I have an FN BCG and Milspec charging handle for sale. Both were taken from an FN 20" Upper Receiver. The BCG was manufactured by Aero Precision for FN. The BCG is manganese phosphate, and the Bolt is HPT/MPI tested.
Asking $155 cash for both the BCG and charging handle. I'm by the Friendswood area, but if you're no more than 30 mins from my house, I don't have a problem meeting halfway or whatever works best for you. Thanks for reading my post, have a good one.
