Great product - UTG Pro Tactical Mosin Nagant Tri-Rail Mount

GREAT PRODUCT. I installed the system in 10-15 mins (Use the Proper Drift Pin to remove the original pins, and you won't have a problem). The machined mount plate allows for a solid fit. The side pin holes on the rear site mount were not aligned, however when I compared it to the original rear sight mount, I found that the defect was on the Mosin side (the original pin alignment was not correct). I re-drilled the pin hole to the proper dimension & alignment, and everything fit perfectly. If I ever choose to remount the old sight, I will simply use a slightly larger drift pin. After 200+ round through this system, I have not had any zero drift problems. I would recommend that you start your zero at 25 yds, then 50, then 100 . . and finally at 200 yards. By walking in the zero you will also get a feel for the rifle.
Pros: Ease of Installation - ROCK SOLID
Cons: Side Rails
