Gun Review: Keystone Adds Rounds With 722

Seven-shot Rifle Comes In Sporter, Classic, Varmint Models

Review And Photographs By Oleg Volk

Keystone Arms has long been known for single-shot .22-caliber bolt-actions for kids. Last year, they introduced a very unique repeater bolt action, which was released during the rimfire-ammunition shortage that happened not long ago. This gun came out with no fanfare and made very little impression in the gun industry. The Model 722, named for its seven-shot capacity and caliber, comes in three variants: the simple $262 Sporter, the more refined $315 Classic and the $340 heavy-barreled Varmint. They share all parts except the barrel and stock.

The bolt has a locking lug opposite the handle, which acts as a second lug, and the short length of the action permits a 20-inch barrel.

THE SEVEN-SHOT MAGAZINE is genius. The thick stainless-steel lips are smooth to the touch, and all seven rounds can be loaded quickly and effortlessly. Since all of the external edges are smoothly radiused, a handful of these mags can be carried in a pocket with no worry of them scratching each other.

You won’t find a magazine catch on this gun. The magazine is retained on both sides by a springy mag well. The magazine locks in solidly until the shooter pulls down on the magazine with moderate effort, and they cost around $22 each. Even though I have several, I found myself just reloading the same one in the field because the process was so quick and effortless.

The action is smooth and easy to run, and the symmetrical design operates with only a 50-degree throw, easily clearing even the largest scopes.

The seven-shot capacity is dictated by the curve of the ammunition stack. If there were more than seven, the cartridge would have to curve forward even more, requiring a more complex magazine body shape.

ALL VARIANTS OF the Model 722 come with a crisp 2-pound trigger with an overtravel adjustment. The bolt has a locking lug opposite the handle, which acts as a second lug. The action is smooth and easy to run. The symmetrical design operates with only a 50-degree throw, easily clearing even the largest scopes. The short 1.5-inch cycle distance makes for very quick loading. The short length of the action permits a 20-inch barrel on a very light and compact gun. The 13.25-inch length of pull makes it feel even smaller. The safety is a lever – forward for fire, back for safe. It clicks very positively, but the angle of throw is fairly small, so it’s sometimes hard to tell at a glance if it’s on. On the left side of the receiver there is a spring-loaded bolt retainer. The bolt does have to be cycled briskly for reliable ejection.

There isn’t a magazine release on this rifle. The magazine is retained by a springy magwell.

KEYSTONE ARMS’ SISTER company is Revolution Stocks, a premier aftermarket manufacturer. It’s no surprise that the stock quality for all three variants is superb, with a tight wood-to-metal finish. The decades of metalworking experience behind the Crickett brand also make for excellent action fit. Keystone didn’t skimp on the manufacturing process – even the trigger guard is a nicely machined part.

Just push the magazine in until it locks solidly into place, and pull down with moderate effort to remove.

THE CLASSIC IS lightweight at just 4.6 pounds, and feels even lighter, thanks to the good balance. The Varmint is a couple of pounds more, but the sculpted thumbhole stock makes

steadying it off-hand quite easy. The Classic comes standard with Williams Firesights, fiber optic front post and semibuckhorn rear that adjusts for windage and elevation. Picking up the front is very easy in any kind of light, but the bright fiber optic pipe on the front sight obscured at least 2.75 inches of the bull’s-eye, making precise alignment difficult. At best, my groups were 2 inches at 25 yards. After trying several kinds of ammunition, I gave up and scoped it with the dedicated Primary Arms 6x rimfire BDC scope in low rings and tried again. The results improved greatly: From prone at 80 yards, the CCI Green Tag ammo grouped at 1.25 inches, or about 1.5 minute of angle. Ammunition quality matters. Bulk .22 gave me 3MOA at best. Even with bulk Federal ammo, the BDC reticle made hits on pop cans placed 50 yards downrange routine. Shooting off of a lead sled indoors, without wind, produced 1.25MOA with Aguila Match, 1MOA with Aguila Super Extra subsonic and 2MOA with Federal 550-round bulk pack. I am guessing Green Tag would have come in at about 1.25MOA as well.

THE REAL ACCURACY testing was with the Varmint version. Prone at 25 yards produced a single seven-shot hole scarcely larger than the bullet diameter. Topped with the superb 6-24x Weaver with an adjustable objective, this rifle made extreme accuracy the default result. The slim 1-inch tube with a 40mm objective permitted low rings and thus minimal sight height over bore. The mildot reticle provided for drop compensation, and the focusable objective made for a crystal-clear view of the bull’s-eye obliterated by precision fire. Both CCI Green Tag and Aguila Rifle Match grouped near 0.6MOA, and Eley Match was right at 0.5MOA at 50 yards – a great performance for any rifle, and even more so for the budget-priced 722.

The Classic comes standard with Williams FireSights, fiber optic front post and semibuckhorn rear that adjusts for windage and elevation.

One exception to the versatility of the Varmint model comes from its match chamber incompatibility with the CCI Stinger hypervelocity round often used by actual varmint shooters. The Aguila equivalent works fine, as does the Winchester, but neither hypervelocity load equals the standard velocity loads in outright accuracy under controlled range conditions. In the real world with wind drift and imperfect range estimation, the faster loads perform almost as well as the match bullets.

Twin forend studs allow for simultaneous installation of a bipod and a shooting sling. Despite the greater weight, I consider the Varmint version the best of the three models not only for rested shooting but also for field hunting. The exception would be left-handed shooters, who would have to stick with the ambidextrous Classic stock design.

All variants of the Model 722 come with a crisp 2-pound trigger with an overtravel adjustment.

OTHER THAN THE QUICK but imprecise iron sights, Classic is a strong competitor to CZ455 Military Trainer. With optics, the 722 Varmint gives up nothing at all to the competition. Overall, the rifle is just fun to use. Its operation is so transparent that it feels like a natural extension of the marksman. ASJ
