Is the back blast/recoil on a 57mm/106mm RCL Rifle(s) set at "The Factory" or can it be adjusted by plates and screws at the Venturie (sp?) Port at the breach block?
Any considerations that need to be taken into acount when bore sighting the 57mm RCL vs the sight picture on the scope when "Bore Sighting".
Hey, I'm just a dumb 12B at heart. The finer points of the weapons MOS are lost on me. I do have a funny story about a 57mm RCL Rilfe I'll tell some day.

I lied, I don't have "Change 1".

But the back blast on the 106 is fixed. "Triangular in shape with the apex at the breech. It extends 39 meters to the rear and has a 46 meter base." It is divided into two zones, a danger zone and a caution zone."

ROFLMAO... that isn't the first time I've heard that.

I participated in a live fire with the Philippine Marines where they were firing one of those. They seemed to skip the item on the gunners checklist to check backblast area quite a bit. Then again, they also seemed to skip the whole "Aim the gun" item too

(and clean the gun, check the barrel for obstuctions, inspect ammo etc...)
