Ranger Bands Mixed 35 Count Made from EPDM Rubber for Survival, Emergency Tinder and Strapping Gear of Various Sizes Made in The USA NGE61972

Any of yours sizes fit around an AR-15 keymod for a flashlight button

Will they fit around an AR butt stock to secure sling? Also, how well do they stand up to heat to secure light pressure switch on handguard?

Will these tear easily if punctured? I want to use as a replacement to the bands on an Accubat, and would have to poke a hole in them (and cut them).

When i first bought these i remember seeing an option to get only specific sizes. I only want small. Is this available?
