Recomend a folding stock adapter for an AK

[JustinJ]

I'm looking to install a folding stock adapter with AR gas tube. Which are good and which to avoid? My primary concern is reliablity and durability. I really dig the Make M4AK based on how sturdy and tough it appears but $360 is a bit steep.

Kinda wanted this one myself.

People say the bonesteel one is strong. I personally find it unsightly. I haven't used it so I can't really comment beyond that. Two other options are ACE and stormwerkz. The ACE and stormwerkz ones have a pretty long track record.
