I purchased this PFS last August, used it 4 months firing about 1000 rounds, and sold the CG. Although I have not sold any items on TS, read it for years, I do have a long track record on EBay dating back to 1999, 200 plus buys and sales with a 100% positive feedback record. I will be glad to verify that statement. This PFS is the new unit with the bracket that locks the two pistons together. 900 dollars will bring this unit to your door, insured with tracking.
