Just to pass some info on. I purchased and was billed for a muzzle brake on June 16th from SKSMAN. On July 2nd I received a copy of my credit card receipt and their business card in the mail....nothing else. Since that day I have sent emails with no response. Additionally their phone is apparently off the hook as it constantly rings busy, regardless of the time day or night. As a result 30 days after the original transaction I filed a mail fraud complaint with the US Postal Inspectors and also started a credit card reversal. This guy certainly has no trouble in using his computer for orders but apparently has a problem with shipping and complaints. Be Aware when dealing with this guy. Another site shows other people having problems also.
