About This Firearm
The Springfield Armory SAINT is a mid-length semi-automatic AR-15 in 5.56 NATO built for range work and home defense. Springfield Armory no longer makes it, so it is a used buy. It came with a full iron sight picture, an A2 front sight base pinned to the barrel that Springfield called unbreakable and foolproof, with a low-profile adjustable flip-up rear behind it.
One magazine came with it and no case, unlike the Victor and Edge versions of the same rifle, which both shipped in a padded one. Bravo Company supplies the M-LOK handguard and the GUNFIGHTER Mod 0 stock. The gas system is mid-length on a pinned block. The trigger is a nickel-boron-coated GI single-stage and the safety is single-sided, so a left-handed shooter buys a selector.
If you're cross-shopping, a Springfield Armory SAINT Victor is discontinued as well, weighs 0.13 lbs less and swaps the fixed front base for flip-up sights at both ends, a muzzle brake and a padded case. A Smith & Wesson M&P 15 Sport III has an MSRP of $799, is 0.17 lbs lighter, free-floats its barrel and comes with no sights. The SAINT's pinned front base puts iron sights on the rifle, and a low-mounted optic looks through it.

Strengths & Limitations
- The bolt carrier group is an M16 profile with a Carpenter 158 steel bolt, HPT and MPI tested and Melonite finished.
- The receivers are forged 7075-T6 with Springfield's Accu-Tite tension system, which takes the play out of the upper-to-lower fit.
- The barrel is chrome moly vanadium with a Melonite finish and a 1:8 twist, which covers bulk 55-grain ammunition and heavier match bullets.
- No thread pitch was ever marked at the muzzle behind the A2 flash hider, so a brake or a suppressor mount means measuring.
- The Bravo Company handguard is not free-floated, so a tight sling or a bipod loaded against it presses on the barrel.
- The trigger is a GI single-stage with a coating, where the Victor and Edge versions both moved to a flat one.

Frequently Asked Questions
How does it differ from the SAINT Victor?
The Victor free-floats its barrel under an aluminum M-LOK handguard held by Springfield's own locking tabs, fits flip-up sights at both ends instead of a fixed front base, and uses a flat GI trigger and a muzzle brake.
Will M-LOK accessories fit the handguard?
Yes. It is a Bravo Company M-LOK handguard, so lights, hand stops and sling mounts bolt straight to it.
What magazines does it take?
Any AR-15 magazine. One came with the rifle.
