Great purpose-build rail for your owl! - Cloud Defensive Cloud Optimized Rail V1

I found that when running my OWL with a Elcan 1-4x, my fat thumb was often in the lower 1/3 of the sight picture if I was holding in a c-clamp. This drops the OWL pressure pad enough to where it is no longer an issue.

Pros:
1. Perfect fit for the OWL from Cloud Defensive.
2. Uses BCM hardware for mounting (mine actually has the BCM patent number on it, along with the MI markings). Easy to install.
3. Lightweight.
4. Great for 10.3 to 11.5 in builds.

Cons:
1. Gas block is a very tight fit; if it's not low profile it isn't going to fit.
2. No room to mount a front sight - make sure your optic has irons!
3. Check your muzzle device; some are a little wide at the base (YHM), where a 10.3 barrel would be pushing it to correctly mount the device.
