well after installing and using the surefire branded quick disconnect silencer today on my m4 I must say it was an excellent add. Granted all it really does for you is add looks but if you don't want a silencer on when you move to a tighter quarters you can simply unlock and pull off and throw it in a dump pouch or pocket and BAM!! you have a regular black flashhider/compensator on your gun. I would definately recommend it for people looking to add looks to their gun but I would watch the price as they are 85bucks luckily I got mine in a mystery box so it pretty much cost me nothing. I'll have to see if I can't get some pictures up and post them along with the review on it but if anyone is going to be at grab and go and wants to take a look let me know I'll be more than happy to let you mess around with it.
