In the early 1970s this scaling-down concept was further developed. The resulting modified link had a slightly different angle of pitch and was adapted as the M27 link for use with the FN Minimi/ M249 SAW.

Design details
Each M27 link consists of a single piece of metal curved into two partial cylinders, into which adjacent rounds slide. Like the M13 link, the M27 link is a push-through design. Rounds are extracted by pushing forward out of the link. With the round freed, the link disintegrates (detaches from the belt) and is ejected. This is in contrast with older belt systems which were typically made of fabric and were fed straight through the weapon without disintegrating. MIL-L-63532C stipulates that the force to strip a NATO approved round from the M27 link should be between and the belt should have a minimal tensile strength of . A single M27 link weighs approximately ./ref> The links often have an extra anti-corrosion surface treatment, generally (oil impregnated) black phosphate, and can be collected and reassembled by hand with fresh ammunition, but in practice this is not commonly done as it is labor-intensive, and the inexpensive links are considered disposable.
