Came with MX2000 I just bought and will not use. True 34" with 5 notch adjustable rib front and back. Wilkinson has worked his magic on the barrel along with creating his famous flush thinwall chokes for the barrel. The 5 shown are included with the barrel: 0.035, 0.030, 0.025, 0.020, and 0.015. Barrel is stamped 1.66kg but weights 1.62kg with a choke installed on my kitchen scale (or my gun scale that the wife lets me keep in the kitchen, haha). Barrel is stamped BM indicating 1999 build date. Also have rib adjustment tool that I'll make sure comes with the barrel. $2900
Honestly don't know since this is my first P gun. The unsingle sn isn't matched to the receiver (the o/u barrels sn that came with it are) so I don't know. Is there an easy way to tell?
Being that the rib height matches close to the 2000/8 o/u, I would say it's a standard MX2000. The RS would be too tall for the MX8 ramp rib style.
MX 15 barrel serial number range and rib ????????????????? Can you show Wilkersons name on the barrel should be by the side of the barrel near the mono block?
Serial number and wilkinson stamp are both on the bottom of the block in my picture above...but there's some glare on the wilkinson stamp so here's another picture with different lighting.
Confirmed that its not an MX15 barrel and is indeed an MX2000 unsingle barrel and will match rib heights on the MX8 or MX2000 just fine. Also has the type 4 lug if that wasn't already clear.
