Got the barrel fast and the day I got it I fired 200 rounds and it was spot on. Only problem is the picture shows it black with either dlc or melonite but the barrels is stainless. Should have read the description better that’s my fault. I bought the barrel for use with a t-comp but the barrel is a little long so it looks funny with the comp not sitting completely flush with the face of my Glock. Other than that great purchase for the money.
