I bought this to ultimately use with a Griffin Optimus on an AR build. The machining feels fantastic and the mount feels extremely solid. It mates cleanly with the Griffin taper mount flash comp and seats tightly. I haven't had a chance to take it out yet, so I can't comment on any performance characteristics.

There are some things that aren't obvious, however, that Griffin could improve on. First, it would be nice to have a compatibility matrix with different mil-spec firearms, suppressors, and the various mounting options Griffin offers. Griffin has changed their supported configurations but haven't always updated the manuals or documentation to reflect that.

After attempting to piece together which adapters work together I decided on the GA full sized flash comp, the Optimus, and this blast shield for primarily shooting .223, 5.56, and 22LR with plans to use the Optimus later with .300 blackout in the future. Through various comments and discussion this configuration seemed appropriate for a mil spec AR but when I received the blast shield a sticker on the box indicates that it only supports minimalist taper mounts for the Optimus. I'm hoping this means only in the cases where the additional rifle baffle is added, but the docs are unclear. This is hardly an exotic configuration (pretty mundane, really). It would really be nice to have some kind of tool to select a supported firearm and suppressor and get any supported mounting options and suppressor configuration. If not

Other reviews were upset that the current version of this thread protector are made of aluminum but I think it's great. The thread protector is precision machined, mates beautifully with the taper mount flash comp, feels great in the hand, threads on smoothly, and because it is aluminum, is very light. For a sacrificial, protective item I'd much rather have the weight reduction than unnecessary durability.

While I'm waiting for my tax stamp I'm glad to have a nice lightweight way of protecting my muzzle device. The knurling is grippy making it easy to hand tighten and remove without tools. That said, the mating with the taper mount is very tight and I found that it required a bit more force to remove than to mount (bother were done without tools).

The thread protector does add a bit of volume to the muzzle device that I'd prefer not be there for aesthetic reasons but far less than something like the Minimalist blast shield (though it also provides no functional effect, unlike the blast shield).
