Andrew12 Posted September 9, 2010 Report Share Posted September 9, 2010 (edited) Guys I plan to use silicon oil on the seals but for metal on metal parts of the mechanism I feel I'd be better off with a molly grease or possibly even copper grease as I find the silicon grease to be quite gummy at lower temps. What are folks opinions on this? There are only two places you should be applying ANY lube. The piston cup and the buffer tube. Both need only a light coating. This gun handles best with 100% silicone grease with PTFE in it. This is the stuff we use over here: Edited September 9, 2010 by Andrew12 1 Quote Link to post Share on other sites
weekenny Posted September 9, 2010 Report Share Posted September 9, 2010 I'll have a look for something similar over here. I must say I'm surprised the hammer, sears, trigger, bolt stop etc none of these moving parts get any grease? I realise on a real AR that would likely see a load of grit and sand in its life then its not a good idea to have grease on there but I'll bet the real ones are better built.

ziofester-asaf Posted September 9, 2010 Report Share Posted September 9, 2010 (edited) wow... we started so well....LOL today my new&virgin KJW, badly freezed at half of the second magazine and started to spit everywhere... nice Edited September 9, 2010 by ziofester-asaf Quote Link to post Share on other sites
t_hum Posted September 9, 2010 Report Share Posted September 9, 2010 What were you doing when it happened? Did you do two magazines full auto back to back? Ive seen frost and ice form on the inside of the bolt cup from heavy full auto use. Quote Link to post Share on other sites
weekenny Posted September 9, 2010 Report Share Posted September 9, 2010 (edited) It arrived, CASV front set, Magpul stock, Magpul AFG fitted almost instantly lol. Just waiting on Cradle parts to arrive as its doing 440 at the moment on Green. (ignore the rear sight waiting to try a MBUS for fit). Quick question on the hop (can't range test it here) looking down the barrel I cant see much movement from the hop rubber, how obvious should the 'bump' be?

I would rather pay a few bucks more and know my stuff isn't going to get held up or seized in customs. Quote Link to post Share on other sites
PapayaSalad Posted September 10, 2010 Report Share Posted September 10, 2010 My plastic upper is at the post office(wasn't home). Going to get it tomorrow morning and try to find my camera. Quote Link to post Share on other sites

I emailed them when it said their KJW m4 mags were "in stock" and they informed me that they were in fact not in stock. Airsplat.com sucks when it comes to that kind of stuff.

I'm talking about the gun, not the mags. The mags are back in stock all over every week or so, just need to grab them when you can. I'll be trying to import some mags here shortly, but its tough, even KJ can't keep up. Make sure to take some pics of the plastic upper. How much was it shipped?

ahadsz Posted September 10, 2010 Report Share Posted September 10, 2010 so yeah any upgrades out of the box needed? Or keep it stock? Quote Link to post Share on other sites
Andrew12 Posted September 10, 2010 Report Share Posted September 10, 2010 so yeah any upgrades out of the box needed? Or keep it stock? I would grab a piston, velocity reducer and carrier extension from cradle airsoft. All that will run you about $65. it doesn't hurt to grab some spare parts like the bands and piston cups, #35 springs from kjw. Quote Link to post Share on other sites
DRAGON64 Posted September 10, 2010 Report Share Posted September 10, 2010 (edited) so yeah any upgrades out of the box needed? Or keep it stock? None needed out of the box, the rifle was quite usable when I owned one. Cradle sells some great upgrades. In my opinion, the one upgrade I would do first is the BCG extension to help protect the lower receiver buffer tube stop. The buffer piston might hit the stop hard enough to break the lower receiver... This has been confirmed on a number of rifles in this thread.

Just so everyone knows, the latest batches have had the back(buffer side) of the buffer stop/retainer ground down to prevent this. Quote Link to post Share on other sites

I understand you are talking about the guns, I am just letting the "question asker" know that he should contact airsplat before making an order with them because they do not update their stock regularly. Also, I had to dremel my own buffer lock. It didn't come stock from the factory "ground down". It isn't a hard job at all, but it doesn't come already done either. Mine is a CQBR as well and is less than 2 months old. Edited September 10, 2010 by nickthebrick65 Quote Link to post Share on other sites

Hope we are talking about the same thing...Raven1 and I took mine down after I got it three weeks ago and He said it was already done enough not to bother. I have seen him grind down one before, it was more vast than the stock one, but it looks to be about 2-3mm worth off the back of the buffer retainer Quote Link to post Share on other sites

Cool that your's was already done though. Indeed. Mine came from a batch at Airsplat. Where did yours come from? Airsplat has been continuing to buy the large batches from KJW. When speaking with their purchasing people they expressed they are currently awaiting a large shipment of mags and will price them very well. Quote Link to post Share on other sites
ahadsz Posted September 10, 2010 Report Share Posted September 10, 2010 Well im getting the cqb, from ehobby can you guys link the parts for me? I cant seem to find any kjw rifle spare parts or upgraded parts? And how is the one from ra-tech is that good as well? Quote Link to post Share on other sites
sandstorm Posted September 10, 2010 Report Share Posted September 10, 2010 Cradle Airsoft has their own website, don't know if any webstores have gotten his parts. He's also here in this thread as T_hum, he and Raven1 are the go-to guys for endurance-testing and fixing the KJW M4. Quote Link to post Share on other sites

I cant seem to find any kjw rifle spare parts or upgraded parts? And how is the one from ra-tech is that good as well? Why? You are going to pay over $400, so unless you are ordering mags with it..Airsplat has them for $399, use the code "returncustomer" and you will get 5% off, that is $379 plus $12 shipping, that is still less...I would recommend it.

weekenny Posted September 10, 2010 Report Share Posted September 10, 2010 Well I've had a closer look at mine today and the small area removed from the buffer lock can only be seen when you know what to look for. I missed it on my first look. Since I'd already ordered the carrier extension I'll fit it anyways. Quote Link to post Share on other sites
ahadsz Posted September 10, 2010 Report Share Posted September 10, 2010 im getting mags as well, and I trust ehobby compared to airsplat, i heard there really bad even worse then evike. Quote Link to post Share on other sites
t_hum Posted September 10, 2010 Report Share Posted September 10, 2010 (edited) The only sure way to tell if you need a carrier extension is to observe the fit between the buffer and bolt carrier as you shut the receiver. As the receiver pivots downwards the bolt carrier should contact the buffer at about 25 degrees from closed and begin to push the buffer into the buffer tube as you continue to close the receivers. If its not hitting at all or it doesnt touch until its nearly closed the buffer is not sitting far enough back. Ive never seen one of these reshaped buffer detents. If it is ground down the back surface should be about .050" offset. More is fine, less is bad. If you have one of these detents the above check does not apply.
