    Ample RDS Tool

    Fits the RMR adjustment dails perfectly. Works much better than a brass casing and it allows for fine adjustments.

    Well made tool for adjusting my Trijicon RMR without scratching or damaging the small adjustment screws. Ordering was easy and it was shipped expeditiously.

    Good things come In small packages

    After trying to buy an Ampule RDS tool from a local store, ended up needing to order it direct from rail scales. When it arrived, I was surprised it was shorter than I was expecting. But the feel and build was amazing. Tactile in the hand and definitely more convenient than to carry around multiple tools to adjust my sights

    A must have for you range kit, keeps you from Scarring up your expensive optics because it fits in the grove. This is a very well made tool.

    Great tool

    It’s one of those things like the GI p-38 can opener. Overlooked until you need it, but a priceless necessity when you do. I’m going to order more for myself and some to give to friends with red dots.

    Rail Scales RMR sight adjustment tool

    Posted by Ryan on Apr 30th 2022

    High quality, blazing fast shipping. The RMR adjustment knobs can be a burden, most coins don’t exactly fit in there. A $550+ optic investment with coin slot shaped adjustment points scratch easily with a flat head screwdriver, this tool fits in there like a glove scratch free. This tool fills the void, 5 stars highly recommend, must have if you own high end optics.
