Mental Medic Posted August 30, 2009 Report Share Posted August 30, 2009 Yeah, I know, but maybe if you gut it, and try a new shell, you could fit some kind of fiberglass insulation inside. It would help a lot. I think, :/ But the fiberglass would take up much needed volume for gas. Now if they made a Pmag....... Quote Link to post Share on other sites
Amadem Posted August 30, 2009 Report Share Posted August 30, 2009 Thermold appears to be more practical in GBBR's because they don't have as bad a cooldown compared to metal mags. But the KJW's Thermold mag is metal made. Quote Link to post Share on other sites
Mental Medic Posted August 30, 2009 Report Share Posted August 30, 2009 But the KJW's Thermold mag is metal made. Really? I was under the impression that it was some kind of plastic. Does the mag have an inner gas reservoir? Quote Link to post Share on other sites
BrooklynBorn Posted August 30, 2009 Report Share Posted August 30, 2009 Really? I was under the impression that it was some kind of plastic. Does the mag have an inner gas reservoir? Wouldn't it have to have one? Since it's a gas in the mag gun. Quote Link to post Share on other sites

t_hum Posted August 30, 2009 Report Share Posted August 30, 2009 The magazine has an internal reservoir which is metal on every side except the bottom of the magazine. However, the plastic is very durable and thick. I wouldnt worry about the strength of these magazines. The thermold design has no impact on cooldown. What really prevents cooldown on these guns is the fact that the magazine contains an expansion chamber like the top of the line WA magazines. Quote Link to post Share on other sites
Kai_Wolf Posted August 30, 2009 Report Share Posted August 30, 2009 Does anyone make different body kits for it yet? Im not sure if the body was WA compatible, but one with trades would be nice. Raven, yours seems to be Magpulled out, including the receiver. May I ask, if not already stated, where you bought it or what brand? Quote Link to post Share on other sites
the hot tuna Posted August 31, 2009 Report Share Posted August 31, 2009 I asked earlier about this and no there is no alternative as far as upper and lower receivers yet because of the weird brass sleeve in the buffer tube. Quote Link to post Share on other sites
Raven1 Posted August 31, 2009 Report Share Posted August 31, 2009 (edited) Awesome! I will keep in touch. Oh and one other thing, are we related??? I've had the M6A2 in my online shopping cart for the past two weeks now for when I get back. Good *suitcase* man! Where the hell did you get the MS2 sling and the B.A.D.??? Lets just say I had a good 'Buddy' who gives me heads up everytime something is about to drop! So apparently FaceBook IS Good for Some Things! MS2 Sling and the A.S.A.P. Plate were bought off the Magpul website about 12 minutes after they showed up. Heads up to the rest of the peoples who are able to buy Magpul items. They update their site either Monday or Fridays at 5 PM Mountain Time ONLY! So Now You Know! As far as being related, can't so no or yes as my daddy was a big ol player,,, Edited August 31, 2009 by Raven1 Quote Link to post Share on other sites
Raven1 Posted August 31, 2009 Report Share Posted August 31, 2009 (edited) Raven1 did you get a extra plug and spring in the package like Donut did. Maybe that is why you are having the bolt locking issues. I Did NOT receive the extra parts like Donut did! This Might be why I am having the bolt locking issue, for the moment I am using some wiring insulation to give the bolt stop a slightly larger outside diameter and the bolt is locking back for the moment. But I would prefer to have a 100% factory original gun with no modifications when it comes to the BB processing department,,, Edited August 31, 2009 by Raven1 Quote Link to post Share on other sites

Raven, yours seems to be Magpulled out, including the receiver. May I ask, if not already stated, where you bought it or what brand? No body kits as of yet, but the gun has been out for nearly 2 months. Even on the AEG side of the house it is normally about 6 - 8 months before all the after market goodies show up.

Isamu Posted August 31, 2009 Report Share Posted August 31, 2009 I agree, those mags may perform awesome, but for me they are a "no no", I prefer STANAG mags, short or long and with more capacity, not 130rds but 70. Real caps are too real for me Never thought a Gas rifle could be so reliable, but thanks for showing us this is, Raven1 Quote Link to post Share on other sites
Kai_Wolf Posted August 31, 2009 Report Share Posted August 31, 2009 Thanks for the reply Raven. I did have another question as I am not too familure with Rail systems for the gas rifles. Would I be forced to buy a DD rail that is compatible with WA? Or will the cheaper chinese made ones fit? I guess that question extends for any rail system. Will most kinds fit?

I guess that question extends for any rail system. Will most kinds fit? No you are not forced to go with WA only front sets. Fun Fact: AEG, WA, AGM, G&P All Use MILSPEC Barrel Nuts. Again, any front end rail system that fits these units will fit your KJW M4. The cheaper Chinese rails will fit, how ever the top rail of the cheaper units May NOT match up perfectly in height with your upper receiver! If that is not an issue with you then you have more than enough options for you to fit your needs and most importantly - Your Budget! Quote Link to post Share on other sites
BrooklynBorn Posted August 31, 2009 Report Share Posted August 31, 2009 Let me clarify, You can use AEG rails, handguards, outer barrels, ets, on the KJW? Quote Link to post Share on other sites
Raven1 Posted August 31, 2009 Report Share Posted August 31, 2009 Let me clarify, You can use AEG rails, handguards, outer barrels, ets, on the KJW? AEG Rails, Hand Guards, etc, Yes. Please refer to post # 148 on page 8. The standard AEG barrel needs to machined cut to work on the KJW M4. Which is what t_hum machined off of the underside of the barrel as it fastens to the upper receiver. This is so the BB extractor on the BCG doesn't slam into the outer barrel. And to the bore of the barrel needs to be drilled / mill cut down slightly so the inner barrel / hop up bucking housing will sit properly in the bore of the outer barrel so the hop up adjuster will contact properly providing the adjustment. t_hum performed those cuts with a CNC Milling machine and it took about 30 minutes. I provided the dimensions in that post so the barrel can be cut cleanly and accurately. But essentially it is an AEG barrel with 2 more small cuts - not difficult at all to manufacture.

enjoi74 Posted August 31, 2009 Report Share Posted August 31, 2009 Intrudershop has a M4A1 Steel Front kit for KJ GBB/MARUI AEG. It already has the cuts. It costs $210, but it's steel. Check it out. http://www.intrudershop.com.tw/show_produc...roduct=1361#top Quote Link to post Share on other sites
t_hum Posted August 31, 2009 Report Share Posted August 31, 2009 (edited) Honestly, the modifications I made to the barrel could have been done with a lot less precise machinery. A drill, two drill bits, jewlers file set and a small coping saw could have gotten the job done, albeit a lot uglier than with the mill. We went with the mill because its almost a guarantee it will come out right as opposed to flying by the seat of your pants. The cut on the underside of the barrel can be quite oversized as by the time the loading nozzle is occupying this area the bb is already chambered. The removal of material from the ID of the barrel to accomodate the hop up chamber is a little tricker though, especially with split point drill bits as opposed to an end mill. This cut should be done with extreme caution and a lot of patience. .079" is really small getting it just right is tricky. The best thing to do is have a few orings on hand that will fit over the barrel in front of the hop in case you go too deep. If anyone gets to the point where they want to do this and wants detailed instructions and measurements feel free to contact me via PM. 210 bucks for a steel front set is rediculous. A steel barrel can be found for 60 or so dollars all over the place and the other misc parts are not too much either. The cuts are not worth 120 bucks. Heck, for a 120 dollars Ill do the cuts for any takers . Edited August 31, 2009 by t_hum Quote Link to post Share on other sites
enjoi74 Posted August 31, 2009 Report Share Posted August 31, 2009 It's really for people that don't know how to do it or don't have the tools to do it. If they have the money and don't have the time to miss with it, then they gata do what they have to do. Or they can pay you to do it. Quote Link to post Share on other sites

Check it out. http://www.intrudershop.com.tw/show_produc...roduct=1361#top Yeah - Ouch! A bit pricey for an AEG / GBB Barrel, just for data gathering purposes and information sharing. A standard AR-15 Barrel that is made to withstand SAMI Spec pressures - roughly 54,000 PSI - manufactured to MILSPEC is around or less than $200. Here are some examples, http://www.del-ton.com/AR_15_Barrels_s/3.htm http://www.brownells.com/.aspx/cid=778/k=a...ll/search=ar-15 The point is there are some quality barrels some of which are chrome lined for less than or around $200 and depending on the process will go considerably higher in price point. A GBB / AEG Outer Barrel Does Not Need To Be Hardened / Chrome Lined! The Inner Barrel Is What Sees The Pressure From The Propulsion Gases! NOT The Outer Barrel. Look guys, after market support for this gun is already on the way with barely 2 months out in production. Which is a lock that ACM Manufacturers will soon be releasing their attractively priced products as well. With Only 2 additional cuts needed who is to say that from now or some point in the future some or most AEG barrels will have these incorporated in order to move more product. As much as some people in the other 'Camps' say this isn't going to happen. Well,,, It IS Already Happening. So lets just sit tight and watch things unfold as at the moment it could go either way. One thing is for sure, Competition IS A Good Thing - Keeps Prices Down - More Choices For The Consumer. Thus Far my conclusions of the KJW M4 is below (Keep In Mind My Testing Is 30% Completed) AEG Reliability - 14 mags right out of the box, wear is minimal to non existent, all hardened / quality metal components / no need to install reliability upgrades to function, in short the gun functions as expected right out of the box. AEG Gun Pricing - At $300 the gun is right on par with a quality AEG with comparable components, the fact that the gun needs no other modifications to run and keep running makes the $300 price point a very good value. AEG Accessorie Pricing - All AEG stocks, front sets, sights, optics mount on this gun. Which Is Huge, most who have been air ballin for some time will have these accessories on hand. Adding value to the KJW M4 Weapons Platform. Gas Blow Back Design - Based on Koba-san's tried and tested GBB Pistol design. The design has been in use, tested, perfected and proven over an 11 year period of time. It Is A Mature Product line that is designed for function and reliability. The Tanio Koba Design Is Not Meant To Replicate the Legacy AR-15 Direct Gas Impingement Design which the WA Clearly is doing. The Tanio Koba Design Isn't Trying To Be Another WA Clone It Is Something Entirely Different. It is said that you should "Lead, Follow or get out of the way." KJW clearly chose to go their own way,,, In Summary - The KJW M4 is reliable, consistent shooting gas blow back rifle! It Is Not the WA M4 and clearly was not intended to be. The WA Design mimics closely the legacy AR-15 Direct impingement design. If that is what one is wanting / looking for then that option is available. We all know the characteristics and operational record of the WA Design - There Is No Disputing the Facts - It Is What It Is. If Right Out Of The Box AEG Reliability Is Priority One? If Value and Not Needing To Up Grade To Keep The Gun In The Fight Is Attractive? If All Metal Body, All High Quality Metal Internal Components Are Prerequisite? If Reasonably Priced - Well Designed Magazines Are Mission Essential? If Setting The Hop Up Adjustment Is Just Set and Forget? If Cross Platform Inter-Changeability / Ability To Use Most Existing AEG / WA Accessories Is Available? If Being On The Field And Skirmishing All Day For No Other Reason Than Simply Because You Want To. Gentlemen These Questions Have Been Answered - This Gun Is For You,,, Quote Link to post Share on other sites

Raven1 Posted September 1, 2009 Report Share Posted September 1, 2009 So... why are we talking about RS barrels now? For Price Comparison Only! That barrel in the link seems to be priced much too high for an outer barrel. The MILSPEC barrel pricing was used to make my point, or so I thought,,, Quote Link to post Share on other sites

Raven1 Posted September 1, 2009 Report Share Posted September 1, 2009 and... why can't we just use aeg barrels? since they work, and there are a lot of high quality aeg outer barrels... Exactly my point, if high quality MILSPEC Barrels can be produced affordable - there is no reason why an Airsoft outer barrel can't be produced affordable as well. My point is $210 for an airsoft outer barrel is a bit too much,,, Quote Link to post Share on other sites
