The basic stock "period" lever action rifle WAS the tactical battle rifle of its day, and if you really think about it, nothing has changed regarding the practicality and functionality of this platform to this day. Bolt action rifles didn't really improve on the overall firepower, rapidity of fire or accuracy over the lever action rifle. Not really. Magazine fed weapons did improve the speed of reloading and of course the ability of choosing between semi-auto and full-auto drastically improved number of rounds down range, but not necessarily accuracy of rounds on target.
For those of us living out on the Left Coast the option of owning a modern day battle rifle has pretty much been eliminated due to socialist snowflake laws and legal hassles. So in looking for an alternative I've been leaning heavily towards Lever Actions to defend home and hearth. If anyone has actually been to a Cowboy Action event, you can't help but be impressed with just how fast some of those folks can light off and really work an "Ol Lever" gun. Impressive to say the least, not to mention hitting all those gongs like clockwork. Of course they do PRACTICE A LOT, far more than even the modern day soldier today. Sad to say.
The ability to install modern optics and synthetic stocks is a plus. Also the means to improve the ability to quickly acquire targets, improve accuracy with modern optics and if you must add other "Tactic-Kool" toys like lights and even lasers they are readily available for those so inclined.
One advantage of the lever rifle is the ability to top off the magazines on the fly....not to mention not having to carry extra magazines like modern battle rifles. I consider both the lever and bolt guns to be weapons of true riflemen....i.e. One shot - One kill, rather than the spray and pray often seen in actual combat and depicted in the cinema.
As my old training Gunny used to say: "It's not rounds down range that count - It's rounds on target!"
