The lever-action rifle is almost uniquely American. It has been around for more than 150 years. Thousands of books, movies and television programs have been made featuring lever-action repeating rifles and carbines, and, as such, it has become a mainstay in the American psyche. Today, there is virtually a cult of lever-action rifle aficionados, and their presence in online chat rooms and forums remains robust. Concurrently, there is no denying the popularity of so-called “tactical” firearms. It almost seems that many believe it is not possible to survive a gunfight without at least a couple of Picatinny rails on their firearms. Several lever-action rifle manufacturers have bought into this and make versions of their long-standing lever guns with rails, composite stocks, threaded barrels and such.

A recent example of this comes from Big Horn Armory’s Black Thunder, a tactical version of its superb Model 89 lever-action rifle chambered in .500 Smith & Wesson Magnum. The Model 89 was launched in 2012 featuring an action based upon the Browning-designed Models 1886 and 1892. It is, in fact, sized right between these two rifles, hence the Model 89 name.

This latest iteration features a 16" threaded barrel made from with a beast of a muzzle brake designed by Big Horn Armor’s owner, Greg Buchel. It has four Picatinny rails attached, one Picatinny-style scout scope mount on top and three more 2.5" circumferentially around the M-Lok tip on the fore-end. The beefy receiver is finished in Hunter black or matte, as are all metal parts on the rifle. Sights are a Skinner Sights ghost-ring aperture for the rear and a Marble white-bead front sight. That receiver, as well as all the metal parts in it, are made from 17-4 PH stainless steel surface hardened to Rc82 by a nitriding process and continue to be manufactured by the stock removal method on CNC machinery. As such, the fit and finish remain near perfect. The fore-end and buttstock are U.S.-made black laminate to which a Pachmayr Decelerator recoil pad is attached, and it is finished with a synthetic satin clear coat. Magazine capacity is six rounds because of the shorter barrel and magazine.

I’ll confess that I wasn’t looking forward to shooting this rifle with this muzzle brake, because I have had some unpleasant experiences with brakes. My trepidation was unfounded. I took extra precautions by doubling up on the ear pro—my custom plugs and ear muffs. I used the same tactics when I took a Smith & Wesson .500 Magnum to Africa. If you think I am being a pansy, you haven’t had to deal with the hassle of hearing aids. Anyway, BHA’s muzzle brake was very effective in taming the .500 S&W Mag. recoil, even with the 500-grain Hard Cast Buffalo Bore loads. Simply holding the butt firmly and squarely to my shoulder, the fore-end never got close to jumping from my Sinclair rifle rest.

The precision invested in building these rifles, from the CNC-machining of the parts to the care-in-hand assembly lavished on these rifles at the company’s facility in Cody, Wyo., produces a rifle of rather remarkable accuracy, given the reputation of lever-action accuracy. To be sure, these are not benchrest competition rifles, nor was that the intention. Average group sizes were just a smidgen more than 3" at 100 yards, making this rifle a pretty reliable 200-yard medium- to large-game or self-defense gun. I suspect that better accuracy could be acquired by a shooter with younger eyes or attaching an optic to the top Picatinny rail.

One of the reasons that lever-action rifles and carbines remain popular after a century and a half in production is their inherent handiness and efficiency of delivering successive shots. The Dark Thunder is just 36" long and at 7 lbs., 12 ozs., making it an ideal truck gun, especially considering its overwhelming power. This rifle and its .500 S&W Mag. chambering is capable of handling bullets as light as 200 grains on up to 700 grains for those occasions where one might want to shoot through the length of a T. rex or stop a truck.

The Dark Thunder is, no doubt, an impressive piece of shooting machinery. Pulling it out of a scabbard will certainly garner the attention of those around you, especially with that 0.50" hole in the muzzle. This quality of workmanship and power comes at a price. You won’t find it in the bargain bin of a big-box sporting goods store either. The MSRP of $4,699 will likely put it beyond the reach of many, but for those who will not settle for anything but the very best, it is worth it.
