I have 24 mags and I too have experienced feeding problems with some.
I have found that some mags lack spring tension which translates into the mags inability to feed bb's properly.

Simple fix:
- Completely disassemble mag and stretch the internal spring ever-so-slightly.There are two springs inside so make sure you stretch both.
- Do not over do it or you will have one hell of a time getting it back inside and you could also cause more trouble as well!
- Apply a little silicon oil to the two tiny springs on either side of the mag follower.
- Reassemble and test.

If you need a schematic to reassemble the mag have a look here:

I have fixed four mags so far to date this way and they have never acted up since the repairs!

Good luck!

Getting the mags back together is comparable to licking horse asshole.

One way to get it in is to screw in the bottom 2 screws on yer mag's spring housing... that way the spring wont fly out, and hit ya in the eye every 2 seconds. >_O;

I may have something to offer on the whole shattered BB thing.

I was loading my PTW using the correct loading rod and I have noticed the first batch of BBs go in okay. The second batch however are a BUGGER - you really have to reef down to get those BBs in - so much so that I think its possible to deform the BBs while loading them. If they get deformed, it would explain both the report of BB shavings and of shattered BBs.

So I think its probably the mag and the loading process that may be compromising BBs and not the actual firing process.

A buddy got a PTW the other day, and phoned me all in a panic when he saw a BB shatter on him. I let him try one of my mags with Metal Tech BBs, and the gun ran fine, no breaks. His mags were filthy with dirt, sand, grass, etc.

Once we cleaned one of his mags out, and tried his BBs, breaks were fewer, but still occuring. He was using Madbull 0.25g BBs, and when we tried the Metal Tech in his mag, it ran fine the whole mag.

So, I decided to do a crush test on the Madbull BBs. When I crushed it to an easy stop with the pliers, the Madbull split in 3 or 4 areas, and the BB was deformed to 4.02 mm. The Metal Tech when tested split once only, but deformed to only 5.10 mm. The Madbull made a little "POP" sound when crushed, while the Metal Tech was virtually silent.

I would not recommend Madbull for a PTW, or any other gun with a steel nozzle or chamber.

i would definatly agree there, i stopped double loading them due to this worry. i only fill them with on tube full.

I've not tested metal tech brand bbs yet, but I have found that bb bastard brand runs awesome, no chopping in .2, .25 and .28g weights.

Kokanee - do you double or single load?

I used .30 BBs this weekend and when my gun wasn't failing due to moisture, I had no problems.

Has anyone run any comparison tests of Bastard .28 vs. .30s in a PTW? I am tempted but would like to hear what others have seen? Worth it? I felt a good improvement between .25 and .28's so interestied to hear .28 to .30s

My PTW is on its journey to failure. The 490 motor sounds like its about to go really soon. Sounds a bit like this "Grrrrrck" on every fire. It fires fine now though.

The PTW is a late 2007 M4a1 with that ball bearing installed at the bottom of the motor. I removed it as soon as i read it on here.

Also i had another problem with my blue cylinder and my FPS was so low, it was firing at 270fps. Thanks to Mcguyver, the problem was the position of that locking mechanism for the cylinder and the top reciever. I had it so i could remove the top cylinder with ease. I suppose it wasn't air tight so it leaked.

if anyone is selling a gold cylinder (used) let me know!

If it's rated to charge a 9.6v battery, and can do it such that the pack does not get hot or even warm, then it should be fine.

I use an MRC Superbrain 989 charger, but I also use 12v batteries (1200 and 2400mah) and use the discharge function. My batteries never heat up (as I can control charge and discharge rates with good precision), and even after a year of use, my 1600 mah batteries take 1905 mah on charge each, within a few mah of each other.

But my charger is about $200, the one you posted above is about $40. In the end, what is a better charger for $100 batteries? You have to decide that for yourself. A rule of thumb I follow is your charger should cost the same as 1 battery at least, with cost being an indicator (sadly not always so) of quality.

I have one as well, it gets the job done fine it seems so far. I only wish it had a display to tell me how much mah I getting into each battery and maybe have a discharge built into it. Right now I have just a TM led discharger that takes like 4 hrs to discharge the battery which sucks on a Friday night getting ready for the Saturday game but again it works so no major complaints

i tried the mag repair and doesnt seem to have done a whole lot, i stretched them more than just a little. but heres my other question, i see there are two springs in there, seeing as i dont double load them, if i took out the first spring and put filler in place of the second spring, this would not only resolve the jamming/ loading issues but would make it a low cap, anyone done this or have any comments?
