Scope base measurement question

[MachV]

Just checkt the NF 20MOA 1 piece base on the SSRem action.Kinda tuff to get an exact measurement with it all mounted up but looks like your good to go.
It apears they are .3 in hieght also and the slots are .4 apart,.2 gap and .2 spacer

Badger bases are 1913 Picatinny spec- NOT Weaver. Farrell's aren't to any spec. Stick with Badger then Nightforce but I would stay away from Farrell.
Just my opinion...

Need a measurment from a BO and a NF 1 piece base (20 MOA) from anyone able. I need to know the hight from the top of the crosslots, the very top the rings set on to the point where the top of the reciever contacts... This measurement must be on the frontend of the base and not the rearend of it.

I've got a set of Ultra High (AR15) MKIV rings and need a base that measures .250" thick or better to get the NF 5.5-22x56 to clear the barrel block on the new 30.

My brothers 2 piece NF base measure .300" tall and just wanted to make sure the 1 piece up front did too, .300" thick would be even better than .250". I know the Ken Farrell base is .400" tall and would work perfect, I just want one with a recoil lug on it and the NF is what I'm looking at for this right now.

Another question...

What's the spacing specs for the cross slots on the Weaver style bases like the BO and NF use vs. the what Ken Farrell uses?

My dads Farrell base has .400" spacing and square cut slots for his 700LA.

Thanks a bunch in advance. [img]images/icons/smile.gif[/img]

Thanks CJ, and Chris. [img]images/icons/smile.gif[/img]

Anyone know exactly what the 1913 Picatinny specs are?

Thanks a bunch. Off hunting this afternoon...

Looks like .394" CTC.

FWIW, the NF 2pc. base was not .394", it was .4" +- .001" "maybe", but definitely not .394".

Anyone have a Badger base to check and see what it's spacing and height in front is?

[J Schulze]

spacing dont really matter as long as the groove is the same dimension to fit the rings properly. INteresting no tolerance givin on the center to center dimension

[Brent]

For me, spacing is most critical, as I want to switch a scope between two rifles and they must fit perfectly on both.
