I am thinking of getting one of their 1.6mm, Type 2, 7.62x39 receivers with a custom serial number. (My local FFL will transfer it to me for free.) I have E-mailed them twice, asking how long it would take them to ship it out. I have NOT received an answer. Do they read any of their E-mails? I used the one they give in Shotgun News. I don't want to order one, then have to wait several months for it to arrive. How long do they usually take to ship one out?
