USA – -( Looking for a little more versatility and more boom than pew, it was time to look for an AR-10.  When I bought my first real bolt gun I chose one in .308.

The .308 cartridge is more than sixty years old.  All the long-range craze is focused on 6.5 Creedmoor (last year, this year it seems 6mm Creedmoor is the new hotness), but .308 is widely available in a long list of loads and still a solid performer.  There’s a certain level of comfort in being able to find the ammo you need just about anywhere.

Fans of Eugene Stoner may also appreciate that the AR-10 was his original intent before the military made the change to 5.56x45mm.  .308 hits harder farther out than .223 and is a more accepted hunting cartridge.  Combine that with the availability of ammunition ranging from cheap military surplus to premium boutique loads and chances are you can find the bullet to match you need.  Besides, who doesn’t love the idea of having a good thumper on hand?

Stag Arms Model 10S Rifle

One of the challenges with the AR-10 platform stems from the fact that it was never adopted by the military.  There is no “mil-spec”.  As a veteran I strongly advocate that “mil-spec” is not synonymous with “best”.  It does however serve as a convenient assurance of parts interchangeability.  The lack of a mil-spec AR-10 can be a deterrent when shopping.  The greatest custom rifle in the world quickly loses appeal when you’re locked into using obscure parts for repair or personalization.  Stag kept this in mind with the Stag Arms Model 10S Rifle which uses standard furniture and most importantly standard trigger parts.  This came into play for us when we wanted to replace the standard trigger with one from Geissele.  At Erika’s request we also tamed the recoil a bit with a stock from Adaptive Tactical.

On to this particular Stag Arms Model 10S Rifle.  Get a look for yourself with the tabletop video here:

Perhaps the victim of range talk during my “prepubescent” years as a shooter, I had always thought that a .308 needed a long heavy barrel if one expected great accuracy.  That may have been true then, but certainly isn’t now with the Stag 10S’s 16″ barrel.  Though built more like a traditional battle rifle, the 10S proved itself to be more accurate than we were.  The grouping seen at right was obtained with five-shot groups from two different shooters for a total of ten shots per bullet type.  The barrel was hot and no break given for cooling.  The gun obviously didn’t like the lighter 150gr loads, but performed well with 168gr loads from Hornady, Federal, and Sig.

After spending both some range time and field time with the Model 10S I think Stag has built a rifle that Eugene Stoner would be proud of.  It performed equally as well on the bench as it did in quick action.  This is a rifle that could be used for hunting, as a bigger alternative to an AR-15, or at the bench perfecting your rifle marksmanship.  See the rifle in action for yourself (including a failure) in the Shooting Impressions video below.

Something I continue to find myself curious about re these AR-15 type rifles, that these days are available in several different calibers/cartridge chamberings. Seems like none of the above mentioned rifles come with a proper rear sight, that is one adjustable for both elevation and windage. Optical sights are fine, if they turn out to be what one wants to use, however proper iron sighs offer great utility, plus the virtue of low, virtually non existent bulk and weight. Attention rifle and accessory makers, how come no proper iron sights, or rear sight if you prefer?


I’m not a great fan of .308. To me it’s .30-06 lite. But I admit it’s a much better cartridge than .223 Remington. A comment about ammo availability. Some 55 years ago when I began deer hunting in the mountains of VA, I considered what for my hunting scene would be the best caliber choice. I stopped at a local gas station and looked at the ammo they had on the shelves in case I forgot mine at home. For deer, the choices (rifle ammo) were .30-30, .270, and .30-06. Since I was hunting primarily in wooded areas, I decided… Read more »
