Solid platform, required modifications - Vltor CASV-14: M14 Rail System

Installed on my M1A scout squad with the factory synthetic stock, and for the most part very easy to install. However, the rear mounting block required modification as the angles on the rear mounting block were different than those on the stripper clip guide. This resulted in the top of the rear mounting block being too thick to slide into the stripper clip guide. Material was carefully removed from the rear mounting block with a file, then was tapped into place with a brass punch. Although I was able to make mine fit with no noticeable shifts on a leveled optic, having to physically modify it was very off-putting and as such I can only recommend this rail system for someone who is willing to make such modifications.
