For those who need a reliable 16-inch barreled rifle that handles both supersonic and subsonic 300 Blackout ammunition, this model provides a solid foundation for home defense, target shooting, and medium-range hunting applications. As a licensed FFL retailer, we stock this firearm part for customers who understand the value of a proven manufacturer and a cartridge that bridges the gap between close-quarters performance and suppressed operation.

What This Product Is and Who It Is For

The Barrett REC7 Gen II Direct Impingement in 300 Blackout is a semi-automatic rifle chambered in .300 AAC Blackout, featuring a 16-inch barrel and a 30-round magazine capacity. This specific variant moves away from Barrett’s traditional gas-piston system to a direct impingement design, which reduces reciprocating mass and can improve felt recoil management for certain shooters. This product is intended for target shooters who want a flat-shooting rifle at the range, homeowners seeking a capable defensive carbine, and hunters pursuing deer or hogs at moderate distances with appropriate ammunition. Collectors will also note the Barrett name and the Gen II refinements, which include an improved handguard and bolt carrier group design.

Feature Deep-Dive

The Barrett REC7 Gen II DI in 300 Blackout incorporates several refinements that distinguish it from earlier REC7 generations. The direct impingement system reduces the weight of the bolt carrier group and eliminates the need for a gas piston assembly, which can simplify maintenance for shooters who prefer a more traditional AR-15 pattern. This design choice also lowers the reciprocating mass, which can contribute to a flatter recoil impulse when firing supersonic ammunition, making follow-up shots more consistent during range sessions or defensive drills.

The 16-inch barrel is cold hammer-forged from 4140 steel and features a 1:8 twist rate, which is well-suited for stabilizing both 110-grain supersonic loads and 220-grain subsonic projectiles. The barrel is finished with a corrosion-resistant salt bath nitride treatment, which extends service life and simplifies cleaning. The mid-length gas system provides a balanced dwell time, reducing port pressure compared to carbine-length systems, which can improve reliability with suppressed fire and reduce felt recoil.

The free-floated M-LOK handguard is machined from 6061-T6 aluminum and provides continuous top rail for mounting optics, with M-LOK slots at the 3, 6, and 9 o’clock positions for lights, lasers, or foregrips. The handguard is secured to the barrel nut with a clamping system that maintains zero for accessories and prevents shift under recoil. The barrel nut itself is torqued to spec and staked, ensuring consistent barrel alignment over thousands of rounds.

The upper receiver is machined from a billet 7075-T6 aluminum extrusion and features an integral Picatinny rail that is true to MIL-STD-1913 specifications. The ejection port has been enlarged for reliable ejection of 300 Blackout cartridges, and the forward assist is serrated for positive engagement. The bolt carrier group is chrome-lined inside the carrier and features a Carpenter 158 steel bolt with shot-peened and magnetic particle inspected surfaces for structural integrity.

The lower receiver uses a standard AR-15 trigger group (single-stage, approximately 5.5 to 6.5 pounds pull weight) with a crisp break and minimal overtravel. The lower also includes a flared magazine well for faster reloads and an ambidextrous bolt catch/release for left-handed shooters. The buffer tube is mil-spec diameter and uses a standard carbine buffer and spring, which allows for easy customization with aftermarket stocks and buffers.

Barrett includes a 30-round magazine with the rifle, typically a Magpul PMAG or Lancer L5AWM, both of which are reliable in 300 Blackout applications. The rifle is also compatible with standard AR-15 lower parts, grips, and stocks, giving owners a wide range of aftermarket options for personalization. The overall fit and finish are consistent with Barrett’s manufacturing standards, with tight receiver tolerances and a uniform anodized coating that resists wear from handling and environmental exposure.

Ideal Use Cases

• Home Defense: The 300 Blackout cartridge, especially with subsonic loads, offers reduced overpenetration risk compared to 5.56 NATO, and the 16-inch barrel provides sufficient velocity for defensive ammunition without excessive muzzle blast indoors. The direct impingement system keeps weight low for maneuverability in tight spaces.
• Target Shooting: The 1:8 twist barrel and free-floated handguard support consistent accuracy with a variety of factory loads, making this rifle suitable for steel plate shooting, paper target work at 100 to 300 yards, and informal competitions. The mid-length gas system and adjustable stock allow shooters to find a comfortable and repeatable position.
• Hunting: For medium game such as white-tailed deer or feral hogs at ranges up to 200 yards, supersonic 300 Blackout ammunition (e.g., 110-grain Barnes TAC-TX or 125-grain Nosler Ballistic Tip) delivers adequate energy and terminal performance. The rifle’s weight and balance are suitable for carrying in field conditions.
• Suppressed Shooting: The 5/8×24 muzzle threads and mid-length gas system are optimized for suppressor use, reducing gas blowback and port noise when using a quality 30-caliber suppressor. Subsonic ammunition cycles reliably in this platform when properly tuned or with standard ammunition.

Compatibility Notes

• Ammunition: This rifle is designed for .300 AAC Blackout ammunition only. Do not use .300 Whisper or 7.62x39mm ammunition. It functions with both supersonic (110-125 grain) and subsonic (200-220 grain) loads, though subsonic ammunition may require a suppressor or heavier buffer for reliable cycling with certain loads.
• Holsters: Not applicable for a full-size rifle. For storage, consider a soft case, hard case, or gun safe with rifle rack.
• Magazines: Uses standard AR-15/M16 pattern magazines. Most 5.56mm magazines will function with 300 Blackout, but dedicated 300 Blackout magazines (often with a different follower or internal geometry) can improve reliability with subsonic rounds. The included 30-round magazine is compatible with most AR-15 lower receivers.
• Accessories: The M-LOK handguard accepts all M-LOK compatible accessories (lights, grips, bipods). The Picatinny top rail accepts any standard scope mount, red dot, or iron sight set. Muzzle devices with 5/8×24 threads (including suppressors, flash hiders, and compensators) are compatible. The buffer tube accepts standard AR-15 carbine stocks.
• Parts Interchangeability: The upper and lower receivers are compatible with most mil-spec AR-15 parts, including triggers, grips, and buffer systems. The barrel extension is standard AR-15 pattern, allowing for future barrel swaps with qualified gunsmiths.
