OK, here's the situation. On my last M4 rifle I had my Aimpoint ML2 mounted in a railgrabber with spacer. Now I am in the process of putting together an upper package for an incoming rifle. I bought a new Colt LE6921 M4 flattop upper and want to use my existing ARMS#40 BUIS and Aimpoint ML2 on it. I want to co-witness my irons as well. I am wanting to step up to the ARMS #22M68. One of these days I may get an ARMS #45 SIR as well. In the meantime, I'd like to use the ARMS #22M68 that extends out over the delta ring to get me as far forward as possible on my standard flattop. Is this extension part of the mount, or is it a spacer? Does it have a name/number? What spacers will I need (if any) if/when I go to the ARMS #45 SIR? Thanks. |

The #22M68 is the ring and base, with no spacer. You need to additionally order the [b]#22M68EXT[/b], which is the full-height cantilever spacer. ARMS also makes a full-height and half-height straight spacer, but you won't need them for either of your applications. When you eventually get a SIR, you'll simply remove the cantilever spacer and use the #22M68 without it. This modularity is a HUGE plus for the #22M68 over other mounts. -Troy |
