Why your KA M4 doesn't assemble properly.

[m102404]

I haven't found a great way to get these annoying "working bolts" to stop jumping out of place when reassembling. Or worse, they get a bit bent out of shape and then they rub or don't move freely.

Shame that so many companies do it now...one of the worse "innovations" ever adopted.

It's like getting the trigger assembly back into a V3 or solving a rubiks cube...just sort of happens sometimes.

I've only ever ran into this issue with KA guns. I find that everything that KA makes is ever so slightly smaller than standard.

I actually have no issues with the fake bolt and bolt catch...
