Agree, I think I misunderstood your point.
Let me clarify on the receiver I broke. The rifle belonged to a friend and at that time DCM would exchange any low number '03 receiver, regardless of condition, for a DHT or NS receiver. We had been firing the rifle the previous day, maybe 200 rounds of M2 ball with no problems at all. Then we stripped the receiver and were ready to pack it up when I decided to see if they were really brittle. When the pieces hit the floor, I think I turned a bit green, thinking of all that firing the day before. Unfortunately, I did not record the serial number. We finished packing up the pieces and shipped them off; the replacement receiver, a DHT that looked new, arrived a month or so later. There was no mention of the condition of the one we sent them.
