I haven't noticed it, but it's possible. People originally thought they were great budget pistols as they were only £90 or so, but then people realised that they need a load of fairly pricey upgrades because they eventually explode, making them more expensive than just buying a TM and being done with it. Also, full-auto gas guns can be temperamental in our lovely climate, so using the fun-switch isn't always possible. Maybe people are realising this now?
I find it amusing because I'm actually looking at completing my AAP build and potentially getting the folding stock and a vertical grip/flashlight combo and maybe some extended mags and having it be like a small SMG for a sniper sidearm
They're relatively cheap pistols. They will always be available and as time goes on more and more will enter the market.
On some sales groups they're as cheap as £65 brand new.
@ak2m4AAP uses standard GBB cut and the stock is 129mm long with a o-ring channeled in about 5mm from the end.
The only aftermarket brand who have copied this design I've seen so far is PDI
