Sallinen Posted December 7, 2012 Report Share Posted December 7, 2012 (edited) So I received 2 of the said items today. External quality of the magazine is rather good. The opening for the bulb on the magazine is quite big, I am afraid it could in theory get knocked off of its place with enough force. BB spring is stronger than that of in my old style co2 magazine. The co2 bulb piercing end seal is NAILON!! I wasted a whole co2 bulb because it didnt seal it pretty much at all. I am currently working to fix this. I tried to put a o-ring of smaller size between co2 bulb and nailon seal, which worked otherwise perfectly(no hiss when capsule was thightened in the magazine), but didnt allow the pin to pierce the bulb properly which resulted in poor performance. I am going try tomorrow a thinner o-ring solution, which should work. Other thing to mention is that the magazines co2 bulb alignment differs a little from that of in my KJW MEU. The bulb is a bit more towrds the forward of the muzzle end than the opening for it in the gun. This doesnt show up at all when inserting magazine, but requires pulling motion to get the magazine out of the gun. Probably fixable by simply sanding the magwell a little. Will get pics and more proper info tomorrow. Opinion of these so far: A little dissappointed that the seal is nailon, but IF I can get these to work fine, I would be perfectly happy with these.

Algy Posted December 8, 2012 Report Share Posted December 8, 2012 Sorry to hear that the new magazines are not much of an improvement. But at least they look a bit better than the large base plate ones. Instead of using an o-ring between the nylon seal and CO2 bulb, I use PTFE tape (plumber's tape, Teflon tape or whatever you call it): Just wrap some around the top of the bulb. It's soft, so forms a pretty good seal. Good luck getting the mags to work. Quote Link to post Share on other sites
Sallinen Posted December 8, 2012 Author Report Share Posted December 8, 2012 M'thinks that ptfe tape in this case could be too soft. I managed to find a good sized o-ring, which turned out to work well. The o-ring size that worked for me: 8mm OD, 6mm ID and 1mm in thickness. Needs just a tad bit of force to get the bulb pierced well. I think these will actually turn out good, just add that o-ring and the mags should be perfect after that.

blobface Posted December 13, 2012 Report Share Posted December 13, 2012 Perhaps buy an RA-Tech co2 valve for KJ co2 mags? Should be compatible? They have it in stock in Airsofttaiwan, I got a few but I still haven't installed them. Quote Link to post Share on other sites
Sallinen Posted December 14, 2012 Author Report Share Posted December 14, 2012 I will have to try one of those some day. At the moment the mags are working fine but the o-ring is loose and changing bulbs is a little bothersome. Quote Link to post Share on other sites
Wingmann Posted December 15, 2012 Report Share Posted December 15, 2012 (edited) I put a capsule in one of mines on Wed. I just (Sat. morning) shot two mags worth to test the new nineball rubber I installed and at the last shot it still felt plenty strong No problem with the nylon base so far...

Sallinen Posted March 3, 2013 Author Report Share Posted March 3, 2013 These mags work great. I had forgotten one magazine with a full capsule in it a little after I made this topic. Now I remembered it and found it to be in full state and shot the magazine empty. It had been with me on the few winter games I have played this winter as filling for a mag puch.

Isamu Posted March 3, 2013 Report Share Posted March 3, 2013 I wrote KJW about if these were going to be bundled with their 1911 and they confirmed it, so good news for everyone. Quote Link to post Share on other sites
Horsem4n Posted March 4, 2013 Report Share Posted March 4, 2013 why do you guys have so many issues with nylon seals? KWC uses them all the time and i never have issues. 1 Quote Link to post Share on other sites
Wingmann Posted March 4, 2013 Report Share Posted March 4, 2013 AFAIK only Sallinen doubted them. I left one of mines with a full CO2 capsule in almost two months ago. It's still holding. 1 Quote Link to post Share on other sites
Sallinen Posted March 4, 2013 Author Report Share Posted March 4, 2013 I dont know what I did with my magazine when installing the bulb but I wasted a complete capsule. After that I have just kept the o-rings in there and since then there has been 0 leaks from bulb end. Quote Link to post Share on other sites
Kratisto Posted March 12, 2013 Report Share Posted March 12, 2013 (edited) So, how are your mags holding up? They use the same valve with a short life span than the older ones or a new one more durable? Edited March 12, 2013 by Kratisto Quote Link to post Share on other sites
Sallinen Posted March 14, 2013 Author Report Share Posted March 14, 2013 Well havent used them in a game since the last post. Will go play next saturday and I'll report back if there is any change to their state. I still have the one mag with co2 bulb in it that I forgot in my rig, shot a few times and no hissing as of yet. Tried to remove the valve with a flat head, material is too soft and the valve is too tightly on. Quote Link to post Share on other sites
Kratisto Posted March 15, 2013 Report Share Posted March 15, 2013 Thanks Sallinen, let's hope that the valve inside is not the same as the older mags... Quote Link to post Share on other sites
Sallinen Posted April 7, 2013 Author Report Share Posted April 7, 2013 Finally managed to play a game. Temperature was about +0 to +5 celsius. In total the gun KJW MEU shot 2 full magazines with no hicups until the very last few BBs. The gun did swim in snow between shots etc. Quote Link to post Share on other sites
Lancaster Posted April 14, 2013 Report Share Posted April 14, 2013 and they seems to be unavailable anymore anywhere... Quote Link to post Share on other sites
Wepeel Posted April 15, 2013 Report Share Posted April 15, 2013 Are leaking issues fixed with these new mags? They also seem to still be out of stock everywhere I look. Quote Link to post Share on other sites
Wingmann Posted April 15, 2013 Report Share Posted April 15, 2013 One of mines still has the first bulb in it. I shoot it sometimes and it's got pressure after all these days. 1 Quote Link to post Share on other sites
Algy Posted April 15, 2013 Report Share Posted April 15, 2013 Is it wise to leave a bulb screwed into the magazine? I was told that one should always leave them empty for storage. 1 Quote Link to post Share on other sites
Sallinen Posted April 18, 2013 Author Report Share Posted April 18, 2013 I guess its not but my mags are still perfect with zero leaks, though I do still use the o-rings on the bulb piercing cap connection. Played indoors with these mags. With my somewhat upgraded MEU they shot every BB until the last one which was a sphhh, no sluggish shots, just the last one which used the last Co2 left in the magazine.

Algy Posted January 16, 2014 Report Share Posted January 16, 2014 My old style Co2 mags are having great difficulty firing more than 16-17 shots in current temperatures (it is rather chilly, but that's the point of using Co2 mags), and was looking at these as a permanent replacement. So what is the verdict on these? Is it functionally better than its chunky predecessor, or does it just look more appealing? Apologies for the dreadful necro. Quote Link to post Share on other sites
Wingmann Posted January 16, 2014 Report Share Posted January 16, 2014 They work definitely better, but one of mines has developed a leak at the nylon cap. I have yet to solve it as Sallinen did. Quote Link to post Share on other sites
Lone_Bullet Posted January 17, 2014 Report Share Posted January 17, 2014 (edited) I had one mag out of 5 which kept leaking to the point that the whole mag was covered in ice. Keep in mind, I have all my mags 3 years+ now, they're all old style mags. Don't skirm thàt much, but i do store my mags with the capsule in the mag. I thought that leaky mag was a goner till I studied the structure a bit better and tried to turn the piercing cap with a HUGE flathead screwdriver. And... well.. I fixed it. It was loose, as in REALLY loose. Now all my mags work perfectly. What I do is grease all o-rings / rubbers with Guarder silicone grease and I've added a Lee precision mag shim for a tighter fit. Every ... say 3-4 months, no problems. Edited January 17, 2014 by Lone_Bullet Quote Link to post Share on other sites
Sallinen Posted January 19, 2014 Author Report Share Posted January 19, 2014 Still rocking the o-rings on the nylon seal, with them zero leaks, other mag has had a bulb in it it for 2 months now and still all gas left. Quote Link to post Share on other sites
Finbarqs Posted February 13, 2014 Report Share Posted February 13, 2014 where do you get these mags? Quote Link to post Share on other sites
