Downeast
1609 Open-Back Polymer Ruck Frame (Tan 499) - New
The MOLLE
Medium Rucksack Frame (officially manufactured by Downeast Frame as the Model
1609) is a cutting-edge, high-strength structural component engineered
exclusively for the U.S. Army's Medium Rucksack system in MultiCam / OCP
(Operational Camouflage Pattern). Designed to replace bulky legacy frames, this
compact perimeter frame features an innovative open-back architecture
specifically tailored to bridge comfortably over standard-issue body armor,
plate carriers, and rear ballistic sheets without creating painful hot spots or
disrupting the load center of gravity.
Molded from a
proprietary, impact-resistant polymer matrix, the 1609 frame is built to
withstand extreme battlefield abuse. It remains completely shatterproof down to
sub-zero arctic temperatures and will not twist, bend, or warp when loaded down
with heavy ammunition blocks or tactical equipment.
In New
(Unissued) condition, this frame is factory-fresh, clean, and completely
rigid. It is finished in official Tan 499, making it an essential,
drop-in replacement part to repair a broken ruck pack, build out a custom field
pack, or complete an authentic OCP Medium Assault Rucksack loadout.
