TangoDown’s MK3 represents the next evolution of the company’s rifle magazine product line, offered as a significant step forward in TD’s modular magazine concept. Since a firearm is no better than its magazine, the company concentrated on making the MK3 the optimum element for your rifle.
UN12’s resident gear expert Chip Lasky takes a deep dive into the TangoDown MK3 in the upcoming issue of UN12, #22, on sale September 30. Here’s the abbreviated version.
The magazine body is a modular assembly, unitized and permanently bonded together for superior strength with no removeable floorplate. All feed lip and follower surfaces have been redesigned for smooth, positive feeding of 5.56 ammunition, including M855A1.

TangoDown’s advanced construction design allows for dissimilar resins to be joined together, placing the tensile strength or high impact resistance in the magazine body where needed. The MK3 magazine upper component offers extreme stiffness for feed lip rigidity and durability. The exposed MK3 magazine lower component features superior impact resistance with no floorplate.
An aggressive texture and prominent ribbing cover all manipulation surfaces for positive, no-slip handling in any environment. Ammunition status windows are provided on both sides. A choice of magazine shapes is offered, conventional flat bottom or TangoDown’s new unique monopod-use round bottom.
Easy, constant feeding is guaranteed by a bright white, anti-tilt, low-friction follower. A corrosion-resistant, heat-treated stainless-steel spring rounds out the assembly. Once assembled, components are permanently bonded together with advanced adhesives for a decades-long life span.
The MK3 is designed to slide easily into any single or double M4-style magazine pouch. Extraction is fast and secure with the heavily textured magazine body “steps,” manipulation is positive with the fore and aft molded-in ridges.
Magazine seating on a closed rifle bolt with the full 30-round capacity is easy, with no tapping required. Magazine loading is effortless, even by hand. Ammo status windows allow easy ammo checks, at a brief glance. The round-bottom variant is advantageous for competition or range drills/field use.

Finally, cleaning is fast and easy. The magazine body is unitized, with no disassembly required or even possible. A quick blast with compressed air through the upside-down ported follower clears any small dust or dirt debris inside the body.
Carbon coating due to extended suppressor use is easily cleaned with quick dunk in hot soapy water and used of a magazine brush (sold separately), then rinsed and left upside-down to dry.
The MK3 is intended for 5.56 x 45mm NATO cartridge use and will work in any AR15 or M16/M4 Mil-spec-pattern magazine well.
UN12 Issue 022, featuring Chip Lasky’s comprehensive overview of the TangoDown MK3 magazine, is available on newsstands and in the digital format September 30. Grab yours while it’s available!
