scope could also jump up and give you a black eye if on a high power rifle
Scope eye trademark of many an inexperienced shooter. Lol.
Looks like a good little tool and a bit easier than the plumb-line process I use...May have to see if I can get one. Also, I've never used Loctite on my rings...You use it on the screws or where the rings meet together?
On the screws. Just use the right type that is designed to be removed. This keeps them from working loose even if not tightened extra hard. Doesn't take much, just a drop. Great for any screws that may vibrate loose over time. The kit is still like only $20 U.S. at Brownells and other. Not sure what shipping like over there but well worth the time savings.
$20 is $28 here, postage is likely to be at least the same so under $60. Seems reasonable.
I use Loctite on other stuff, never felt I needed it on the guns, but it makes sense...As long one uses the right colour.
