Last year I ordered a 45 cal ML barrel for my Contender. I am very happy with it, the quality is there. Last week I ordered a 223 carbine barrel, and David stated it would take about 3 1/2 weeks. I am not a gunsmith, but even when I compare David's weld to attach the lug with others, it is top notch. I also have Bullberry, and Russ Carpenter barrels, and David's barrels are definitely on a par. If you have questions, you can email me at luredaddy@aol.com
