This post may releive just how much I need to learn so if it comes ovr as stupid please forgive this fng

I recently acquired a KA Thompson M1A1 and have had all kinds of trouble with it miss feeding. After asking a friend who knows about these things to have a look he stripped it down, had a shufti and declared it fine, but once I got it back had the same issues again. Having tried a few different things (changed the mag to one I know works, changed the battery, changed both) it was still miss-feeding. In desperation I tried changing from 0.2g BBs to 0.25g and it seems to feed much better (semi-auto now works, full auto not so much).....sooooo my question is has anyone else had these sorts of issues, and do people feel moving to .28 or .3g might be the best move?

Thanks

the problem might not be so much in the weight of the bb's more in the quality / brand. which brand are you using? i ask as for example my ICS M3 jams on Zero one brand bb's but runs perfectly on Gunfire brand rounds.

i'd put my money on the BB's as well ,i never use anything but excel or blaster .as for zero one BB's ....well some of them are round in shape but not many and once you use a decent barrel like in the king arms guns then you have no hope at all .

Give me a big enough hammer and a place to stand and I could fix the world.
i'll kill a man in a fair fight or if i think he's going to start a fair fight or over a woman or.......
a problem shared is a problem halved ,but an advantage shared is no advantage at all
if a job's not worth doing then its certainly not worth doing well

Best description ever.

I once encountered cheap BB's that were so coarse, that once fed into a mid-cap magazine, they refused to come out - the BB's were simply too coarse to slide against each other inside the mid-cap and feed up/out as the top ones were fired. I still shudder to think what they did to my hop-up rubbers.

Ok interesting, no idea what my 0.2g are but the "better" ones were Blaster Devils. Any other brands worth trying?

Goldenball's always work great for me

I would agree with some of the other forum members ... the probolem is your balls!

Golden balls are the bottom tier balls for AEG's
Blasters are Mid Tier ok in most guns. Some tightbores on full auto have issues.
BB Devils are high Tier. You could include Excels, Marui BB's. King Arms / Swiss Plantinum Series I have used a lot lately and never had an issue they are to a 0.01 tolerence +/-.

Certain shops will sell your own, avoid like the plague. The exception might be Red Wolf high grade series although have not tested these myself.

Why do you say goldenball's are bottom tier? Just asking as I have a lot of them to get through and don't want to jam up my gun if I can help it.

They are graded as such by the manufacturer.

I saw a video, I think on popularairsoft.com about them. They are made cheaper and are meant to be sold cheaper than the other two. Fine in moscarts and the such and possibly guns with stock barrels but would not recommend them. BUT If you have had no issues so far, then carry on using them! :good: But if you tinkered with your gun by adding a tightbore barrel have another type off BB's at hand just in case.

Ah, I do have some tightbores. Might swap it out for the stock barrel until I use the goldenballs up.

Had same issue a long while back. it was the bb's. i ran out of bb's at a shoot so i bought some on site. they were some brand i never heard of but the misfeed. i went back to blasters and everything was perfect. As above i don't trust anything other than blaster, excel or madbul.

Has anyone used the BAW bb's as sold by Airsoftworld? They seem a very decent price but are they as good as what people say on the feedback? Enqiring mind wants to know :shock:

The ones my girlfriend got a while ago were not bad at all, they all seemed smooth and well polished. No mold lines in sight.

I may have had some of these a while ago but not sure as my memory is shit :rofl: . If so I can't remember having any issues with them if I did get some and given their price its worth a punt I suppose.
