Description
Features: CNC Machined from Solid Steel with Black
Oxide finish. Made in USA! 100% Lifetime Warranty. Front Sight Adapter Ring
allows for the use Original Post & Globe front sight (that has been removed
during barrel shortening) of a Mosin Nagant 91/30 without permanent
modification to firearm. It is designed to fit over tapered barrel of the Model
91/30 and be locked in place with two opposing set screws. The Original
dovetailed Post & Globe front sight can then be pressed in to adapter. The
adapter has been design to maintain the original sight line.
Fits:
The M9130 ONLY!
Fitment Instructions
Requirements:You must measure your barrel length correctly
in order to choose the proper model. Barrel length is measured from the end of
the barrel to the closed bolt face. (Always practice proper handling
techniques, safety precautions, and ensure an UNLOADED condition before
attempting to measure barrel length.) Close and lock bolt on UNLOADED chamber.
Insert a ¼” diameter wooden dowel or other appropriate reference device that
will not damage barrel into rifle bore from muzzle end until contact with
closed bolt face. Mark dowel at end of barrel, remove dowel and use tape
measure or yard stick determine barrel length. Use marked dowel to approximate
the Final Fit Position of the Front Sight Adapter Ring model you select. Ensure
that you check for any interference the Front Sight Adapter Ring may have with
your forearm stock. The Front Sight Adapter Ring is ½” thick.
The standard, unmodified Mosin Nagant 9130 barrel is tapered
along its length and is approximately 28.75″ long. The forward face of the
original front sight is at approximately 27.70″. Therefore the forward barrel
exposure is approximately 1.05″ (forward barrel exposure is length of barrel
that extends beyond the front sight).
Due to original barrel manufacturing techniques, some degree
of inconsistency in barrel tapers may exist. Therefore, the Final Fit Positions
given for the Front Sight Adapter Ring are approximations only and may vary
depending on individual barrel taper.

Fitment Example:
To determine your forward barrel exposure, subtract the
Final Fit Position from your actual barrel length. If your answer is a negative number
that model will NOT work.
Example, if your actual barrel length is 21.50” and you
select: Model MN-FSAR-D, then 21.50” – 19.50” = 2.00” , so the
forward barrel exposure after installation would be approximately
2”. or Model MN-FSAR-C, then 21.50” – 21.50” = 0.00” , so
the forward barrel exposure after installation would be approximately 0” or
flush with the end of barrel. or Model MN-FSAR-B, then 21.50” –
23.50” = -2.00” , so the forward barrel exposure after installation
would be approximately -2”. ***This model would NOT work!***
Installation
CAUTION! Improper installation or use may result in
damage property, severe injury, or loss of life. If for any reason this product
does not function properly, discontinue use immediately. Always practice proper
handling techniques, safety precautions, and ensure an UNLOADED condition.
We have made every reasonable effort to ensure the Front
Sight Adapter Ring will work with most original dovetailed Post & Globe
front sights from Model 9130’s ONLY. However, due to original manufacturing
variations and manipulation in the field, the adapter may need some consumer
modification in order to hold the original front sight. The adapter has been
designed to provide some degree of interference or “bite” when the original
front sight is pressed in. It should require some effort and should not just “fall
in”. If the Adapter opening that accepts the original front sight dovetail is
too large it will have to be closed somewhat. This can be easily done with a
bench vise or hammer and punch. If the adapter opening that accepts the
original front sight dovetail is too small it will have to be opened somewhat.
This can be easily done with a wedge. Complete instructions are supplied.
