the standard ones.

    yup, can confirm that. Had a hard time inserting them and freeing them from the mag well.

    Other than that they are okay and are some kind of improved AGM mag with stronger spring, full metal exterior and just like the AGM don't leak on green gas.

  7. I don't really see a problem. Whether it's "only" 30 pages or 300 pages. You wouldn't browse every single page, but use the search function. In either case the machine is doing the work for you regardless the number of pages.

  8. Wow, that KJ rifle seems all steel inside and outside.

    That's mighty impressive and looks like it could be quite reliable out-of-the-box.

     

    But I can't help it, I ventured into the GBBR world for the kick of more realism and simplicity.

    Reliability sure, but if it's just about that, my AEG would serve me just fine.

    If KJ just used the WA system, I would have said we have a winner.

    But just like the WE system, I hate extras that make it look funny and unrealistic to disassemble/assemble.

    The KJ has too many mechanical parts, a rubberband what the fcuk???, a hopup dial that is certainly ergonomic but ugly to look at, a nozzle that protrudes out of the bolt and the bolt itself doesn't look like the real deal.

    That's too much to bear with. A pity really as the KJ seems promising, but only reliability wise.

     

    I see it like snorkelman and Stealthbomber:

     

    {...}

    Going by the photos posted on the KJW I can get at least some of them in steel straight out the box in a 290 dollars or so gun

     

    On the AGM I can add ALL of them to the 120 dollar gun for 80 bucks right now, and probably for less than 60 by this side of chrimbo

    {...}

    {...}

    I hate to say it but I hope the KJW gun doesn't turn out to be very reliable or accurate.

    All it's doing is messing up a market that already desperately needs to sort itself out.

    Beyond that, I'm not keen on the ugly hop-up adjuster or the strange mechanism so it'd almost be a shame if it did turn out to be the most practical gun of the type.

    I know that sounds a bit harsh but it's just starting to feel like the whole market is gonna go bonkers to me.{...}

  9. The new 5KU or SK mags have a stronger spring and seem to engage the bolt stop no problem. The one I tested were a pretty tight fit in the mag well though.

    The hopup replacement for AEG barrels:

    ae25a669.jpg

  10. Nice to see a cheap reliable platform finally coming out of the cracks. I know people are going to *badgeress* about, say the AGM, but I consider it to be a non contender. When I see reports of critical parts failure within a few hundred rounds, and then several hundred dollars in repairing parts that are sub standard, in part of a flawed system, I really don't understand.

     

    Be interested in picking one of these up to be honest. The power would need to be sorted, but its not a particularly difficult issue.

    You're right, don't compare the AGM, it's in a class of its own.

    But as you mention substandard parts that need to be replaced on the AGM. That's only the mechanical parts inside the receiver because they are made of alloy instead of steel and those can be upgraded with CNC steel parts for cheap. Now to the KJ: As far as I can see Donut's review didn't mention if the KJ's mechanical parts are made of alloy or steel, so I would wait with your judgment. ;)
