30MM lapping bar(04.04.2010)
I used this 30 MM lapping bar for the rings on a new NF 8X32. It worked great. at start I had .020 gap on both sides of the rings with hard points on rear of both sets. After lapping, I had over 80% contact with tube and just onder .010 gap at ring split lines. I now have a 1" lapping bar to go with this one.
Everyone should have one of these!(30.12.2011)
I don't think you can get any better quality in a lapping tool. This thing is solid steel and very heavy duty. The multiple handle attachment points are very nice as well. This item comes with the 800 grit lapping compound which worked very well but took awhile to get full 80% contact on the rings. I would recommend purchasing the 600 grit compound separately to speed the process up a little bit or buy an extra six pack of beer. Overall I am very satisfied with my purchase and will be purchasing a 1" model to go with this one.... and some extra 600 grit compound.
disappointed...(24.03.2015)
it's just a piece of 1 3/16 raw cold rolled bar. The lapping surface is not machined. Mine spec'd out at 30.06>30.12 I didnt even bother to check the run out. I measured all my 30mm scopes and they were all 29.95 and mounted in Mark4 steel rings that this bar will never touch
A better product than cheaper versions(24.11.2010)
Unlike cheaper versions from other suppliers, this lap has grooves for carrying lapping compound. It also has multiple handle attachment points, which is important when working rings that are very close together (or very far apart), or when the structure of the firearm only allows access from certain positions.
A few quick passes will let you know whether you're close ... and to keep going ... or you're not, in which case you may need a reamer (such as the one from Clymer) or perhaps a new set of rings.
