Wanted: WTB B&T Telescoping Stock and/or any 3-Lug/Tri-Lug 9mm devices

Looking to buy a GHM9 Telescoping Stock. I currently have the A3 Tactical version but it’s just too high (or too low) on the receiver for me. Can trade if there’s any interest. 
 

also looking for any 9mm 3Lug muzzle devices, specifically the Angstadt Blast Wave.
