I’ll add in my experience with this cover. I have one of these for my US/UM OG and OG 6.5.
Pros:
- Fits tight and does not move once it is on.
- Provides mirage protection for approximately 20 shots before the rifle needs to cool (approximately 2-3 rpm of .270 or .25-06)
Cons:
- On a rainy day, immediately turns into a heavy and wet sponge.
On the whole, I like it better than the Cole-Tac covers I have on my AB Raptors and Scythe Ti suppressors.
