Used this with a VLTOR A5 Buffer and a Sprinco 308 orange spring on a CMMG 45 acp upper. Setup worked with no problems and brought my ejection pattern to the 3:00 spot. Buffer tube is spotless but smells a bit like oil since I lubed the bolt carrier group a lot. Threads are fine and comes complete with end plate and castle nut. PayPal and zelle accepted. Ships by USPS with tracking number included.
