Kel-Tec SUB2000 Magazine Sleeve Features The Kel-Tec SUB2000 Magazine Sleeve is purpose-built to adapt a Glock 17 Gen3 magazine for use in the SUB2000 carbine s magazine well ensuring the magazine locks up securely and feeds reliably. This factory-designed fit eliminates the wobble or feeding issues that can occur when using a magazine not specifically shaped for the host firearm. Because the SUB2000 is designed to accept common pistol magazines this sleeve gives owners a straightforward way to keep using magazines they may already own from a Glock 17 Gen3. Installation is simple sliding directly onto the magazine body without tools or modification. Molded from black polymer the sleeve is lightweight and durable enough to withstand repeated insertion and removal cycles at the range. Its compact design does not add meaningful bulk to the magazine keeping the SUB2000 s compact folded profile intact for storage or transport. For shooters who run both a Glock 17 Gen3 and a SUB2000 this sleeve simplifies magazine logistics by letting the same magazines serve both firearms. Kel-Tec s factory engineering ensures a dependable fit backed by the SUB2000 s reputation for practical magazine-compatible design.
