Several companies offer a single shot 30-30. The NEF guns are the cheapest . . by far. Strong lock up,aftermarket stuff available for them also. I will eventually put on a youth sized stock or have the existing stock cut down to 12.5-13.0 inches.
At this time I have 7 different NEF Handi Rifles. Have had many more over the years. They all shoot well,are reasonably accurate,and have a good trigger pull with a little tinkering. My NEF Handi Rifle (AAC Edition) chambered in 300BLK ended up shooting better than most AR's . . . a lot better.
The NEF 30-30 has a 10 twist bbl. --- SAWMAN
