Couple of questions about my mp5

First off, I own a echo 1 mp5 full stock version.

I'm embarrassed to say that I've lost the bolt that attaches the stock to the rest of the gun so my first question is where is someplace I can purchase a replacement bolt.

My second question is about a silencer. I don't really know which ones will fit and what not. I mean will something like this work on my gun, or should I look for some specific kind. Thanks for your responses in advance.

maybe something in there?

Any CCW 14mm "silencer" will work. Just so you know, "silencers" for airsoft don't really do anything for decreasing sound. (might make the tone slightly deeper so it's harder to hear) If you are going to put a longer barrel inside the silencer, make sure you change your cylinder as well.

Yeah yeah i know i just like the looks of it haha, so i just want a cheepo one.

Oh got ya ha ha.

Yeah, it should be fine.

If you really feel like saving money, make one out of PVC or something. If you stuff it/vent it correctly, it does suppress the sound to a certain degree. But as stealthmasterairsoft14 said, it mostly just makes the shot sound deeper, which is still an advantage, for high pitched sounds are easier to locate.
