abstract:The Picatinny rail ( or ), also known as a MIL-STD-1913 rail, STANAG 2324 rail, or tactical rail, is a bracket used on some firearms in order to provide a standardized mounting platform for accessories and attachments, similar to the Weaver rail mount.
This is particularly true for the picatinnyrail mount for rifles, though we're thinking you'll have some other audio artifacts to deal with in that case.
