Great product, and I would absolutely purchase again. However, there are a few things that the manufacturer should consider doing.
1. Make a separate line designed specifically for rifles with a large suppressor.
2. Add an additional product that could be purchased as an addition that would help seal, or "close up" the cover when walking. This could be a bungee of some sort, a rubber strap type of product. Something silent to take off (not velcro).
I am totally happy with this product for its current application. If you're not running a suppressor, this thing is perfect! Im sure it will fit smaller suppressors just fine, but I have serious doubts that a larger can like a TBAC Magnus with a cover on it will fit. It's already fairly snug around my bare brake. Anyways, thats just my two cents.
