That thing is long! Sort of reminded me of a punt gun. Congrats on the new beast, enjoy it!
Well, I hit a snag with the 725VTR. I can't get the cocking lever to breech block pin out with hammer and punch. Asked around a bit and wound up ordering this heavy duty chain breaker to press that overly-tight pin out.The cocking lever pin is actually a rivet. The hole is countersunk and the rivet pressed in with a hydraulic press. I replaced a barrel on a Benjamin Titan and I had to carefully grind off the flare around the rivet in the countersink. I didn't reuse the rivet. I replaced it with a metric spring pin. It actually works better with the spring pin. The original rivet was soft and had shown signs of wear. The spring pin is tempered steel and has held up well with thousands of shots. I hope this helps.
