Checking out the KelTec SUB2000 in 5.7
KelTec recently added a 5.7x28mm chambering to its popular third-generation SUB2000 carbine line, and we have the full review.
Introduced in 2001 with a host of different common magazine well choices, the SUB2000’s biggest claim to fame is that it folds neatly in half for storage.
Evolving into a second and currently third generation since then, the pistol-caliber carbine had previously been offered in 9mm or .40 S&W, with KelTec adding 5.7 to the catalog late last year, followed by 10mm Auto more recently.
The 5.7 SUB2000 uses common 20 and 30-round FN Five-seveN pattern magazines. It can also accept aftermarket mags such as ProMag’s 55-round drum. Running from a blowback action, standard features include lots of integrated M-LOK and Picatinny rails for accessories and optics. It is also threaded (1/2×28 TPI) for easy suppressor use.
The KelTec SUB2000 Gen 3 Carbine in 5.7 is 30.45 inches when fully extended and ready to go. We added the 2 MOA Aimpoint Patrol Rifle Optic on a QRP2 mount. Weight, so equipped, is just 4.86 pounds.
Folded, the SUB2000 Gen 3 runs just 16.15 inches in overall length and can be deployed in seconds.
We had issues with FTEs early in testing on the factory-supplied magazine. This problem abated the more we shot the gun, and with the use of FN-made mags. The second half of the test proved it to be more reliable. Lightweight, in most configurations, the gun remained under 6 pounds even when loaded and sporting a light, suppressor, and optic. It is simple and intuitive to use, functional and deploys rapidly.
