The butt area moves making it unpredictable in terms of bringing it to the shoulder effectively over time.
I have been a sucker for underfolders for ever since I remember and
this is the first time when I hear that it moves. Do you mean that it is lose?
The AK underfolder (any make) is perhaps the stiffest underfolder out there,
even the ones that have seen a huge amount of service,
when I compared it to any other gun with underfolder (non AK) that I have put my hands on.
Usually, if nobody fukc'd with it, like taking it apart, bubba'd it or whatever,
the underfolder will keep its joints stiff for a very long time.
That, in short, is because it was designed right.
People were complaining that it was too stiff, not too lose.
i bought it several years ago when people was pooh poohing the underfold , it seems nobody wanted them , as you can see some people still dont like them .
i like them so much that i gave them a good home .
Yes, I know. I remember that. There were quite a few people complaining about it.
I remember in my very early days on CGN,
when I was so happy because I convinced Dlask to make that short run of them.
I had that in mind since very long before that.
On CGN, member Powerwagon, and maybe others as well, mentioned the idea of
putting that underfolder on VZ (long before I joined the modern CGN),
and now was the first time it took flight.
But as soon as I posted about it, with pictures and everything,
the complaints started almost instantly, by who else than Deckard (of course).
Whaaa, whaaa, it's too high, nyah, nyah, it doesn't clear the magazine,
b!tching and whining and sniveling. That guy always hated me.
There is a reason it was dropped by modern armies.
And the reason is?
No matter what the modern armies do,
that underfolder, on the AK, is a nostalgic thing to lots of people.
Yes, it has a poor cheek weld (as said in another post, paracord might help).
Yes, it is slow in deployment.
On the other hand, it is very solid/stiff,
and together with few other underfolders/over-the-top-folders,
the absolutely most compact folder ever (in the folded position),
if used on the guns it was designed for.
Dlask made only few of those adaptors, 40-45 pcs, or something like that.
It was only meant like a toy, as I said, more like a nostalgia thing.
There are a ton of folder designs out there,
so people who don't like the underfolder have where to choose from.
