    Incredible Quality

    I got this slide without a barrel to run on my "Fuse for Comp" R11 frame with a ramjet. It performs FLAWLESSLY and is very comfortable to use. The serrations are not very deep but they are very usable. The windows on the slide make the bronze ramjet look beautiful and the DLC finish on here gives it just enough shine to look like a work of art. This slide is also only 1 of 2 aftermarket slides that can accept the sig loc compact, the other being no where near this quality. 10/10 quality

    Green Ano Gets the R11 Ported Slide

    I opted for the ported version and it's perfect!! I haven't had a chance to shoot it yet as I'm waiting on my Green ODG Ano R11 to arrive in a few days! I have two other ported R11 Slides from ECM and I know it will NOT disappoint! Much flatter than my Radian set ups for sure! This will be my 10th ECM R11 build. You get yours yet? Come join the ECM R11 Revolution!
