When I started using the Hawkeye® Borescope, I was amazed at
the clarity of the view with this relatively inexpensive and easy-to-use device. The Hawkeye gives you an up-close and magnified
view inside a rifle barrel, so that you know precisely what is there, without guessing. Without a borescope you have no way
to know what is going on inside your rifle's bore because you simply cannot see it. Holding a barrel up to the light and
looking through it from one end is all but worthless, when it comes to judging its condition.
After looking through
scores of barrels, I have gotten an education about all sorts of things and these are just some of them:
|The condition of a new barrel |
What is the surface
condition like? Have the reamer marks been lapped out? Are there major blemishes? Was the chamber throat cut concentric, indicating
a straight barrel in this region, or is it longer on one side? How smooth are the chamber and throat?
Is the cleaner really working? How much
more scrubbing is necessary, and where? Is my cleaning method damaging the bore?
Exactly how worn and rough is my chamber
throat? How far down the bore is heat cracking present?
How fouled is the bore and where does
fouling occur — in the bottom of the groove, on the leading edge of the land, on the top surface of the land —
|The condition of a used barrel |
Are there nicks,
corrosion, fouling, or excessive wear
