Yes. On Black Friday, I ordered a completion kit from PSA which was their PTAC package with a .22lr conversion kit. That was about $500 when everything is done. Yesterday I purchased a lower for $50 (blemished). If I sell the .22 conversion kit for, let's say $100, then everything comes out to (approx.) $450. I already have a rear sight carrying handle (2 as a matter of fact). Let the assembly begin!
