Stay away from Cobray.com!!
Just an FYI, I wouldn't shop at Cobray's online store again if I had a choice.
I was waiting for my first class 3 gun (a NIB Cobray m11/9) and figured I would pick up a few essentials before my Form 4 came back. I got on Cobray.com and placed an order for a new buffer, a front strap, and the original M11/9 SubMachine Gun manual. I had my order within a week (even though the site claims it could take up to 6 weeks). When I opened the padded envelope, everything was there, but it smelled like an ashtray. The contents of the envelope were so saturated with smoke that it made me sick to handle them. Everything I touched (as well as anything that any of the items came in contact with) reeked like cigarettes. I was able to clean the buffer and strap (with several treatments of febreze), but I couldn't do anything with the manual. After several failed phone attempts, I was finally able to reach somebody at Cobray. They said that they had had problems in the past with smoke damage (apparently their stock of padded shipping envelopes were in a warehouse fire), and that I could return it for an exchange. I asked him how someone could overlook this, and still ship out the order with the envelope in this state (to which he had no idea). I shipped the manual back at my expense, and waited several weeks with no replacement. After about 3 weeks, I began calling several times a day. I left several messages on both their customer service, and order placement phone lines, and still received no response. I finally sent out emails to every address I could find on their site (3 or 4 total). A few days later someone emailed me back stating that my replacement would ship the following Monday. Another week and a half went by with nothing, so I started calling again. I was shocked when someone actually answered the phone. He said the manual would ship out next week. When I finally got the replacement manual 10 days later, it was in another of the smoke filled envelopes, and reeked worse than the original (even though I included a note with my return asking for them to check that they used a "smoke free" envelope). I had no choice but throw the whole mess away.
To top it all off, when I finally got my gun, and went to install the new (factory) buffer, it wouldn't even fit!:wtf The replacement buffer I had bought directly from Cobray, had the guide rod hole located to far from the spring pin hole (so that the buffer was rotated about 30* when both rods were in their holes, and wouldn't even fit back into the back of the upper receiver). I actually had to take the buffer to the drill press and drill a new (correct) hole.
I will never buy from cobray again. Their customer service is terrible, and their products inferior!
