In over 2 dozen builds in the last 3 years I have found that only a few responded enough to a Adj. V-block to make enough difference to make them shoot-able. Depending on the fit of your barrel to Rec. you may have little or no where for the union to move..in other words the Adj. V-block may do absolutely nothing. I have had some with a fairly loose fit and they of course did respond well...then there are the very tight ones that won't. And the ones that are loose and you crank that adjuster screw tight you may and probably will create a un-true fit of the chamber face to the bolt...;)

When I want to use Dednutz mounts on a build I set it up first with a factory or a PC base and a set of basic rings and check for droop...if I have it I first try the Adj. V-block and see if it responds..if it doesn't I know I cannot use the Dednutz..end of story for that build.. I know I must use some other form of correction..which is either Burris Sig Zee rings with offset inserts or the TacSol 15 MOA base.

My bet is on you needing a TacSol 15 MOA rail and any set of rings or the Burris Sig Zee rings on a PC or factory base, your choice...I will watch this ;)

i appreciate all the help guys. im going to take it apart tonight and look for any humps in the top of the receiver. im also going to loosen the v block screws as im pretty sure they are way to tight. IM an over tightener. also im going to readjust my mount screw and loosen it up a bit im guessing it's also to tight. hopefully this will make a difference.
James...it's not like you will be able to see a hump...they all look the same and yes there is a hump and no there is nothing within reason you can do about the situation but fix it with one of the above fixes....it's not a zit that you can see then pop and it will heal. :D

well i can't really use a canted rail because a dednutz is a mount and rail all in one. How would i go about shimming the rear to adjust for this. I have also heard that you can file down that hump. How do i know where to file in order to make it right?
That is 2 real drastic NO NO's...oh go ahead and take some jokers suggestions and screw it all up...man that is a ugly way to fix..very ugly..Best answer Buddy is sell that Dednutz and do one of the above fixes...really. Go back and re-read post #8. Post that mount in RFC classifieds and it will sell.

As stated the height is not your problem...
The factory base will work fine with the Burris Sig Zee's if its the TO9 and can be used with either the Dovetails or the Weaver style rings...use the lower...the newer guns come with this rail...the older ones came with the junk 3/8" rail. You will need to buy the .020 off set inserts...separate purchase from the rings. They come with inserts but they are not offsets (.00)... Depending on what scope you have the ring height is of course a issue...up to 40 obj. and the factory rail the Med. height is fine..anything over 40 obj. you will need Highs with the factory rail...all depending on the stock and the barrel size...lot's of variables...if ya need help PM me with all the info and I can help.

Clickie and watch the video....

you htink i need the .020 shim you don't think just using the .010 front and back that it comes with will be good.
Do the math....010's will get you 10" at 100..5" at 50.
So if ya have time I would get your scope back to mechanical zero...click it all the way one direction till it gets snug andor stops but DO NOT force it..then count back the other direction till stops and then back half that amount...then go shoot it at 50 on a BIG BOX and see where you are..that way you can get the correct offsets and still keep your internal adjustments near center...the best of all worlds. With all the adjusting you did your first time out you are just guessing at this point...and so am I.

Edit...I just re-read...you are almost out of adjust. at 25:eek:
Get the .020's :bthumb:

that might center the scope but how does it adjust for poi with the rifle?
It doesn't...it simply gets the optics back where it started and where it is at optimal performance...watch the Burris video..it explains how important it is to keep near the center of your adjusters and not get out to the ends...:bthumb:

And when snugging up those screws/bolts use the T2 method...Thumb & 2 fingers on the wrench till tite...if you let the feel get ya there with this method you should be around 20-25 inch pounds
