Help Identifying modified Unertl scope mount maker (Read 1418 times)

	I purchased a Unertl scope with mounts a few years back which said the mounts were "de-horned". (really just the rear mount). It interested me. Looking at the mount the hexagon screw caps are LH threads and lock adjustments in place. When loose the adjustment are made with the knurled wheel as seen in the photo. A tag with the scope said the adjustments were 1/8 MOA but I have not checked that yet. So, to make a long story longer, the workmanship is exceptional, so I wonder if anyone knows if someone (or some company) was making these specific alterations to Unertl mounts?

	They are factory Unertl mounts designed more for hunting than target shooting.

	Although not near as common as the Unertl mounts with tall adjustable turrets, Unertl also made de-horned mounts. Yours were made by Unertl. Wayne

	That didn't take long, thanks guys. Just goes to show I should have checked the old catalogs first. Much appreciated.

	Of course I have a funny de-horned Unertl mount story. I was watching one mount on eBay on my phone and had made a fairly low bid and with a couple of hours left was the high bidder. The phone was in my pocket when I received a notice on my computer that I was the high bidder after getting out bid a bit earlier. I thought to myself "WTF?" and saw that my high bid was $666. I had butt bid that amount. The bid was at about $134 as I frantically called eBay on the phone. The eBay employee agreed that my $666 bid was probably unintentional, but since the auction was closing in less than an hour the bid could not be retracted. They did however say that I did not have to complete the transaction and that they would notify the seller and if for some reason I got negative feedback they would remove it. In the end my $134 bid was the highest and I decided to pay for it and eventually sold it here and made a few dollars on the deal. Jack

	My Unertl 6 power ( 13.5 inches long ) , has this exact same rear mount. Searched long and wide for info and found nothing, until now. Always figured a hunting application. Thank you for this, gents. From Rabb.

	as far as the 1/8 min. that is dependant on the spacing of the mounts. 7 1/4" is the normal spacing which in regular mounts translates to approx 1/4 min clicks. Longer spacing makes the adjustments get smaller.

Longer spacing makes the adjustments get smaller. In a practical sense, yes (IE most target scopes are 1/4 MOA at 7.2 inch spacing) but you can design mounts for any MOA adjustment at 7.2 spacing (within reason) you want depending on the rotation between "clicks" IE TPI of the adjustment screw.

You could design anything, but none I've ever seen did so. And reworking turrets for smaller increments wouldn't make sense when all you really need is to extend spacing about 3" to get smaller changes.

And reworking turrets for smaller increments wouldn't make sense when all you really need is to extend spacing about 3" to get smaller changes. I'm not an engineer but I would think doubling the TPI of the drive screw (not a technical term) would result in one half the advancement of the aperture. Redfield International rear sights and International Mark 8 sights, I believe, are the same with the obvious exception that the Mark 8 is 1/8 vs 1/4 MOA. I would guess the difference is thread TPI is twice that of regular International....but again, I'm not an engineer and getting off topic, I guess. Regards

	Many people confuse MOA with 1". 1 MOA @ 100 yds is 1.047 (and some change). The base spacing for MOA is 6.877. If you change your base spacing to 10.8, that will give you .166" per click, instead of .25".

	Andover, yes your right you could but we are just talking about factory mounts by Unert (mounts in question), Lyman, Fecker. I dont know that they varied there mounts.

Yea, the 1/8 MOA came up when I started the post because there was a tag on the scope/mounts that said 1/8 MOA and the discussion kind of drifted from there. I guess I'll get it on a rifle and shoot it since we are finally getting some decent weather here in MN and let everyone know the results. Thanks for the input. Chris
