6" Glock Barrell with compensator in .45 ACP

For sale is a used glock barrel with compensator and required hardware. Barrel is used, unsure of how many rounds shot, bought it many years back hoping to aquire a 21 but that plan is gone now obviously. Still in good shape. Must have valid PAL. Ill add more pictures by end of day. 

Length is 6" OAL including compensator, anyone looking for increase to accuracy and decrease on recoil definitely check this thing out. Fits gen 1-4
