Missing buffer tube and castle nut - Sylvan Arms Gen2 CZ Folding Stock Adapter

I bought thinking i was going to get the buffer tube and castle nut and i did not?? The folding adaptor would not lock into place whrn you closed it to extend the stock out i have to grind the inside of it to allow the lock to click into place . Was not that big of a deal since i had a dremel but for someone who doesnt have one i would not recommend it. I called optics planet and they were going to contact sylivian arms to try and get me a buffer tube according to there website the buffer tube is supposed to be included ? I dont think i will ever get it so i gave up and went another direction. If you are going to order this just know it doesnt have buffer tube and castle nut and it might not lock into place when extended out...
