Barrel, Trigger, Furniture

Riding inside the handguard is a light profile, 16-inch chrome-moly barrel given a tough Melonite finish inside and out. It has a 1:8 twist, which proved optimal on the range, generating sub-MOA 3-shot groups with a smorgasbord of bullets weighing 55 to 77 grains.

The barrel is fitted with a mid-length, multi/mode adjustable gas block. Springfield supplies 3 different gas metering screws and a T-handle wrench along with each rifle, enabling the owner to fine-tune the gas system to specific ammunition—a process clearly explained in the owner’s manual. Finishing off the muzzle is Springfield’s artillery-looking, SA-Lite muzzle-brake. Those big baffles may look out of place on a .223, but are they ever effective! You can spot your shots through the scope with this brake.

The bolt carrier group is finished with super-hard Melonite as well, and carries a premium grade bolt. Operating the bolt carrier is Springfield’s generous-sized charging handle.

The pièce de résistance in the fire-control system is a Melonite-finished trigger averaging 4 pounds, 3 ounces, for 10 pulls on a Lyman electronic scale. It’s a short-reset, single-stage, match-quality trigger made in heaven. I would say it’s the finest out-of-the-box trigger on a modestly priced AR available today.

The Edge sports some upgraded furniture, featuring Bravo Company’s rock-solid 6-position buttstock and their Mod 3 pistol grip with its internal storage compartment.
