MDT folding stock adapter - carbine-to-carbine - one-way locking - BLK

I am selling a used MDT folding stock adapter - Carbine-to-Carbine with one-way locking in black. The adapter has some glue residue and a safety hole but is fully functional.

I think I only folded the weapon three times in the last two years, so it can go.

The adapter costs €219 at Brownells with a long delivery time (ArtNr. EU2004266).

Regarding the photo in the installed condition: WITHOUT weapon, without scope, and without stock, just the folding adapter!
