If you shoot your Mosin Nagant with irons sights then you'll want to upgrade to a Smith-Sights adjustable front site. Built by hand using original Mosin Nagant front sight assemblies Smith-Sights gives you the best of both worlds, a modern adjustable front sight post and the classic lines of an original Mosin Nagant hooded sight.
The adjustable fiber optic front sight post comes in red for quickly acquiring a great sight picture and great better visiblity in low light hunting conditions. You'll see more of the target as your new front sight only covers 6-8" at 100 yards vs. 12+ inches blocked by the the original non adjustable sight.
Comes with both a standard black and red front sight post, hooded front sight cover, shim (in case you need it) and easy to follow installation instruction. Requires a 0.050 hex key not included.
