3 AR-Style Rifles Ready for 3-Gun

Although the spent case is being kicked out on the right side of the shooter, like most Stag rifle models, the 3G is also available in a left-handed version as well.

Stag Arms 3G

Stag Arms is well known for producing left handed AR-15 style rifles, as well as the conventional right handed models. They got noticed for the southpaw aspect, but built their name by producing high quality rifles. The 3G is their competition ready rifle and can be ordered in a right or left hand model. I have a couple of southpaw shooting buddies who are very happy about that.

Stag Arms worked with their 3-gun shooting team to develop the new rifle. There are in truth a few things I would change. For example, I would add an extended charging handle latch, a tactical bolt release and possibly an ambi-safety. But these are small things and the truth is, this gun is competition ready out of the box. The one major change is I would also use a different muzzle brake as the one in my rifle over-compensates and drives the muzzle too low. All in all, minor issues on a fine rifle.

The rifle uses an 18-inch stainless-steel semi-heavy barrel that measures .727-inch near the muzzle and uses a 1:8 twist rate. The chamber is 5.56 NATO, so it can fire both 5.56 and .223 Remington ammo. The barrel has six flutes that are interrupted by the gas block for the rifle-length gas system. The last ¾ inch of the barrel is stepped down to .705-inch to the muzzle.

The barrel is fitted with a 21⁄4-inch long compensator installed with a crush washer. The gun is fitted with a Samson Evolution free-floating handguard. This handguard comes with a rail along the top. There are holes along the sides and bottom to add more rails if you want them. The sides are skeletonized with a double row of cuts on each side to shave off weight and aid heat dissipation. The diameter of the handguard is 1.825-inches, which is easy to grip. The 15-inch handguard extends well past the low profile gas block.

Stag Arms 3G AR-15.Most top 3-gun shooters never hold the gun in front of the magazine well.  Instead, they will have the weak hand extended way out on the front of the gun for action shooting. This gives much better control of the rifle for lateral movement during rapid target transition. Try this with a short handguard and all you get is burned fingers. I guess my point is this long handguard proves to me that Stag listened to some real shooters when designing the rifle.

When it comes to triggers, many AR builders are stuck on “Mil Spec Stupid” and forget that shooters need good triggers. It’s not uncommon to have precision targets at 500 or 600 yards or even farther in a 3-gun match. It’s a huge handicap to have a 10 pound “battle trigger” that’s rougher than Rosie O’Donnell’s personality.

Unless you order a better trigger as an option, almost all rifles will need an expensive replacement before using them in competition.

One popular replacement trigger is the Geissele Super 3-Gun trigger. This STAG rifle comes with that trigger as standard equipment. It uses what Geissele calls a ‘hybrid pull.” It’s a longer pull than most match-grade, single-stage triggers, but smooth and clean. On my rifle it breaks at just slightly over 3 pounds.

The buttstock and pistol grip are from Magpul, featuring their collapsible ACS buttstock and their MOE hard plastic pistol grip. Both have storage compartments.

I accuracy tested the rifle by shooting three different factory loads and one handload using bullets ranging from 50-grains to 75-grains. The average for three, 5-shot groups with each of the four loads was 1.23-inches, which is excellent accuracy in any rifle you plan to shoot, particularly right out of the box.
