Stripped buffer tube
 

So I recently bought the Ares M4A1 and found out the buffer tube wobbled a lot, so i removed it and found out that the tube was stripped, is there a way to fix this, or do I have to buy a new buffer tube.

The buffer tube is stripped? There isn't a bolt holding it on? If it is a bolt just replace it..I am pretty sure the bolt screws into the Spring guide through the gear box.. I may be wrong in your case. If anything you might have to replace it or maybe use a die and re thread it..

The new ARES M4A1 take real receiver extensions. Buy a real one and screw it in.
