WE scar breaking bbs
 

Hi guys, my WE SCAR, when on full auto, break my bbs if I do more then small burst. The gun works perfectly on semi and the full auto with emptied mag works also, but if I fire on full auto more then 2-3 bbs, one bb will break in half and cause a jam: then I have to remove the magazine, remove the half broken bb in the magazine and in the gun (by cocking the lever). I m using Madbull high precision .30g bbs. Any ideas what is causing this, thank you

Do you have more than one mag...if so, does it happen with them all?

Happened to me on last shot. Do you have a clear lower by any chance?

I have only the magazine that came with it (propane) and it's not a clear lower, it's the original WE lower

Possibly just a bad batch of bbs. You have another fresh bag to try?
(best case scenario)

had the same problem with mine, full black version.

20's 25's 30's all broke and jammed. finally having no other bb options I put in some 12's and they went full auto no problem. I shot about 500 rounds through and when I reverted back to 25's no problems no jams.

some people have advised that the hop rubber needs some working in
and from my results I'd have to agree

Like a break in period?

i also have a we scar gbb that chops .25 and .30 bastards on full auto... happens with all 3 mags

So this is normal lol

imperfection of the gbbr technology... :P

Mag follower springs not stiff enough maybe?

Champfer stuff
 

In my WE, the machine work on the brass cylinder piece, where the mag fits in, and the funnelling shapes were the bb's go, were very sharp-edged.

Champfer, smoothen, and polish any bad spots, that may be chooping BB's.

Somenone try the new BBBMAX? They say on their website: no more chopping! And they seem harder and more "maléable"

Yeah, no more chopping because they're so hard...they'll break parts of your gun instead of them breaking.

If the BBs are chopping than that means something is striking them or they are striking something on inside and breaking before coming down the barrel. Would using a sturdier supposedly chop proof BB not cause damage to your internals instead of the BB just breaking? That is how I view it at least.
