Marlowe Posted August 11, 2005 Report Share Posted August 11, 2005 These things look very nice. I wouldn't swap my RPK for one, but I would certainly prefer one over the usual SG1 / Armalite & C-mag "support" variants that rear their ugly heads... Link to post Share on other sites
Catchv22 Posted August 11, 2005 Report Share Posted August 11, 2005 Looks a bit bulky for righties. Link to post Share on other sites
Yance Posted August 12, 2005 Report Share Posted August 12, 2005 I found some interesting info for us to discuss. 1. I finally know the problem with the batteries placement. The stock is designed to fit 9,6v batteries. Even if the measurement different between 9,6v and 8,4v batteries is just the lenght not the width, 8,4 batteries wont do. I think it's because the bulky single battery that stick in the end of the set. When I put my 9,6v it fit perfectly, and like every one said NO MOD NEEDED. Just need to fix some wire in order to put the stock butt. The problem is, is it ok to put 9,6v batteries to unupgraded stock AEG ? Isn't it be safer just to put regular 8,4 batteries ? Please advise 2. One of my friend also got his piston and gears stripped after few hundred rounds. I somehow think that maybe he does not read this m249. I turn off the hop up and have no problem with stripped gears and piston at all. Maybe it's not the GEARBOX but the feeding mechanism that stripped the gears. Comment anyone ?

Wehrmacht54 Posted August 12, 2005 Report Share Posted August 12, 2005 No the reason most Aegs like Tokyo Marui and ICS come with PLASTIC bushings, so if you put a 9.6v in them the bushings would melt. But Classic Army does BEARING gearboxes which are metal. So they are preupgraded to use 9.6v batteries. Example, I just bought a Classic Army M15A4 Cqb/r and it uses a 3300 MAH 9.6v battery no problem. Link to post Share on other sites
Yance Posted August 12, 2005 Report Share Posted August 12, 2005 So you said that for all CLASSIC ARMY AEG it's ok to put 9,6 and for others (MARUI, ICS,etc) use 8,4. What about the stripped gear problem ? Is it just some random malfunction or is it because the hop up system mentioned before ? Link to post Share on other sites
Wehrmacht54 Posted August 12, 2005 Report Share Posted August 12, 2005 Stripped gear is definatly the hop-up problem. I saw sign posted at my local Airsoft store talking all about the hop up problem...basically DONT adjust it too high or else its gonna strip the piston. Other than that a 9.6v battery has no problems being used in any of the Classic Army guns. And Marui and ICS use 8.4v until you upgrade the bushings to metal, then your good.

Hissing_Sid Posted August 12, 2005 Report Share Posted August 12, 2005 Why on earth did CA actually BUILD the hop-up so it can be screwed in enough to stop BBs firing??????? Link to post Share on other sites
Trasher Posted August 12, 2005 Report Share Posted August 12, 2005 Use a little common sense and you probably won't strip piston with the hop-up. I think it's simple as that. Show me an AEG which is foolproof... Link to post Share on other sites
Catchv22 Posted August 12, 2005 Report Share Posted August 12, 2005 Different power levels and rates of fire will affect how easily a BB can get past a hop up. Not everyone's limited to 328 fps you know. Or they're just lazy and cheap. Link to post Share on other sites
Screwschom Posted August 12, 2005 Author Report Share Posted August 12, 2005 A hop up that can be adjusted too much is better than one that does not adjust enough in my book. A hop up with a wide variety of setting for different power out puts is prime. What happenes when the bb's jam is the nozzle gets jammed back and then one of the gears strips, usually the sector gear from what I have seen. On the 249 the piston seems to go. Hey, has anyone had the problem of bb's collecting inside you gun, like down in the handguards and magazine well. Twice I have had problems under fire tring to get the box mag do-hickey into the mag well, but the connection was impeded by bb's floating around in the magzine well. I have finally learned to decompress the spring tension of the box mag and then insert the do-hickey into the well. 249 Tech: If you ever take off your outter barrel and then the inner barrel comes out you will see a spring on the inner barrel keeping lateral pressure on the hop up unit so it seals with the mech box. If you loose this spring your gun will not feed. A easy replacement spring is a cut down AEG spring, it does the trick and the added tension helps IMO. Link to post Share on other sites
Trasher Posted August 12, 2005 Report Share Posted August 12, 2005 Hey, has anyone had the problem of bb's collecting inside you gun, like down in the handguards and magazine well. Yep, I am installing a shield inside the magazine well... I did the same to the boxmag, so I can load faster from the side. Link to post Share on other sites
Hissing_Sid Posted August 12, 2005 Report Share Posted August 12, 2005 Hang on a second... I don't know much about the CA249 gearbox but anyway... If the hop-up was to jam full of BBs then the nozzle would jam in the rearward position. This should mean that the tappet plate is forced into it's rearward position. The Sector gear should be able to whizz around and round while barely touching the tappet plate as it goes wrong. Assuming the CA249 gearbox works the same as any other AEG gearbox then BBs jamming in the hop-up should NOT cause damage to the gears. Link to post Share on other sites
keyserSOZE Posted August 12, 2005 Report Share Posted August 12, 2005 i think the problem is caused by the tappet plate. from what i can see happening, bbs get jammed in the hopup chamber. a bb then will seat itself right up against the nozzle. as the spring decompresses and the piston moves forward, air is pushed forward and out the nozzle. but since a bb is jammed up against the nozzle and no place to go, there might be too much air resistance/pressure for the piston to go forward completely before the next cycle. then the sector gear wont line up with the piston's gears.

Trasher Posted August 13, 2005 Report Share Posted August 13, 2005 Today, I finished the first woodland skirmish with mixed feelings. On the positive side, me and my mates fired around 3000-3500 rounds from the boxmag with zero feeding probems. The ROF and the "wall of BBs" effect was excellent, the CA249 is a great (and intimidating) support weapon. Kneeling, shouldered position worked the best for me. But here is the downside, 1. The outer barrel came loose numerous times (I gonna fix it to the receiver with a screw, who needs the quick release lever anyway) 2. Opening and closing the bipod is PITA, it requires both hands when the legs are extended, plus it scratches the boxmag (a camo cover and the installation of a real steel bipod can solve that. Getting rid of the bipod and installing a RAS w/ vertical forgrip is also considered.) 3. I have to reroute the boxmag switch to the forearm for easier access. In the heat of the battle it's hard to find the button (especially with gloves). 4. After a couple thousand BBs (I fired short burst mostly) the gun started firing from itself! It went into "autopilot mode" and sprayed BBs whenever he wanted with the safety on!! I guess this is some kinda failure with the electrical contacts, but it's an annoying one! Any tips to solve the problem above? I don't have much experience with AEG-smithing. (Even with these problems the CA249 is a solid keeper.) Link to post Share on other sites

screamin_weasel Posted August 15, 2005 Report Share Posted August 15, 2005 has anybody had or heard of any problems with this gun? (yes i know its still quite new) me and my brother are 99% syre we are going to get one, but i just want any info available at the moment. Link to post Share on other sites

Is it just some random malfunction or is it because the hop up system mentioned before ? <{POST_SNAPBACK}> I replaced my gears with systema gears and use a deep fire piston wqith titanium teeth...

Phalanix Posted August 17, 2005 Report Share Posted August 17, 2005 Hey guys, if anyone's interested in a bit more reading. Here's a link to an Airsoft Canada thread where we've been discussing some issues of the CA249 as well. Link Link to post Share on other sites
GeneralPatton Posted August 18, 2005 Report Share Posted August 18, 2005 I've decided to wait for the Classic Army CA249P to come out and pick one up from AirsoftArms over in Ohio, as I told him to egrave my name in one of the 249Paratrooper Boxes Just gotta get the money first but I should have it this winter. I'm just a little nervous with all these peple saying their pistons get destroyed in like 1,000 rounds. Making me nervous to blow over $1,000 on a gun that may not work too great.

Trasher Posted August 19, 2005 Report Share Posted August 19, 2005 ZERO problem with the piston in 5K rounds... Where the real problem lies is the crappy stock microswitch. Link to post Share on other sites

Making me nervous to blow over $1,000 on a gun that may not work too great. <{POST_SNAPBACK}> Better than a gun that doesn't work at all, right? *coughTOPcough* An issue with the microswitch is that, make sure to have a barrel plug of some sort on at all times when in the safe zone. Someone can get hurt if the full auto starts going off by itself while in a safe area. Link to post Share on other sites

(yes i know its still quite new) me and my brother are 99% syre we are going to get one, but i just want any info available at the moment. <{POST_SNAPBACK}> CA might have solved that problem, but the CA249 I tried out made it very difficult to change M16/M4 magazines due to a too narrow mag well, I guess. That might not be an issue when used with a box mag, though. Link to post Share on other sites
Kristoffer Posted August 19, 2005 Report Share Posted August 19, 2005 The stripping of gears/pistons happen when a BB is jammed in the hop-up chamber. Basically, the system is so airtight that the gears grab the piston before the piston has completed the cycle. When this happens, the gears come to a point where the piston can't move further backwards, but the sector gear still has a few teeth that grabs the piston. The result is an awfull noice, and a stripped piston if you have prometheus gears, or stripped gears if you don't My prometheus gears have destroyed 6 Area 1000 polycarbon pistons, and 2 systema ALU pistons, and they don't have a scratch on them. Lovely little things they are It's the same problem I have had with my TOP minimi/PGC box. And the reason why I won't buy a CA 249 before I know for sure that CA has fixed the problem. I have seen CA249's strip after 200 shots. That isn't good... Link to post Share on other sites
GeneralPatton Posted August 20, 2005 Report Share Posted August 20, 2005 See now, this is why I probably won't buy the CA249 till late winter in early 06' so CA can hopefully find a solution to these problems (Shooting by itself and this piston problem). Hopefully by then they'll have it fixed. Link to post Share on other sites
