*The BBS™ is designed to fit over standard buffer weights and is compatible with most buffers available on the market. The system includes a drop-over spacer that rests on the buffer, preventing the spring from overextending the tapered buffer body.

Warning: Avoid attempting to "snap" the spring onto the ledge of the buffer weight like standard springs. Instead, simply slide it onto the buffer where it should rest atop the ledge. If using the included spacer, ensure it is placed first before installing the spring.

*The BBS™ is intended for use with standard carbine-length buffer tubes only. It is NOT compatible with rifle-length or A5 buffer tubes.
