was browsing thew the selection of junk at Academy for a cheap rail or some way to have a vertical grip (i personally shoot better with them) and was looking at the RVG,, now i loved my MOE handguards with the MVG,, it was the most comfortable vertical grip i ever used (i hate all there pistol grips though) but i like the standard hand guards and didnt want to buy both
so i opened the package there in the store to take a look and seen theses other small parts that came with the RVG
well after seeing this i thought hmm, it may be just the right spacing to fit the existing holes in the handguards i have now, it was tight but it pushed in with my thumbs.
now i did have to drill two small holes in the black inner heat shield for the screws to pass thru, i could have cut the screw shorter too as they were way to long.
but i love the end result, a nice clean look with the function i was looking for with no extra unnecessary rail space
