I've settled on 7.62 x 51 as a the optimum carbine caliber fitting my needs. Now I just need to figure out what platform to launch it from...
I need advice on a suitable carbine chambered in 308/7.62 NATO and that is utterly reliable. Magazine capacity should be no less than 20 rds and barrel length should be between 16 and 20 inches. Again, reliability is the most important factor for me. Feel free to share your experiences, positive and negative, with carbines in 7.62 NATO. Thank you.
