Easy to install, definitely has a "wow" effect on those who see it. Adds to the mil sim appearance of your marker if thats what you're going for. If you have a spec ops mil-sim grip you have to do some trimming to make it fit. My only gripe was they didnt include an allen wrench that fit the tiny screws that are in the adapter for it. I had to hunt through all my tools to find one. It also will add to the number of steps needed for you to remove your barrel in case you pop a ball.
Lapco makes really nice stuff and thus far I have been very impressed with everything I have purchased from them. Even though the suppressor doesnt officially work, I still would recommend it as something cheap and fun to do if you already have the Lapco 8'' bigshot barrell.
