The Kel Tec plr 16 is a nice little "pistol" chambered in 5.56x45 (.223). Its design is similar to the AK, M-14, and M1 Garand, making it incredibly reliable. Simply due to the size, price, accessories, and potential capabilities the Kel Tec plr 16 is one great PDW (Personal Defense Weapon). However, it is sporting the 5.56x45 (.223), witch is one extremely criticized round, people love it or hate it, I hate it. Caliber conversion kits are cheap (depending where you get them) so upgrade it to a 6.8 spc (or any other round you would prefer). Thanks for reading, I hope this post helped.
