2how has a point, what is tactical??
Concerned with the middle level of planning and delivery. Tactical concerns are around how to achieve an objective (as developed in the strategy) and providing a framework for the operational delivery, or something developed for a particular objective. EG... Something that can be used in low light, night time, day time, be accurate, hard hitting, capable of multiple shots ( how many? depends on the field of play ), might need to be short, might need to be very accurate, or ok to 200 meters.
Well a lever action could certainly fulfill this role.

XS sights does have a long upper rail, so you can mount a rearward or forward optical sight, or a rifle scope mounted forward with a ANPVS 14 BEHIND for night vision capability. I have not called them yet, but they do have in the catalogue, a tri rail forend that should be coming out about now. Now you can mount lights, bipods, lasers and coffee grinders to your hearts content

There is one advantage to a lever gun, it can be reloaded and kept full on the run without dropping a magazine or opening the bolt. You don't have to carry spare magazines just ammo. A rifle caliber like 30-30, you could carry 200 rounds easy in a pouch on the strong side and keep feeding it all day. The full length winchesters I believe would hold 7 rounds in the tube, of course the pistol calibers can hold 10 rounds of 44 mag, 357 mag or 45 long colt, I found you could get 12, 44 specials, or 38 specials in the tube and with a 16" barrel have close to the same velocity as a magnum out of a 6" pistol.

and you could carry 400 rounds of the short stuff.
I have a Marlin 336 in 30-30 that I put a Trijicon Reflex sight on, with an ARMS quick release mount, and it is really fast, don't need batteries, works day or night. I will get a XS tri rail for it. As of now it is Tiger striped dura coat and I will have to redo that when the rail is attached. Once I have the rail, then a light system, ( probably a Safariland ) Laser, good single point sling system and bipod will complete the rifle. Sounds funny don't it.

Best tool for the job, maybe not, wrong tool for the job, NO.
