They improved the seals and made a few minor improvements to make them more durable in the field. The range markings extended out to yards for the 50 BMG, instead of yds on the original scope for the M40A1. These seem to have serial number range of "5XXX" - but I have not studied this in depth. I told myself if I can find one of those three parts, I will undertake such a project.Īs far as I can tell, there are about 6 U.

Avoid using the word "mount" when talking about scopes! That can be either the base or the scope ring, and this causes confusion.Ī sight "mount" is correct terminology, but note that it is not a scope mount.

These may need mounts which constitute "specials", which we cannot take on at this time We have many old Unertl and Lyman mount charts for reference - including info that is confusing, contradictory, out-of-date, or just plain wrong!Īdditional technical scope block information We certainly do not claim to know everything in this field, but with experience, many trends have become visible. If we don't know, we'll just say so! There are a lot of shooters and shooting forums where the information you are seeking may or may not! Many less-common scopes, sights, and rifles are out there. When we have information that we believe is correct, we're glad to pass it along. We are not familiar with every possible combination of obscure rifles and sights or scopes being mounted on them. We do not carry any products for the "modern" Weaver or Picatinny sort of mounts. On-line ordering of scope blocks could be problematic due to the vast range available. Prices are for individual blocks, except for Springfield and Mann-Neidner blocks which are priced as a set. Blocks are unhardened, black-oxide finished, and usable interchangeably for either round or octagonal barrels, unless otherwise specified. The list below shows the more common, in-stock items. Scope blocks are available in many configurations and heights.
