Review: Works as intended. - Nice quality clamp, I have it for a camera for airsoft gameplay. I did not realize it came with inserts for the 25.4mm diameter, but that's what the title means, for anyone wondering about the fitment. I tried 3d printing a mount similar, but in the end, metal or aluminum will always be a better option. and for the price it's worth it. Good quality, easy to install, thick steel for sturdiness.
Review: Red dot to scope f - This ring allows you to place your red dot right on top of your scope so you dont have to rotate the gun to aim. Easy to mount and align.
