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.
