suppressors are nice but expensive. You will have to first pay a one time $200 dollar tax, then go through some minor paperwork, bring to local police station for fingerprinting and a few signatures. After a few months for the ATF to check your backround, you can then purchase the suppressor. The only thing is that you have to get it at a class 3 dealer. There are very few around in each state (they are not your local classic gun shop). suppressors are exactly what you pay for. If you are going to buy one, go expensive. AAC, gemtech, surfire are a few quality companies. a cheaper one is around $500 and an expensive is around $800. not much of a difference in price but quality for sure. There are many diff. sizes as well with suppressors. Bigger the more quite, but less accurate. who is going to shoot distance anyways with a suppressor right? I forgot to mention earlier, you may need to get a aftermarket barrel for you gun simply because it must be threaded. A company named Jarvis makes them for some guns. I own a AAC evo and it is absolutely perfect. Good luck!
