Scope blocks are available in many configurations and heights.  The list below shows the more common, in-stock items.

Blocks are unhardened, black-oxide finished, and for both round and octagonal barrels, unless otherwise specified. 

Hole spacing is .560" front and .860" rear, unless noted.

Prices are for individual blocks, except for Springfield blocks which are priced as a set.

Screws are an additional $1.50 each, and shipping is $4.50 for the first set, $1.00 more for each additional set.



Please note that this product line is all directed towards the 60 dovetail, external-adjustment type of scopes.

I do not carry any products for the "modern" Weaver or Picatinny sort of mounts.






Standard blocks are available in heights of 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 5/8", 3/4", and 1".  The base has a slight concavity which allows them to mount on either a round or an octagonal barrel.  Heights are measured from a flat surface.  They will sit .005" to .02" lower on a round barrel.  They have the Lyman/Unertl crescent on one side and the Winchester dimple on the other. 


Price: $12.00 each; 5/8" and taller $15.00 each



Flat-bottom blocks are specifically for mounting on an octagonal barrel.  They may "rock" on old draw-filed barrels; in that case, use the standard blocks (above).  Heights available are: 3/16", 1/4", 5/16", and 3/8". 


Price: $12.00 each



Posa blocks are for use with Unertl Posa-mount rings.  They are available either Posa/Lyman combination or Posa only. They can also be used with the Redfield 3200 scopes.  Heights available are: 3/16", 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4".  Available color-cased also.


Price: $12.00 each black, $16.00 each color-cased.

5/8" and 3/4" high are $15.00 each - black only.




Color-cased blocks are available in several configurations, including standard, Posa/Lyman and flat-bottom.  Heights available are: 3/16", 1/4", 5/16", and 3/8".  Flat-bottom are 3/16" height only.


Price: $16.00 each


Stainless Steel


Stainless steel blocks are available either in standard or Posa/Lyman configurations.  Heights available are: 3/16", 1/4", and 5/16". 


Price: $20.00 each; stainless screws are $2.00 each



Blocks for Fecker mounts are slightly narrower than standard.  (Lyman and Unertl scopes will fit Fecker blocks, but Fecker scopes may not fit standard blocks).  Heights available are: 3/16", 1/4", and 5/16". 


Price: $12.00 each 

1903 Springfield


These blocks duplicate the blocks provided on 1903 Springfield rifles.  Also available in Posa configuration.  Either color-cased or black finish. 


NEW for 2013 - heights that are .100 or .200 taller than the standard.  This allows for low-height scopes such as the Lyman to clear the bolt handle.


Note - a lot of questions have arisen about using "Springfield" blocks or Unertl O & E blocks.  Functionally they are identical.  My understanding (and I am not an '03 expert) is that the "Springfield" blocks are the style that would have been provided by the armory, and that the O & E is what Unertl would have provided with their scopes if intended for an '03 rifle.  The Springfield-style blocks with the slightly rounded ends take more time to produce, and that accounts for the price difference.


Price: $36.00 per set

Unertl O & E


NOTE - approx. June 2104 - this product is going to be discontinued.  These blocks are basically the "not pretty" version of the '03 blocks above.  Most people have been buying the specific '03 blocks rather than the O & E, thus the decision to not continue making these, since they have not been a popular item.  Sales will be limited to stock on hand.


These blocks duplicate the Unertl O (rear, .230" high) and E (front, .470" high) blocks.  Available either black or color-cased. 


Price, black: $12.00 each; color-cased: $16.00 each



These blocks are specifically for Stevens scopes.  They have the original-style V-shaped locking groove, and are available with either Stevens holes (for 5-40 screws, .700" and .825" spacing) or with standard holes.   They are also available flat-bottomed.  Heights are 3/16" and 1/4".


Price: $12.00 each 

-70 series


These are the front blocks used on the Winchester Model 70 target rifles, with the 1.750" hole spacing.  Heights are as follows... A-70 - .170";  B-70 - .230";  C-70 - .315";  LC-70 - .370".

Also available in Posa configuration.


Price: $16.00 each

Mann-Neidner blocks


These are the tapered blocks for Mann-Neidner mounts, intended to tighten on recoil.  They are specifically for use on '03 Springfield rifles.  The bottom of the front block is cut to the barrel taper, so that the block sits level. 


Price: $50.00 per set

Cross-dovetail blocks


Meant to go into a standard 3/8" x 60 barrel dovetail.  The lower ones are usually used for front sights, and the taller ones for a front scope mount, when it mounts into a rear sight cut in the barrel.  The lower ones are either 3/16" or 1/4" high.  The higher ones are duplicates of the Unertl BK, K and KK blocks.  Any of them can be provided with the brass set screw.  I have some that are intentionally .005" larger, to be filed to fit.


Price: $24.00 each

Vaver blocks etc.


These blocks are for Vaver front sights.  They are available either for the sights with the little pointy clamp screw, or for the ones that use the side clamp ring.  Heights are .100" or 3/16".  The .100" high blocks require special low-head screws.  The clamp rings are also available.


Blocks - $12.00 each

Screws - $1.50 each

Clamp ring - $5.00



We have many blank, undrilled blocks on hand, already black finished.  Drill them yourself, or let us know what hole spacing you need and we will do it for you.  Heights available are 3/16", 1/4", 5/16", and 3/8".


Price: $12.00 each



Screws are available for all block heights.  Standard thread is 6-48.  Stevens screws are 5-40.  But don't worry if your rifle has yet different tapped holes - I currently have screws in sizes of 6-32, 6-40, 6-44, 8-36, 8-40, 10-32 and 10-36.  We should be able to find it there!


Price: $1.50 each; Stainless $2.00 each

6-48 Taps


New for 2014 - set of taps (plug and bottoming) for standard 6-48 scope block mount holes.  These taps are 4-flute HSS, made in USA specifically for Steve Earle Products.  Sold as the set of 2 only.


Price: $40.00 per set
